The intracellular teichoic acid from Lactobacillus arabinosus 17-5.
It has been shown that extracts of certain bacteria contain both glycerol teichoic acid and ribitol teichoic acid, although the walls of these organisms contain only the ribitol compounds (Armstrong, Baddiley, Buchanan, Carss & Greenberg, 1958). The conclusion that glycerol teichoic acids occur in an unspecified region beneath the wall was substantiated in a more extensive survey (Baddiley & Da...
متن کاملGlutamic acid racemase from Lactobacillus arabinosus.
The existence of a glutamic acid racemase activity in Lactobacillus arabinosus has been reported by Narrod and Wood (1) and by Ayengar and Roberts (2). As has been pointed out by Meister (3) these observations with dried cell preparations would not exclude a mechanism for glutamic acid racemization in which alanine racemase is coupled with n-glutamic acid-nalanine transaminase and n-glutamic ac...
متن کاملAmino Acid Nutrition of Lactobacillus Arabinosus
The growth factors required by Lactobacillus arabinosus 17-5 have been studied extensively by Snell and Wright (I), Isbell (2), and Lewis (3). Investigation of the nitrogen requirement has been limited. Hydrolyzed casein has been found to supply the essential nitrogen when supplemented with tryptophane and cystine. Glutamic acid has been found essential (4), and quantitative levels have been de...
متن کاملBiotin and the metabolism of Lactobacillus arabinosus.
It is known that the requirement of microorganisms for certain growth factors is influenced by the nutritive medium in a manner analogous to the effect of dietary regimen of animals on their vitamin requirements. In this connection it was found by Williams and Fieger (1) that oleic acid could substitute for biotin in the growth of Lactobacillus casei under their experimental conditions. Axelrod...
متن کاملThe synthesis of cozymase from nicotinic acid and its derivatives by Lactobacillus arabinosus 17-5.
to leave a phenol-insoluble mucoid. This contains a substance with the characteristics of a mucopolysaccharide-protein complex. 5. The water-soluble mucoids contain a complex which is formed by interaction between the phenolinsoluble mucoids and a water-soluble protein of the cornea. 6. The acid mucopolysaccharide can be prepared free from protein by incubation with trypsin. Galactose, glucosam...
