Extracellular L-Glutaminase Production By Marine Bacteria

Four species of bacteria which included Pseudomonas fluorescens, Vibrio cho!erae and Vibrio costicola were observed to produce glutaminase both as extracellular and intracellular fractions. Comparatively both the fractions were higher in mineral media supplemented with 1% glutamine than in nutrient broth added with or without glutamine. Extracellular glutaminase production was about 2.6-6.8 times greater than the intracellular production by all the tested strains
