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...
متن کاملFactors affecting the accumulation of biotin by Lactobacillus arabinosus.
The problem of substrate accumulation in microbial cells has been the subject of considerable investigation in recent years. However, comparatively little is known of the conditions influencing the accumulation of vitamins into microbial cells. One might cite as examples the investigations of Oginsky (1952) with vitamin B12, of Lichstein and Ferguson (1958) with biotin, and of Wood and Hitching...
متن کاملThe influence of biotin nutrition on carbon dioxide fixation and malic enzyme formation by Lactobacillus arabinosus.
Biotin has long been impliratcld in a number of carbon dioxide fixation reactions (see Lardy and Peanasky (1) for rcvicw). Two main proposals have been made to explain its mode of action: 1. The vitamin acts as a coenzyme in carbon dioxide fixation reactions. This view was based mainly on observations on the incorporation of radioactivity from C?“oz into compounds in equilibrium with certain su...

Degradation of biotin, oxybiotin, and desthiobiotin by Lactobacillus casei. J. Bacteriol. 92:925-930. 1966.-Lactobacillus casei degrades biotin when it is present in excess to products not utilizable for growth by L. plantarum or Saccharomyc...
متن کاملCell permeability: a factor in the biotin-oleate relationship in Lactobacillus arabinosus.
Bound biotin-saturated cells were incubated in the presence of biotin and glucose (37 C, pH 7.5) with or without oleic acid, Tween 20, 40, 60, and 80, Aerosol OT, sodium dodecyl sulfate (SDS), cetyltrimethylammonium bromide, Triton X-100, Non-Ion-Ox, and Haemo-Sol. With low concentrations (up to 5 mug/ml) and short reaction times (up to 10 min), oleic acid stimulated free biotin accumulation. I...
