The MAR indexes of hospital isolates of Pseudomonas aeruginosa were determined with reference to nine different cephalosporins suggesting their origin from a high risk source of contamination where antibiotics are often used.
Optimization of medium and cultivation conditions for L-amino acid oxidase production by Aspergillus fumigatus.
The enzyme showed enantiomerically pure amino acid formation, which has tremendous demand in industrial applications, and belong to the species Aspergillus fumigatus (designated as P13).
Production and properties of asparaginase from a new Erwinia sp.
The combination of L-arginine, L-asparagine and L-glutamine synergistically stimulated the asparaginase up to 5.8 fold.
Alcoholic fermentation by agar-immobilized yeast cells
Immobilized yeast cells in agar gel beads were used in a packed bed reactor for the production of ethanol from cane molasses at 30°C, pH 4.5 and the maximum specific ethanol productivity and specific sugar uptake rate were 0.610g ethanol/g cell and 1.275g sugar/G cell, respectively.
Microbial degradation of sulfur compounds present in coal and petroleum
Production, purification and characterization of an α-amylase produced by Saccharomycopsis fibuligera
Saccharomycopsis fibuligera ST 2 produced high levels of extracellular amylase during the stationary phase of growth, indicating the lack of catabolite repression in this organism.

The binding of thirteen Litsea derived biologically active compounds against the inflammation associated target COX (cyclo-oxygenase) -2 enzymes is illustrated.
Optimization of alkaline amylase production by thermophilic Bacillus stearothermophilus AN 002
Bacillus stearothermophilus AN 002 secreted thermostable alkaline amylase into a liquid growth medium containing 2 g/l starch and was found to be stable between pH 6.0 to 11.0.
Aspergillus fumigatus L-Amino Acid Oxidase-Two Step Purification and Characterization of the Enzyme
The first report of purification of L-aao from Aspergillus fumigatus was purified by ion exchange and gel filtration chromatographies and the enzyme has higher specificity towards hydrophobic aromatic L-amino acids namely tyrosine and phenylalanine.
Production and properties of asparaginase from a newErwinia sp.
Among the various carbon sources, mannitol was shown to be the best for production of activity and inorganic nitrogen sources were better than the organic ones.
