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...
متن کاملAdaptations 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...
متن کاملGrowth 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...
متن کاملX-ray crystal structure of human acidic fibroblast growth factor.
Fibroblast growth factors (FGFs) are mitogenic and chemotactic agents for a wide variety of cell types and play a primary role in the regulation of angiogenesis. Angiogenesis is involved in a variety of critical physiological events including organogenesis, wound healing, ischemic collateral circulation, and solid tumor growth. High-resolution structural information is key to understanding the ...
متن کاملX-ray crystallographic studies on murine nerve growth factor.
The largest and best characterised family of neurotrophic growth factors is that of nerve growth factor (NGF) and its relatives. In order to understand the relation of structure and function, we have undertaken X-ray analyses of murine NGF. The active component beta-NGF crystallises as hexagonal bipyramids that give good X-ray diffraction data using a synchrotron to 2.3A resolution. We have pre...
