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
