Abstract

Under stressful conditions, including infection with phytopathogens, plants produce various compounds that are growth activators, e.g., hydroxycinnamic acids (HAs), including ferulic acid (FA). The role of HAs in the relationship of plants and endophytic bacteria has not been studied in detail. The effect of FA at a concentration of 1.0–1000 μg/L on the reproduction and growth of the endophytic strain Bacillus subtilis 26D on agar and liquid media has been studied. It was found that FA suppressed and, at a lower concentration (0.7%), increased the size of bacterial colonies on an 1.5% agar medium. In a liquid medium, FA stimulated the multiplication of bacterial cells. It was shown that bacteria of the strain B. subtilis 26D are capable of FA destruction.

阿魏酸对内生菌枯草芽孢杆菌26D菌落生长和细胞繁殖的影响

摘要

在压力条件下，包括植物病原体感染，植物会产生各种作为生长激活剂的化合物，例如羟基肉桂酸 (HA)，包括阿魏酸 (FA)。HAs在植物与内生细菌关系中的作用尚未得到详细研究。已经研究了浓度为 1.0-1000 μg/L 的 FA 对内生菌株枯草芽孢杆菌26D 在琼脂和液体培养基上的繁殖和生长的影响。发现 FA 抑制并在较低浓度 (0.7%) 下增加了 1.5% 琼脂培养基上细菌菌落的大小。在液体培养基中，FA 刺激细菌细胞的增殖。结果表明，枯草芽孢杆菌26D菌株的细菌能够破坏 FA。
