the aim of this study was to evaluate the performances of methods such as sequencing of the internal transcribed spacer (its) and 26s (d1/d2) regions of ribosomal dna, rflp analysis of the its region and commercial biochemical test kit for the identification of the yeasts isolated during spontaneous fermentation of fresh crushed pineapple juice. the experiments were conducted in thailand and au...

Abstract To gain an insight into fungal sooty mould communities on leaves of trees and shrubs in the tropics temperate regions, 47 biofilms Mata Atlântica rainforest relic Caatinga vegetation state Sergipe, Northeast Brazil, from Central European colline alpine zones were compared. The four sampling sites clearly differed composition their epiphyllous communities. OTUs all belonged mainly to As...

BACKGROUND Polymalic acid (PMA) is a novel polyester polymer that has been broadly used in the medical and food industries. Its monomer, L-malic acid, is also a potential C4 platform chemical. However, little is known about the mechanism of PMA biosynthesis in the yeast-like fungus, Aureobasidium pullulans. In this study, the effects of different nitrogen concentration on cell growth and PMA bi...

Yeast biosurfactants are important biotechnological products in the food industry, and they have medical and cosmeceutical applications owing to their specific modes of action, low toxicity, and applicability. Thus, we have isolated and examined biosurfactant-producing yeast for various industrial and medical applications. A rapid and simple method was developed to screen biosurfactant-producin...
