Item Differences in the regulation of biosynthesis of 20- versus 22-carbon polyunsaturated fatty acids(Elsevier, 1995) Sprecher, H.W,; Baykousheva, S.P.; Luthria, D.L.; Mohammed, B.S.Item ATPase activation in Bacillus subtilis strain 168 with phospholipids(1987) Baikusheva, S; Ilieva, KItem On the phagocytosis in vitro of strains of Yersinia pseudotuberculosis after treatment with certain detergents and lipid solvents(Bulgarian Academy of Sciences, 1976) Baykousheva, S.; Veljanov, D.Reproduced from SciFinder with permission from the Chemical Abstracts Service. The addn. of Na lauryl sulfate [151-21-3] or petroleum ether to Y. pseudotuberculosis grown in a medium contg. 10% glycerol at 28° (conditions under which V and W antigens are not synthesized) significantly increased the phagocytosis of the bacterial cells by rabbit blood. The addn. of Na periodate or trypsin [9002-07-7] produced variable degrees of phagocytosis dependent on the virulence of the strains tested. The role of lipid synthesis in the restoration of phagocytosis at 28° is discussed.Item Further studies on the metabolic changes in strains of Salmonella typhimurium and Yersinia pseudotuberculosis after treatment with some detergents and lipid solvents(1977) Veljanov, D; Radoucheva, T; Baykousheva, S; Kussovski, VReproduced from SciFinder, with permission from the Chemical Abstracts Service. Incubation of S. typhimurium and Y. pseudotuberculosis in 30% petroleum ether at 37° inhibited respiration more than did 0.01-0.03% Na lauryl sulfate [151-21-3]. After a 72-h incubation in 10% glycerol [56-81-5] the respiration level returned to, or approached normal. Petroleum ether also inhibited dehydrogenase [9035-82-9] activity and glycolysis more than did Na lauryl sulfate. Incubation in glycerol also reversed this inhibition. Na lauryl sulfate completely and irreversibly inhibited phosphatase [9013-05-2] at pH 5.4 and 8.0. Petroleum ether inhibited phosphatase at pH 5.4 in Y. pseudotuberculosis and at pH 8.0 in S. typhimurium.Item Secretion of proteins by Bacillus subtilis in the presence of membrane-active agents(1987) Baykousheva, SvetlaItem Effect of cerulenin on Bacillus subtilis 168(Springer, 1987) Baykousheva, Svetla; Cherepova, Nadja; Ilieva, KonstantinaItem From the cord-factor of mycobacteria to the synthetic immunostimulants(Bulgarian Academy of Sciences, 1983) Baykousheva, SvetlaItem New concepts about phagocytosis(Bulgarian Academy of Sciences, 1979) Baykousheva, SvetlaItem Ultrastructure of Bacillus subtilis 168 treated with cerulenin(1985) Cherepova, Nadja; Baykousheva, Svetla; Ilieva, KonstantinaItem Some biological properties of bacterial lipids(1977) Baykousheva, S; Veljanov, D
