Effect of peptone on Azotobacter morphology.
Pleomorphism in cultures of Azotobacter vinelandii was induced by addition of Difco peptone to the growth medium. Under the conditions of the study, 5% peptone gave rise to transient forms described as "fungoid cells" which were osmotically fragile. After some 48 hr of culture, they became osmotically stable and resumed a more typical morphology. It was shown that the pleomorphism-inducing prin...
متن کاملLysis of halobacteria in bacto-peptone by bile acids.
All tested strains of halophilic archaebacteria of the genera Halobacterium, Haloarcula, Haloferax, and Natronobacterium lysed in 1% Bacto-Peptone (Difco) containing 25% NaCl, whereas no lysis was observed with other strains belonging to archaebacteria of the genera Halococcus, Natronococcus, and Sulfolobus, methanogenic bacteria, and moderately halophilic eubacteria. Substances in Bacto-Pepton...
متن کاملInterference of peptone and tyrosine with the lignin peroxidase assay.
The N-unregulated white rot fungus Bjerkandera sp. strain BOS55 was cultured in 1 liter of peptone-yeast extract medium to produce lignin peroxidase (LiP). During the LiP assay, the oxidation of veratryl alcohol to veratraldehyde was inhibited due to tyrosine present in the peptone and the yeast extract.
متن کاملThe Effect of Peptone on the Peripheral Circulation
1. Injection of a solution of peptone directly into the artery of the leg of a dog is followed by an abrupt increase in leg volume. This is of short duration and is quickly followed, usually in less than (1/2) minute, by a decrease in the volume of the limb below that previous to the injection. 2. The phases of the leg volume curve bear a fairly definite relation to the changes in arterial pres...
متن کاملPostprandial Hypoglycemia
Postprandial hypoglycemia is a syndrome secondary to disorders in which hypoglycemia is manifested within 5 hours after a meal (1). It is classified into two types depending on the time of occurrence, i.e., ‘early,’ with onset within 2 hours, and ‘late,’ occurring between 3 and 5 hours after a meal. The early variety is thought to be secondary to abnormally rapid gastric emptying, whereas late ...
