Various organic sulfides and inorganic sulfide were studied in respect to their effect on growth and methane production of Methanobacterium strain AZ. In mineral, sulfide-free medium, cysteine regulated the specific rate of methane production (optimum concentration = 5-10(-4) mole/1). A supplement of sulfide (10(-4) mole/1) caused an additional stimulation. Coenzyme M** or glutathione could be substituted for cysteine when sulfide was present. Growth was stimulated by CoM and glutathione to the same extent as with cysteine in sulfide-containing media. The concentration of sulfide in cysteine-containing media affected the excretion of amino acids.
研究了各种有机硫化物和无机硫化物对甲烷杆菌菌株AZ生长和甲烷产生的影响。在不含硫化物的矿物质培养基中，半胱氨酸调节甲烷产生的比速率（最佳浓度 = 5×10⁻⁴摩尔/升）。添加硫化物（10⁻⁴摩尔/升）会产生额外的刺激作用。当存在硫化物时，辅酶M**或谷胱甘肽可以替代半胱氨酸。在含硫化物的培养基中，辅酶M和谷胱甘肽对生长的刺激程度与半胱氨酸相同。含半胱氨酸培养基中硫化物的浓度影响氨基酸的排泄。
