Penicillium species

The results showed that AgNPs were effective in eliminating infectious microorganisms on B. tuberous explants; which were identified included 4 species of fungi (Fusarium sp., Aspergillus aculeatus, Trichoderma sp. and Penicillium sp.) and 1 species of bacteria (Pseudomonas sp.). At concentrations of 200 ppm and 300 ppm, AgNPs were not only effective in disinfection but also increased the induction rate of somatic embryogenesis in flower stalk TCL explants (approximately 40.00%); a similar effect was observed in stem TCL explants at the same concentration.

Mycoflora population from soil of organic and conventional fields was investigated at different plots. The fungi were isolated by using soil dilution method. Total of six genera were obtained from 10 soil samples. On the basis of cultural and microscopic characteristics, the isolated strains were identified as Aspergillus sp. Penicillium sp., Alternaria sp., Fusarium sp., Cladosporium sp. and Gliocladium sp. Aspergillus species showed the highest percentage among the six genera.

Totally 3 different irrigated paddy field soils were collected from Thanjavur district, Tamilnadu and their physico-chemical properties and population density of mycoflora were analyzed. Among them, 2 samples were sandy clay loamy soil and 1 sample was loamy soil. The physiochemical parameters were also analysed. The population density of mycoflora was maximum (52) observed in sandy clay loamy soil at Kollakadu, minimum (33) population density was observed in loamy soil at Pathirankottai.

The naturally toxigenic fungal flora, existing in conjunction with food production is most dominated genera namely, Aspergillus, Fusarium and Penicillium and to lesser extent the Alternaria, Claviceps and Stachybotrys. More than 300 mycotoxins are known to exist in nature. The economically important species of fungi producing significant mycotoxins as: aflatoxins (AFs), citrinin (CIT), cyclopiazonic acid (CPA), fumonisins (FBs), moniliformin (MON), ochratoxin A (OTA), deoxynivalenol (DON), nivalenol (NIV), T-2 toxin (T-2), patulin (PAT) and zearalenone (ZEA).

Present investigation focusing on the post-harvest fungal pathogens, fungal diseases and economic losses of papaya fruits (Carica papaya L.). Matured, ripened and infected fruits of papaya were subjected to isolation of their associated fungal pathogens. Fruit bating method was followed for isolation of fungi from infected papaya fruits. Total 10 fungal genera and 12 species viz. Aspergillus flavus, Alternaria alternata, Alternaria sp.

Present investigation emphasizes on isolation and identification of soil fungi of banana (Musa paradisiaca L.) fields from Baramati area of Pune district of Maharashtra. The isolation of soil fungi was done by using serial dilution method and Potato Dextrose Agar (PDA) medium. Morphological characters of fungi were used for their identification. Total 22 fungal species were recorded throughout the study. The contribution of Deuteromycotina was 63.63% followed by Zygomycotina 18.18%, Ascomycotina 13.63% and Mastigomycotina 4.54%.

Otomycosis is an acute, subacute or chronic fungal infection of the external auditory canal. It is worldwide in distribution with a higher prevalence in the hot, humid, and dusty areas of the tropics and subtropics. A wide variety of fungi can cause Otomycosis. In this study, our aim was to determine the most common mode of presentation, predisposing factors, and the spectrum of fungi involved in Otomycosis. 60 Ear discharge samples were collected aseptically using two sterile cotton swabs. One swab was used for direct microscopic examination and used for fungal culture.

The tomato leaves infected with early blight recorded the highest leaf surface fungal species than non-infected leaves. In total twenty six fungal species (thirteen genera) were isolated from both diseased infected and noninfected leaf surface of tomato from seven districts of Meghalaya, following leaf impression, leaf washing and dilution plating and leaf washing and serial dilution plating methods. Among all the three methods used leaf impression method recovered the highest fungal population followed by serial dilution plating and leaf washing and dilution plating method.

Microorganisms play important roles in the recycling of agricultural wastes. Composting is the degradation of organic materials through the activities of diverse microorganisms. The compost generated by bioconversion of agro-residues offers several benefits such as enhanced soil fertility and soil health which can lead to increased agricultural productivity, improved soil biodiversity, reduced ecological risks and a healthier environment. This investigation examined the microbial community dynamics, loads and identification of microbiota at various stages of composting process.

Otomycosis is an external ear canal infection caused by various fungi. The aim of this study was to identify the fungal agents, predisposing factors and characteristics of patients. Between June 2018 to December 2018, 66 patients with clinical suspicion of otomycosis were enrolled and the samples from their external ear were examined for any mycological infection. Otomycosis was confirmed after mycological diagnosis in 60 of clinically suspected patients. Otomycosis was found to be more common among females (38) and majority in the age-group 30-40 years (34.84%).

Mycoflora and mycotoxins contamination of different cattle feed samples of north Telangana region was analysed both quantitatively and qualitatively. The feed samples were highly infested by A. flavus, A. terreus and Penicillium species. The incidence of the rest of the fungi varied with the type of sample and the place of collection. The toxigenic potential of different mycotoxigenic fungi varied with substratum. The strains of A. flavus, A. terreus and Penicillium citrinum elaborated aflatoxin, patulin, terreic acid and citrinin respectively.

Survey was conducted during 2014-15 for the isolation of mycoflora from the egg masses of Meloidogyne incognita infecting crops like tomato, brinjal, pea and ameranthus from five different locations viz., Charigaon, Alengmora, Danichopari, Namdeori and Barbheta of Jorhat and Golaghat district of Assam. The egg masses were collected and surface sterilized in 0.4 per cent sodium hypochlorite (NaOCl) for two minutes. Further these egg masses were washed thoroughly with sterile distilled water until the traces of NaOCl was removed and placed in potato dextrose agar plate.

Endophytes are novel sources of natural bioactive compounds. This study seeks endophytes that produce the anticancer enzyme L-asparaginase, to harness their potential for mass production. Four plants with anticancer properties; Cymbopogon citratus, Murraya koenigii, Oldenlandia diffusa and Pereskia bleo, were selected as host plants. L-Asparaginase-producing endophytes were detected by the formation of pink zones on agar, a result of hydrolyzes of asparagine into aspartic acid and ammonia that converts the phenol red dye indicator from yellow (acidic condition) to pink (alkaline condition).
