Studies on bacterial esterases

A new species of Planococcus, P. kocurii isolated from fish, frozen foods, and fish curing brine.

“…Hydrolysis of gelatin was tested in stab cultures by using 12 % gelatin PY medium at 20 and 30°C. Hydrolysis of Tween-80 was determined by the method of SIERRA (28). Hydrolysis of esculin was examined in PY broth supplemented with 0.01 esculin and 0.05 % ferric citrate.…”

Characteristics of extracellular protein production by a plasmidless derivative of Staphylococcus simulans biovar staphylolyticus

“…Lysostaphin endopeptidase, hexosaminidase (endo-/3-N-acetylglucosaminidase), sulphydryl protease, /3-1actamase, heat-stable nuclease, phosphatase, and hemolysin were detected as previously described [5,11,12]. Lipase activity was detected on Sierra's medium [13] containing 1% (v/v) Tween 80.…”

Isolation of a Collagenolytic Gram Negative Yellow Pigmented Bacterium

“…Other tests follow published methods and included: amino acid degradation,S) attack on carbohydrates (Hugh and Leifson, 1953), temperature, pH and salinity ranges,6) DNAse production 7 ) and Tween hydrolysis. 8 ) Maintenance ofcultures. The isolated strains were grown and conserved in tubes containing tryptone soya agar (Merieux).…”
