a green low-cost and reproducible yeast mediated synthesis of silver nanoparticles is reported. the synthesis is performed at room temperature. x-ray and transmission electron microscopy analyses are performed to ascertain the formation of ag nanoparticles. nanoparticles almost spherical in shape having a size of 6-20 nm are found.

This review gives an overview of different yeast strains and enzyme classes involved in yeast whole-cell biotransformations. A focus was put on the synthesis of compounds for fine chemical and API (= active pharmaceutical ingredient) production employing single or only few-step enzymatic reactions. Accounting for recent success stories in metabolic engineering, the construction and use of synth...

A saccharomyces sp. causing fermentation in Meduca asava was isolated from Maduca flowers (Maduca longifolia Macbride). The capability of the organism to cause fermentation in Drakshasava was carried out. The Saccharomyces sp. caused alcoholic fermentation and the alcoholic fermentation and the alcohol produced was almost equal in quantity to that prepared according to textual method. The chang...

Ripe banana fruit is used to isolate and identify native yeasts from the different cultivars of Musa sp. such as Champa kola, Malbhog/Sapri kola, Saiel kola, Geera kola and Jahaji kola which can be utilized for the preparation of beverages yeast. Highest mean counts of yeast were 56.3 ×103 CFU/mL in the Champa kola of Musa sp. The total 44 yeast strains were identified, comprising ascomycetes a...

Chemical surfactants are highly toxic to the environment so the Biosurfactants have paying attention by many scientists because of their low toxicity, biodegradability and ecological acceptability. The aim of this present study is to produce the Biosurfactants from Saccharomyces cerevisiae and Pseudomonas aeruginosa and to check its antimicrobial activity against several bacterial (Such as Esch...
