通过对甲烷菌E494、874和3009；嗜热分支杆菌111p、112p和119p；黄色分支杆菌57v和12b；红色甲基单胞菌100；红色甲基单胞菌OV3b、OV5b和4e、孢子菌5、12、A20d和90v；以及微小甲基杆菌OVVP的研究，筛选出产生胞外多糖(EPS)和以甲烷为唯一碳源的细菌：甲基球菌E494、874和3009；嗜热分支杆菌111P、112P和119P；与丝氨酸循环的细菌相比，以单磷酸核酮糖同化氯化合物的中间嗜甲烷菌合成EPS的活性更高。研究了恒化器培养过程中甲烷氧化菌合成EPS的动态。
Bacteria that produce exopolysaccharides (EPS) and use methane as the only source of carbon were selected by studying a collection of methanotroph strains: Methylococcus capsulatus E 494, 874, and 3009; M. thermophils 111p, 112p, and 119p: Methylobacter ucrainicus 159 and 161; M. luteus 57v and 12b; Methylobacter sp, 100; Methylomonas rubra 15 sh and SK-32; Methylosinus trichosporium OV3b, OV5b, and 4e, M. sporium 5,12, A20d, and 90v; and Methylocystis parvus OVVP. Mesophilic methanotroph strains with the ribulose monophosphate way of Cl-compound assimilation synthesized EPS more actively than bacteria operating the serine cycle. The dynamics of EPS synthesis by methanotrophs during chemostat cultivation was studied.
