چکیده

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 reduced to their corresponding reduced compounds in the presence of saccharomyces cerevisiae atambient temperature in aqueous media. it was worthy to note that ketone groups were chemo-selectively reduced, while ester and lactone groups remained unchanged. moreover, in this procedure, chemo selective bio-reduction of ketone group to hydroxyl group can be performed by coenzyme nadph in saccharomyces cerevisiae (baker’s yeast) which is recyclable in water, as a green solvent, while this recyclization cannot occur in non-aqueous systems. the structure of products was confirmed by ir and 1h nmr spectra.

Acetalization of Carbonyl Compounds by Using Al2 (HPO4)3 under Green Condition Mg HPO4

Al2(HPO4)3 was easily prepared and used as a solid acid in acetalization of carbonyl compounds at room temperature and under solvent-free conditions. The protection was done in short reaction times and in good to high isolated yields. The cheapness and availability of this reagent with easy procedure and work-up make this method attractive for the organic synthesis. Keywords—Acetalization, acid...

EVALUATION OF BLUE GREEN ALGAE GROWN UNDER DIFFERENT pH CONDITION FOR BIOFUEL PRODUCTION

Blue green algae was isolated from fresh water bodies of Allahabad region, Yamuna River, India to produce biodiesel. Based on rate of growth in cultural media and morphological characters and biomass production, 8 colonizing blue green algae isolates were selected for the further biofuel production work. To further narrow down the number of isolates, the carbonic anhydrase enzyme assay was used...
