Two species of dairy streptococci, Streptococcus waius and Streptococcus macedonicus, were originally characterized by 16S-23S intergenic spacer sequence analysis, random amplified polymorphic DNA fingerprinting, PFGE analysis and DNA-DNA reassociation experiments. All genetic data suggested that S. waius strains belong to the previously described species S. macedonicus. Likewise, the phenotypi...
Prokaryotic class I release factors (RFs) respond to mRNA stop codons and terminate protein synthesis. They interact with the ribosomal decoding site and the peptidyl-transferase centre bridging these 75 A distant ribosomal centres. For this an elongated RF conformation, with partially unfolded core domains II.III.IV is required, which contrasts the known compact RF crystal structures. The crys...
In the present study, effect of adding pineapple at different rates to sheep yoghurt produced using ABT-2 culture on antioxidant activity, total phenolic compound amount, and 5-hydroxymethylfurfural (HMF) content was investigated. addition, addition storage periods physicochemical analyses (total solids, fat, protein, ash, viscosity, pH, titratable acidity values), growth probiotic cultures (St...
To develop a probiotic dietary adjunct, soymilk fermented with various combinations of lactic acid bacteria (Streptococcus thermophilus and Lactobacillus acidophilus) and bifidobacteria (Bifidobacterium longum and Bifidobacterium infantis) was subjected to freeze-drying and spray-drying. Survival of the starter organisms during the drying process, subsequent rehydration at different temperature...
The fatty acid composition of Thermus spp., including T. aquaticus ATCC 25104, T. thermophilus DSM 579, T. flavus DSM 674, and seven wild strains was examined. Organisms were tested at a minimum of either 35, 40, or 45 degrees C and at an optimum of 60 or 70 degrees C. Total fatty acid content per dry weight of cells varied between 1.2 and 3.7%, and the quantity of fatty acids was higher at the...
