An inducible penicillin beta-lactamase was purified from a strain of Alcaligenes faecalis resistant to beta-lactam antibiotics. The purified enzyme preparation gave a single protein band on polyacrylamide gel electrophoresis, and its molecular weight was 29,000 based on sodium dodecyl sulfate-acrylamide gel electrophoresis. Its isoelectric point was 5.9. The enzyme more rapidly hydrolyzed penic...

Maleic hydrazide (1, 2-dihydropyridazine-3, 6dione) is an organic plant growth regulator which has found use in such varied areas as prevention of sucker formation in tobacco, prevention of sprouting of some stored vegetables, and as a herbicide. In commercial application the diethanolamine salt (diethanolammonium maleic hydrazide or diethanolammonium-1 ,2-dihydropyridazine-3, 6-dione) is often...

Biochemistry of civet coffee fermentation in the digestive tract civets until now is not fully known. This study aims to isolation, characterization and identification bacteria molecularly from civet's tract. Analysis begins with surgery obtain fluid three parts Isolation conducted by pour plate method using nutrient agar media. Single different colonies (shape, colour, margin, elevation, size)...

Alcaligenes jaecalis is capable of growing in response to simple pteridines as the sole source of nitrogen (1). Simple pteridines appear to be metabolized in this organism through the common intermediate, tetraoxypteridine (1, 2)) and cell-free extracts of the organism catalyze the conversion of tetraoxypteridine to xanthine-8-carboxylic acid (1). In these conversions the nitrogen atoms of the ...
