Surface-active substances synthesized by Rhodococcus erythropolis ІMВ Ас-5017 during co-cultivation with inducing bacteria either Bacillus subtilis BT-2 or Escherichia coli ІЕM-1 (SASI) had the higher antimicrobial and antiadhesive activities in comparison with surface-active substances synthesized in the medium without cells of inducing bacteria (SAS). Minimum inhibitory concentrations of SASI ranged from 3 to12 μg/mL and were in 4-32 times lower than the same parameter for SAS. Treatment of abiotic surfaces (ceramic, steel, and glass) with SASI decreased adhesion of bacteria Staphylococcus aureus BMC-1 or yeasts Candida albicans D-6 to the level of 10-32 % in comparison with 32-87 % after treatment of surfaces with SAS. Destruction of bacterial and yeast biofilms treated with SASI was in the range from 40 to 94 %, while it was 32-65 % in the case when SAS was used. Increasing of biological activity of surface-active substances synthesized by R. erythropolis in co-culture with inducing bacteria E. coli or B. subtilis was shown for the first time.

红球红球菌与其他菌株共培养对合成表面活性物质生物活性的影响

红球菌 ІMВ Ас-5017 在与诱导细菌共培养过程中合成的表面活性物质,枯草芽孢杆菌 BT-2 或大肠杆菌 ІЕM-1 (SASI) 与合成的表面活性物质相比具有更高的抗菌和抗粘附活性不含诱导菌细胞的培养基(SAS)。SASI 的最小抑制浓度范围为 3 至 12 μg/mL,比 SAS 的相同参数低 4-32 倍。用 SASI 处理非生物表面(陶瓷、钢和玻璃)后,金黄色葡萄球菌 BMC-1 或酵母菌白色念珠菌 D-6 的粘附降低至 10-32% 的水平,而用 SASI 处理表面后的粘附率为 32-87% SAS。用 SASI 处理的细菌和酵母生物膜的破坏在 40% 到 94% 的范围内,而在使用 SAS 的情况下为 32-65%。在与诱导细菌大肠杆菌或枯草芽孢杆菌共培养的情况下,R. erythropolis 合成的表面活性物质的生物活性增加首次被证明。
