Elemental analysis of vitamin-free casamino acids.
The elemental composition of three lots of vitamin-free Casamino Acids (Difco) was determined using X-ray fluorescence, atomic absorption, and colorimetric techniques.
Addition of Tween 80 to biotin assay medium containing acid-hydrolyzed casein as the amino acid source caused marked growth of Lactobacillus plantarum ATCC 8014 in the absence of added biotin. This growth-promoting activity could be eliminated by treating the "vitamin-free" Casamino Acids (Difco) with activated charcoal (Darco G-60) at pH 3.5 for 30 to 60 min. Incorporation of Tween 80 and char...متن کامل
Desulfovibrio aminophilus sp. nov., a novel amino acid degrading and sulfate reducing bacterium from an anaerobic dairy wastewater lagoon.
A mesophilic strain of sulfate-reducing bacterium, designated ALA-3T (T = type strain), was isolated from an anaerobic lagoon of a dairy wastewater treatment plant. The curved, Gram-negative, non-sporeforming cells (0.2 x 3.0-4.0 microns) existed singly or in chains, and were motile by single polar flagella. Optimum growth occurred at 35 degrees C and pH 7.5 on a medium containing lactate and s...متن کامل
Changes in Serum Levels of FABP4 and HsCRP after Administration of Omega-3 Fatty Acids Separately or + Vitamin E in Patients with Coronary Artery Disease
Background and purpose: Inflammatory markers of A-FABP and HsCRP play an important role in progression of cardiovascular disease. Anti-inflammatory and anti-platelet aggregation effects of omega-3 fatty acids are known. The aim of this study was to investigate the effects of omega-3 and omega-3+ vitamin E supplements on serum levels of these inflammatory markers. Materials and methods: This d...متن کامل
Saccharomyces carlsbergensis 4228 (ATCC 9080) was cultivated for 24 hours in four different media containing 0, 50, 150 and 500ƒÊg of myo-inositol per 20ml. The growth of the yeast and the specific activity of pyruvate decarboxylase extracted from the respective cell preparations were found to be proportional to the amount of inositol in the medium. The level of acetoin in the culture medium de...متن کامل
Cell-free extracts of Bacillus licheniformis and B. cereus were found to contain high specific activities of nicotinamide adenine dinucleotide phosphate (NADP)-dependent-l-glutamate dehydrogenase [EC 220.127.116.11; l-glutamate: NADP oxidoreductase (deaminating)]. Maximum specific activities were found in extracts of cells during the late exponential phase of growth when ammonium ion served as the sol...متن کامل
