Abnormal cellular morphology associated with a vitamin B6 deficiency in Lactobacillus arabinosus.
tions and advantages of this method have been reported (Barber, J. MIilk & Food Technol., 12, 257-266, 1949), and it is well to point out here the obvious economy in incubator space, agar medium, time, and productivity. Usually, 4 to 5 ml of agar are used per tube. Samples (1 ml or some fraction thereof) aire added to the sterile, melted, and tempered agar; the tubes are agitated gently, slante...
متن کاملVitamin D Deficiency is Associated with the Metabolic Syndrome in Subjects with Type 2 Diabetes
Background and Objectives: There is convincing evidence that subjects concomitantly affected by type 2 diabetes (T2D) and metabolic syndrome (MeS) are at greater risk for cardiovascular disease (CVD). Many metabolic derangements in T2D might be attributed to poor vitamin D status. The purpose of this study was to investigate the associations among vitamin D status, MeS and glycemic status in su...
متن کاملTHE ROLE OF VITAMIN B,j IN THE SYNTHESIS OF TRYP- TOPHANE FROM INDOLE AND ANTHRANILIC ACID BY LACTOBACILLUS ARABINOSUS”
Lactobacillus arabinosus has the ability to synthesize several amino acids when adequate quantities of vitamin Bg are included in the medium (1, 2) ; however, the requirement of this organism for tryptophane is apparently not affected by the addition of vitamin 136 (2). Earlier studies showed that indole and anthranilic acid have appreciable tryptophane activity for L. arabinosus (3-7) but not ...
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 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...
