Life History Responses and Gene Expression Profiles of the Nematode Pristionchus pacificus Cultured on Cryptococcus Yeasts.

Nematodes, the earth's most abundant metazoa are found in all ecosystems. In order to survive in diverse environments, they have evolved distinct feeding strategies and they can use different food sources. While some nematodes are specialists, including parasites of plants and animals, others such as Pristionchus pacificus are omnivorous feeders, which can live on a diet of bacteria, protozoans, fungi or yeast.

Role of ligninolytic enzymes of white rot fungi (Pleurotus spp.) grown with azo dyes.

Background: Total three Pleurotus species (P. ostreatus, P. sapidus, P.

Medicinal and antimicrobial role of the oyster culinary-medicinal mushroom Pleurotus ostreatus (higher Basidiomycetes) cultivated on banana agrowastes in India.

Oyster mushrooms, species of the genus Pleurotus, are recognized for producing secondary metabolites with important medicinal properties. Investigations were carried out to evaluate the antioxidative and antimicrobial properties of the edible mushroom Pleurotus ostreatus (MTCC142) extracts cultivated on banana agrowastes. Ethanolic extracts showed antimicrobial activities against gram-positive and gram-negative bacteria, and their in vitro antifungal activities against all fungi tested revealed a promising role.

Isolation and partial purification of erythromycin from alkaliphilic isolated from Rajkot, India.

An alkaliphilic actinomycete, BCI-1, was isolated from soil samples collected from Saurashtra University campus, Gujarat. Isolated strain was identified as based on morphological, biochemical and phylogenetic analysis. Maximum antibiotic production was obtained in media containing sucrose 2%, Yeast extract 1.

Isolation, optimization, and partial purification of amylase from Chrysosporium asperatum by submerged fermentation.

A potent fungus for amylase production, Chrysosporium asperatum, was isolated from among 30 different cultures obtained from wood samples collected in the Junagadh forest, India. All of the isolated cultures were screened for their ability to produce amylase by submerged fermentation. Among the selected cultures, C.
