Extracellular accumulation of pyrroles in bacterial cultures.

Aerobacter aerogenes, Paracolobactrum aerogenoides, Spirillum serpens, and gelatinous strains of Chromobacterium violaceum produced an extracellular, ether-soluble, Ehrlich-positive substance when grown in media prepared with gelatin hydrolysate. The substance has been tentatively identified as pyrrole-2-carboxylic acid. Both hydroxy-l-proline and allo-d-hydroxyproline have been shown to be pre...

Staling in bacterial cultures.

When a strain of bacteria is streaked on a nutrient agar or gelatin medium containing a large number of its own viable cells, no growth appears even after long incubation. Eijkman (1904) and Powers and Levine (1937) suggested that this phenomenon of "staling" was due to specific, autoinhibitory substances and that it might serve as a basis for selective and differential techniques in determinat...

Extracellular enzyme activity in anaerobic bacterial cultures: evidence of pullulanase activity among mesophilic marine bacteria.

The extracellular enzymatic activity of a mixed culture of anaerobic marine bacteria enriched on pullulan [alpha(1,6)-linked maltotriose units] was directly assessed with a combination of gel permeation chromatography (GPC) and nuclear magnetic resonance spectroscopy (NMR). Hydrolysis products of pullulan were separated by GPC into three fractions with molecular weights of > or = 10,000, approx...

Maintenance of Bacterial Cultures

^ In most laboratories in the North American Continent and in England, the older methods of Maintaining bacterial cultures by constant subculturing in suitable media have of recent years been largely superseded by the method of rapid freezing and dehydration in vacuo. As early as 1896, Martin suggested the possibility and Procedure involved in the preservation of guinea-pig complement in the dr...

Evaluation of thermal-stress on the accumulation of podophyllotoxin in shoot in vitro cultures of Linum persicum

Linum persicum is an endangered plant native to Iran, from Linaceae family. Phytochemical analysis has shown that L. persicum in vitro cultures contain podophyllotoxin (PTOX), the pharmacological precursor for anticancer drugs such as etoposide, etopophos, and teniposide. Shoot culture of L. persicum was established from callus cultures in MS medium containing GA...
