Polysaccharides synthesized by micro-organisms

Lxxxvi. Polysaccharides Synthesised by Micro-organisms Iii. the Molecular Structure of Galacto- Carolose Produced from Glucose by Penicillium

Polysaccharides synthesized by aerobic mesophilic spore-forming bacteria.

In the classification proposed by Smith, Gordon & Clark (1946) the genus Bacillus has been divided into three groups depending principally on morphological differences in the size and shape of the spores and the shape of the sporangia. Their classification and nomenclature has been used throughout this paper. The bacilli of group I are known to synthesize fructosans from sucrose; those obtained...

Utilization of S-adenosylmethionine by micro-organisms.

Shapiro, Stanley K. (Argonne National Laboratory, Argonne, Ill.). Utilization of S-adenosylmethionine by microorganisms. J. Bacteriol. 83:169-174. 1962.-Two types of mutants of Aerobacter aerogenes that utilize S-adenosylmethionine for growth are described. One type also responds to methionine, 5'methylthioadenosine, or a combination of homocysteine and S-methylmethionine. The second type of mu...

The Polysaccharides Synthesized by Strepto- Coccus Salivarius and Strepto-

In a previous paper (1) it was reported that certain non-hemolytic streptococci from the human throat are capable of synthesizing large amounts of a carbohydrate from sucrose and raffinose. These organisms seem to be similar to those studied by Oerskov and Poulsen (2). When grown on the surface of agar containing 5 per cent sucrose or raffinose, large mucoid colonies are produced which are abou...
