Viability of Candida shehatae in D-xylose fermentations with added ethanol.
Cell viability, as measured by plate counts, was significantly lower in all experiments (with or without ethanol addition) compared with the viability measurements by methylene blue staining, which provided a more sensitive measure of the toxic effects of added ethanol and long-term anaerobiosis on C. shehatae.

Exploration and screening of oxygen reducing potential in cytoplasmic membrane fragments of Escherichia coli and Salmonella sp.
Partially purified cytoplasmic membrane fragments derived from 24 hours old cultures of poultry isolates of Escherichia coli and Salmonella sp. were screened for presence of active oxyrase. At 37°CExpand

Microbial biotransformation of Glycyrrhizinic acid into 18-beta Glycyrrhetinic Acid (GA) was achieved using Escherichia coli MTCC 1652 whole cell using entrapment method and under optimized condition the immobilized cell produces 58.663 microg per mL of GA in licorice root extract. Expand
Effect of incubation media on the recovery of Escherichia coli K12 heated at 52 degrees C.
The exposure of exponentially grown Escherichia coli K12 to 52 degrees C for 30 min in Tris/Mg2+ buffer resulted in a considerable loss of viability when plated on tryptone agar, but after incubation for 2 h intryptone broth at 37 degrees C, the bacteria regained their resistance to u.v. and mitomycin C and tolerance to high salt medium.
