两个新的产甲烷球菌分离，从单独的沉积物富集使用一个定义的合成生长培养基。淡水产甲烷菌M. olentangyi，sp. nov.，从哥伦布，俄亥俄州[USA]的Olentangy河沉积物中分离。这种生物是一种不运动的不规则球菌，它从CO2和H2中产生甲烷，并需要乙酸盐来生长。海洋产甲烷菌M.三角洲，sp. nov.，分离自墨西哥湾沉积物，是一种不运动的不规则球菌，生长在CO2 + H2或甲酸盐上。分离物DNA的鸟嘌呤加胞嘧啶含量分别为54.4和40.5摩尔%。
Two new methane-producing cocci were isolated from separate sediment enrichments using a defined synthetic growth medium. A freshwater methanogen, M. olentangyi, sp. nov., was isolated from Olentangy River sediment, Columbus, Ohio [USA]. The organism was a non-motile, irregular coccus that produced methane from CO2 plus H2 and required acetate for growth. A marine methanogen, M. deltae, sp. nov., was isolated from Gulf of Mexico sediments and was a non-motile, irregular coccus that grew on CO2 plus H2, or on formate. The guanine-plus-cytosine content of the DNA of the isolates was 54.4 and 40.5 mol %, respectively.
