A number of tris(2-hydroxyethyl)ammonium arylchalcogenylacetates ArYCH2CO2–• •HN+(CH2CH2OH)3 (1—4) (Ar = aryl; Y = O, S, SO2) were synthesized. Their structure was established by IR and 1H, 13C, 15N NMR spectroscopy. The influence of compounds 1—4 on the growth and development of yeast fungi Saccharomyces cerevisiae was studied. Compounds 1—4 were found to be efficient, safe, and available synthetic stimulants of these processes. The use of compounds 1—4 in low concentrations (from 10–8 to 10–4 wt.%, depending on the time of cultivation, concentration, and the anion type) reduced the lag-phases of development and increased the generation rate of yeast cells by 2—5 times. The amount of yeast cells increased by 2—3 times, while the content of protein in the biomass increased by 13—15%. The fermentation of sugar- and starch-containing raw material with yeast Saccharomyces cerevisiae increased the yield of ethyl alcohol (biofuel) by 5—9%.
合成了一些三(2-羟乙基)芳基钙酰基乙酸铵 ArYCH2CO2-- -HN+(CH2CH2OH)3 (1-4)(Ar = 芳基;Y = O、S、SO2)。通过红外光谱和 1H、13C、15N NMR 光谱确定了它们的结构。研究了化合物 1-4 对酵母真菌酿酒酵母生长发育的影响。研究发现,化合物 1-4 是这些过程中高效、安全和可用的合成刺激剂。低浓度(10-8 至 10-4 wt.%,取决于培养时间、浓度和阴离子类型)使用化合物 1-4 可减少发育滞后期,并将酵母细胞的生成率提高 2-5 倍。酵母细胞的数量增加了 2-3 倍,而生物质中的蛋白质含量增加了 13-15%。用酿酒酵母发酵含糖和淀粉的原料,可使乙醇(生物燃料)的产量提高 5-9%。
