Streptomyces lavendulae and Streptomyces venezuelae.
With the growing economic significance of some Streptomyces species, the necessity of establishing their precise characteristies in well-defined specific terms becomes of great theoretical and practical importance (Waksman, 1957). The purpose of this paper is to present a comparative study of the main morphological, physiological, and biochemical characteristics of cultures belonging to the Str...
متن کاملThe incorporation of carboxyl and bicarbonate carbon into glutamic acid by the rat.
The isotope pattern found in rat liver glycogen following administration of a variety of carbon-labeled compounds has been used by Wood and his coworkers (l-6) in studies concerning carbon metabolism. Experiments of a similar nature involving glutamic acid as the target molecule will be described in this paper. Its relative abundance, ease of isolation, and interconversion in ti~o with cY-ketog...
متن کاملStudies on Streptomyces lavendulae.
Since the isolation of streptothricin by Waksman and Woodruff in 1942 from a strain of Streptomyces lavendulae, numerous reports have appeared concerning the ability of different actinomycetes to produce this antibiotic or closely related compounds. In most of the antibiotic screening programs, streptothricin and streptothricinlike substances are among the first to be commonly encountered as pr...
متن کاملThe incorporation of the carboxyl carbon from acetate into cholesterol by rat liver homogenates.
It is well known that the digitonin precipitate from the non-saponifiable fraction of tissue lipides contains substances other than cholesterol. The importance of this fact for isotopic studies of cholesterol synthesis has been emphasized by Schwenk and Werthessen (1). Working with C14-labeled material synthesized from acetate by organ perfusions, they have shown that the cholesterol is accompa...
متن کاملIncorporation of sarcosine into the actinomycins synthesized by Streptomyces antibioticus.
Sarcosine is an amino acid apparently not widely distributed in Nature. As a free amino acid, sarcosine has been demonstrated in the radial caeca of the starfish Astropecten aurantiacus (Kossel & Edlbacher, 1915), in the muscles of Elasmobranchii (Tarr, 1958) and in the reindeer moss, Cladonia itlvatica (Linko, Alfthan, Miettinen & Virtanen, 1953). Sarcosine has been found bound in peptides in ...
