In this researchsaccharomyces cerevisiae (baker’s yeast) was used as a cheap, readily accessible, selective, efficient, and green bio-catalyst in a chemo selective reduction of carbonyl group to hydroxyl group. In this green procedure three substrates e.g. (3-(3-nitrophenyl)aziridin-2-yl)-1-phenyl-methanone, pyruvate ester, and 2-acetyl-γ-butyrolactone were r...

damping-off disease of cucumber caused by soil-born fungi pythium aphanidermatum is one of the most destructive diseases of cucumber. in this research, the effect of three bio-fertilizers including; nitroxin, mycorrhiza and vermicompost in single and combined form on induced resistance and yield components in greenhouse cucumber (es-2862) infected with damping-off disease was investigated. thes...
