Growth of the methanogenic bacterium Methanoplanus endosymbiosus is dependent on the presence of ruminal fluid. Ruminal fluid could be replaced by the eluate of a rumen-derived anaerobic digester. From the eluate of the digester, a growth-stimulatory component was purified and identified as p-cresol. Authentic p-cresol supported a half-maximal growth rate of the organism at 50 nM concentration.
产甲烷菌 Methanoplanus endosymbiosus 的生长依赖于瘤胃液的存在。瘤胃液可以被来源于瘤胃的厌氧消化器的洗脱液所替代。从消化器的洗脱液中,纯化出一种具有生长刺激作用的成分,并鉴定为对甲酚。纯对甲酚在 50 nM 浓度下支持该生物的半最大生长速率。
