(B) Apples 3 months after they had been wounded and inoculated with fungi Penicillium and Botrytis with (right) or without (left) treatment with the biocontrol bacterium Pseudomonas syringae (BioSave 110). When added to the fungus conidia during the 4 weeks prior to the picking-ripe stage the exudates significantly increased the aggressiveness of the pathogen on plum and nectarine fruits. PubMed Central  Raper KB, Thom C: Penicillium digitatum. 1. Fungal rots are one of the main causes of large economic losses and deterioration in the quality and nutrient composition of fruits during the postharvest stage. 2. Fungal resistance to these chemicals, along with consumer pressure for safer control methods is providing the impetus for alternative treatments based on generally regarded as safe compounds in combination with heat treatments and biological control agents, such as naturally occurring bacteria and yeasts. (A) Oranges treated with yeasts (right) remained healthy, whereas oranges not treated with yeast developed extensive decay following inoculation with Penicillium. The efficacy of thin-film diamond coated electrodes (DiaCell 101) for disinfection of water artificially contaminated with Penicillium digitatum and Pseudomonas spp. 1999, 89: 716-721. People are commonly exposed to the spores of this airborne pathogen every day. Proceedings of the Florida State Horticultural Society, 93:305-307. Penicillium digitatum possess a 199 bp insertion and 126 bp tandem repeat transcriptional enhancer element with resistance to prochloraz [ 10, 11 ]. Aw 0.78 - 0.88 (5) A wide number of organisms have placed in this genera. The fruiting structures (penicilli) of Penicillium from this patient have a brush-like appearance; the spores of Penicillium digitatum are typically elliptical under the microscope. # 93546-NE-001 . PubMed Central  Penicillium marneffei infection found in both immunocompetent and immunosuppressed patients. Antimicrob Agents Chemother. Prangolarin by itself enhanced P. digitatum development on wounded epicarps of lemons, resulting in the development of green mold symptoms because of the production of masses of conidiophores and conidia (Arimoto et al., 1995). The effectiveness of this fungistatic gas is pathogen dependent and is greatly enhanced in combination with a low-O 2 atmosphere (2.3%). 2001, 120: 177-10.1378/chest.120.1.177. Several studies indicated that grape berry exudates stimulated B. cinerea spore germination and that stimulation increased during the last month of fruit ripening. Part of By continuing you agree to the use of cookies. Following cycloheximide application, inoculation of apples with the citrus pathogen, P. digitatum resulted in green mold rot development, although the fungus does not normally attack apple fruits. Ascorbic acid and a number of terpene compounds in citrus fruits, much like their stimulating effect on the germination of P. digitatum spores, can also stimulate mycelial growth of this fungus, which is specific to citrus fruits (Pelser and Eckert, 1977; French et al., 1978). Naomi Tsurikisawa. Spores of Botrytis cinerea, the causal agent of gray mold, though capable of germination in pure water to some degree, cannot infect strawberries or cabbage leaves without external nutrients (Jarvis, 1962; Yoder and Whalen, 1975). Penicillium ascomycetous fungiare microscopic organisms that are of major importance in the natural environment, in the production of foods and in the pharmaceutical industry. Comparison of control (right) and PUVC (248 nm) excimer laser-treated (left) oranges inoculated with ∼2×104 cfu of Penicillium digitatum at ∼5 mm under the epidermis. However, in several cases, antagonistic yeasts can also act as inducers of resistance in the host tissue. (2000) found that the antagonistic yeast-like fungus, Aureobasidium pullulans multiplied rapidly in apple wounds, and reduced decay incidence in apples inoculated with Botrytis cinerea and P. expansum.

Penicillium rot of pineapple was reduced considerably by spraying the fruit with nonpathogenic strains of the pathogen. Holmes LG, Eckert JW: Sensitivity of Penicillium digitatum and P. italicum to postharvest citrus fungicides in California. Penicillium species are among the most common fungi in the environment and are usually considered non-pathogenic to humans [1]. All authors read and approved the final manuscript. Spread of Penicillium digitatum and Penicillium italicum during contact between citrus fruits. Mascotte, FL 34753 Additional index words. Penicillium species are among the most common fungi present in the environment and are usually considered non-pathogenic to humans. BMC Pulm Med 13, 16 (2013). Electrolysis process was performed with different operation conditions: current densities at 4, 8, and 12A and water flow rate at 150, 300, and 600 L/h. Partial sequences of the beta-tubulin gene were determined by using the primers Bt2a and Bt2b for PCR amplification and sequencing and underwent a BLAST search at the National Centre for Biotechnology Information, these results confirmed that the isolated fungus was P. digitatum. Silvia A. Valencia-Chamorro † ‡ Lluís Palou † Miguel A. del Río † María B. Pérez-Gago * † § Google Scholar. Particularly, the organism has been used to protect apples from postharvest fruit-rotting fungi (that is, Botrytis cinerea and Penicillium expansum) and to prevent postharvest diseases caused by several other fungi (P. expansum, Penicillium italicum, Penicillium digitatum, B. cinerea, Colletotrichum capsici, Rhizopus stolonifer, Rhizopus nigricans, and Botryodiplodia theobromae). Penicillium digitatum and Geotrichum candidum are Conidia germination and germ tube growth of Penicillium digitatim in 1% (v/v) orange juice dialysate at several pH values. Article  Hansfordia (Dicyma) pulvinata is a destructive parasite on many dematiaceous conidial fungi (Hepperly 1986), particularly Cercospora (Hawksworth 1981b), but also Passalora (Mycovellosiella, Cladosporium, Fulvia) fulva on tomato (Peresse and Le Picard 1980; Le Picard and Trique 1987), and P. (Cercosporidium, Phaeoisariopsis) personata on peanut leaves (Mitchell et al. 1981), which produces a diffusible toxin and induces vesicular deformations in its host. (1978) showed that the addition of CO (5 or 10%) to a low-O2 atmosphere (4%) reduced the incidence and severity of the gray mold decay in Botrytis cinerea-inoculated tomatoes at their mature-green or pink stage. and other filamentous fungi: report from SENTRY antimicrobial surveillance program, 2000. Once the citrus Penicillium became established in the apple, it progressed at a higher rate than that of the apple Penicillium. The addition of CO to the atmosphere results in the suppression of various fungi sensitive to the gas, such as Penicillium digitatum, P. italicum and Monilinia fructicola. Anamorphic Ascomycota also host necrotrophic parasites. The effectiveness of this fungistatic gas is pathogen dependent and is greatly enhanced in combination with a low-O2 atmosphere (2.3%). ], Ganoderma sp. Penicillium growth can still occur indoors even if the relative humidity is low, as long as there is sufficient moisture available on a given surface. Also, significant reduction of citrus green mold (caused by Penicillium digitatum) was obtained by treating the fruit with antagonistic yeasts (Fig. In that connection, a lot of components are used to create new food supplements, genetically engineered foods, and great food alternatives. Abstract The association of cereals with fungi cannot be disregarded as their manifestation in our foods poses serious health risks. The discomycete Bisporella pallescens (synonym Calycella monilifera) fruits densely on the conspicuous black conidial patches of Bispora antennata on tree stumps (Jahn 1968). However, the cavity became larger and thicker-walled (Figure 1c, July 2005), and the patient developed back pain. 3). However, on the surface of banana fruits, both spore germination and the formation of appresoria (specific resting spores responsible for fruit infection) were accelerated (Swinburne, 1976). Spores of Rhizopus stolonifer, which causes a watery soft rot in many fruits and vegetables, also need nutrient additives in the water in order to germinate and infect carrots (Menke et al., 1964). Generally, spores of Penicillium digitatum do not germinate in water on the surface of citrus fruit until the peel is injured (Smoot and Melvin, 1961). Commonly found in soil, food, cellulose and grains (17, 5). The NEAPP employing Ar gas had a high electron density on the order of 1015cm−3. Extract from G. lucidum also has demonstrated bacteriostatic activity against Helicobacter pylori, a causative agent for the formation of gastric ulcers and gastric cancer (Siwulski et al., 2015). These effects are shown in Figure 13. Some individuals may experience asthma symptoms or allergic reactions, while others may … Gelfand MS, Cole FH, Baskin RC: Invasive pulmonary penicilliosis: successful therapy with amphotericin B. The antagonistic yeast, Pichia guilliermondii, which is effective in controlling a wide variety of postharvest diseases in citrus fruits, apples and peaches, has been shown to induce enhanced levels of phenylalanine ammonia lyase (PAL) in citrus fruit peel (Wisniewski and Wilson, 1992), indicating the induction of a defensive response. 2). Passalora personata also can be parasitized by Cladosporiella cercosporicola (Esquivel-R. 1984). Google Scholar. Hawksworth (1981a) gives a long list of additional mycoparasites growing on conidial fungi. On the other hand, a synthetic mixture of limonene, the major terpene in the wounded fruit atmosphere, with acetaldehyde, ethanol and CO2, at concentrations similar to those measured in the atmosphere around wounded oranges, stimulated spore germination on water agar to the same degree as the natural mixture of volatiles. PubMed  Antigen-specific precipitating antibodies to Aspergillus flavus and Penicillium digitatum in the patient’s serum (a) were found by Ouchterlony double immunodiffusion testing with A. flavus and P. digitatum antigens. Ablation is an instantaneous physical removal process of debris on fruit surfaces due to the absorption and charging of the UV energy by the materials covering or adsorbed on the surface. Another common postharvest problem of citrus is sour rot, caused by the yeastlike fungus, Geotrichum candidum. Inhibition of Penicillium digitatum and Penicillium italicum by Hydroxypropyl Methylcellulose−Lipid Edible Composite Films Containing Food Additives with Antifungal Properties. However, when a comparable amount of isolated lemon peel oil was topically applied to the washed wounds, 92% of the inoculated wound sites did develop complete green mold symptoms (Arimoto et al., 1995). Penicillium digitatum In humans there is cross-reactivity to Aspergillus and Penicillium: most sera from patients with precipitins against Penicillium have precipitins against Aspergillus [7]. If you have a mold allergy, your immune system overreacts when you breathe in mold spores. Biocontrol, that is, the use of microorganisms to inhibit plant pests, offers in this ambit an attractive option to chemical pesticides.8, Not only fungi, however, but numerous microorganisms have been identified that suppress plant pathologies both in the laboratory and in field experiments, but only few of these agents are effective over a broad range of conditions. : The Royal Mushroom for High-Altitude Ailments, Management of High Altitude Pathophysiology, NOVEL APPROACHES FOR ENHANCING HOST RESISTANCE, International Journal of Food Microbiology. Sphaeronaemella helvellae, Trichoderma viride, Exobasidiellum species, and others (Vakili 1985) are efficient antagonists of pathogens, such as Fusarium verticillioides (synonym F. moniliforme sensu stricto), Cochliobolus (Helminthosporium) carbonum, and Colletotrichum graminicola involved in stalk rot of corn. In April 2005, our patient had precipitins against both P. digitatum and A. flavus, but we did not find any P. digitatum or A. flavus in sputum cultures or in bronchoalveolar lavage fluids. Alternaria species can cause black center rot of oranges and mandarins. In a recent study, Vazirian et al. Searching for the reason for this phenomenon, Eckert and Ratnayake (1994) found that a mixture of volatiles evaporating from the abrasions of wounded oranges were capable of accelerating or inducing germination of P. digitatum spores on water agar as well as within an injury of the rind. Fungal conidia that accumulate in water condensate on citrus fruits can also be induced to germinate by volatile compounds emanating from adjacent wounds. The development of the CO-sensitive Monilinia fructicola in peaches was completely inhibited in cold storage by the addition of CO to a low-O2 atmosphere (4%); however, a normal rate of rot development was resumed once the fruits were transferred to air at 20°C (Kader et al., 1982). Gas chromatogram of volatile organic compounds in the atmosphere surrounding wounded oranges. The fruiting structures (penicilli) of D’Antonio D, Violante B, Farina C, Sacco R, Angelucci D, Masciulli M, Iacone A, Romano F: Necrotizing pneumonia caused by Penicillium chrysogenum. Figure 3. The ability of various antagonistic microorganisms to act as alternatives to systemic fungicides and control postharvest diseases may be connected with their ability to produce and secrete antibiotic substances, or their ability to injure the pathogen directly. Penicillium digitatum is a plant pathogen that commonly causes a postharvest fungal disease of citrus called green mould [1]; it very rarely causes systemic mycosis in humans [3]. The fungicide sensitivity of 166 isolates to imazalil (IMZ), thiabendazole (TBZ), sodium ortho-phenylphenate (SOPP), and pyrimethanil (PYR) were determined. AS performed the tests for antigen-specific precipitating antibodies to A. flavus and P. digitatum in the patient’s serum. These species grow rapidly at 20–25 °C but very slowly below 5 °C or above 30 °C. Figure 12. A.D. Hocking, in Encyclopedia of Food Microbiology (Second Edition), 2014. Management of crop health is in fact essential to agriculture. The disinfection effectiveness of high-power PUVC combined with diffuse all- direction exposure fields can be summarized in a few selected examples from laboratory experimentation. Penicillium, a genus of ascomycetous fungi, has a long history of interaction with mankind; sometimes beneficial and sometimes harmful, the genus Penicillium contains over 300 species and remains poorly understood by the general public despite its widespread medical use. A correlation was also found between the sugar contents of nectarine and plum fruits and their susceptibility to Botrytis cinerea infection (Fourie and Holz, 1998); this finding will be discussed below in regard to enhanced susceptibility to decay during the ripening stage.
