The biochemical behaviour of four commercial strains of Saccharomyces cerevisiae was studied in the presence of calcium ions, acrylamide and bisacrylamide. Calcium ions at a concentration of 300 microM induced an increase of NAD(P)+ reduction in commercial Turkish and American strains, while in Chilean and Brazilian commercial strains, it diminished NAD(P)+ reduction. On the other hand, polyacrylamide monomers (acrylamide and bisacrylamide) induced a decrease of NAD(P)+ reduction in all strains studied in this paper. When membrane potential (delta psi) and oxygen consumption were measured in the presence of polyacrylamide monomers, a decrease of both was observed in all strains studied.
在存在钙离子、丙烯酰胺和双丙烯酰胺的情况下,研究了四种商业酿酒酵母菌株的生化行为。浓度为300微摩尔的钙离子会导致土耳其和美国商业菌株中NAD(P)+还原增加,而在智利和巴西商业菌株中,它会减少NAD(P)+还原。另一方面,聚丙烯酰胺单体(丙烯酰胺和双丙烯酰胺)会导致本文研究的所有菌株中NAD(P)+还原减少。当在存在聚丙烯酰胺单体的情况下测量膜电位(Δψ)和氧气消耗时,在所研究的所有菌株中均观察到两者都降低。
