The relationship between exopolymer's specific production, relative carbohydrate and protein content in the biofilm exopolymers of the pure and mixed Thiobacillus thioparus and Stenotrophomonas maltophilia cultures and their corrosion activity was studied. Change of growth model of investigated cultures from plankton to biofilm led to an increase of specific exopolymer's production. In the biofilm formed by T. thioparus and S. maltophilia biofilm on the low-carbon steel surface one could observe an increase of relative protein content in the exopolymer complex in comparison with those in the pure culture. The development of such biofilms stimulatied the 7-fold corrosion activity.
研究了纯培养和混合培养的嗜硫硫杆菌和嗜麦芽窄食单胞菌生物膜胞外聚合物中胞外聚合物的比产量、相对碳水化合物和蛋白质含量与其腐蚀活性之间的关系。所研究培养物从浮游生长模式转变为生物膜生长模式导致胞外聚合物比产量增加。在低碳钢表面由嗜硫硫杆菌和嗜麦芽窄食单胞菌形成的生物膜中,与纯培养相比,可观察到胞外聚合物复合物中相对蛋白质含量增加。这种生物膜的形成刺激了7倍的腐蚀活性。
