GROWTH FACTOR REQUIREMENTS OF HALOPHILIC BACTERIA

Growth factor requirements of halophilic bacteria.

Despite the wide interest in halophilic bacteria for practical and scientific reasons, very little has been done on their organic nutritional requirements, although their inorganic requirements have received considerable attention (Robinson, 1950; Schoop, 1935). Various complex media utilizing fish infusions (Gibbons, 1936; Harrison and Kennedy, 1922; Lochhead, 1934), beef and yeast extracts or...

Growth Factor Requirements of the Root Nodule Bacteria.

It is known that yeast or plant extracts markedly stimulate the growth of the root nodule organism in media of purified ingredients. An essential growth factor or superior source of nitrogen has been invoked to explain the results, but neither theory has a broad experimental basis. The results of Allyn and Baldwin (1930) suggest that the extracts may affect favorably the oxidation-reduction pot...

Adaptations in growth factor requirements for lactic acid bacteria.

Adaptive processes in bacteria, whereby growth of organisms in deficient or drug-enriched media can be initiated through the production of new or latent enzyme systems, have been widely described. Reviews on this subject by Karstrom (1938), Dubos (1940), and Monod (1947) have provided examples of adaptation in bacterial carbohydrases and proteases, in enzymes of fermentation and glycolysis, and...

Osmoregulation in Halophilic Bacteria

Isolation of some bacteria for halophilic microbiome of Urmia Lake

Urmia Lake is the largest lake in the Iranian plateau and the second largest Salt Lake in the world. This study was conducted to identify hypersaline bacteria in the lake through the screening with molecular markers. For the molecular study of the bacterial microbiome of the lake, samples were collected from water, sludge and soil of the different parts of the lake during different seasons of 2...
