Determination of niacin in orange juice with lyophilized Lactobacillus arabinosus ATCC 8014.

The determination of niacin in orange juice with lyophilized Lactobacillus arabinosus ATCC 8014 has the advantage over the usual method in eliminating the delay caused by the necessity of cultivating cells of L. arabinosus for the inoculum and also in eliminating the periodical cultivation on agar slopes.

Biotin 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...

In vitro antagonistic effects of Lactobacillus acidophilus PTCC 1643 (DSM 20079) and Lactobacillus plantarum PTCC 1058 (ATCC 8014) against isolated bacteria from Urinary Tract Infections

Lactic acid bacteria (LAB) are gram positive and non- spore forming bacteria that can produce some special substances for growth inhibition of pathogenic, non-pathogenic and food spoilage bacteria. The aim of this study was to determine the inhibitory effects of Lactobacillus acidophilus PTCC1643 (DSM 20079) and Lactobacillus plantarum PTCC 1058 (ATCC 8014) cultural supernatants against urinary...

Amino 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...

Isoglutamine and the growth of Lactobacillus arabinosus.

The esential role of -glutamine in microbial nutrition and metabolism has been well established (Waelsch, 1952). Recently Ayengar et al. (1951) have described in detail the stimulating effect of the amide on the utilization of i-glutamic acid by Lactobacillus arabinosus. However, almost no published data exist which deal with the influence of iisoglutamine on bacterial growth. We wish to descri...
