研究结果表明，外源生长因子（维生素Ｂ１２、ｄ－生物素、５－磷酸－吡哆醛、叶酸、原黄素、核黄素）的加入可以使Ｍｅｔｈｙｌｏｓｉｎｕｓｔｒｉｃｈｏｓｐｏｒｉｕｍ３０１１菌的生长量增加．但添加生物素、吡哆醛和叶酸抑制甲烷单加氧酶和可溶性甲烷单加氧酶酶活性，而维生素Ｂ１２、核黄素和原黄素则明显促进甲烷单加氧酶和可溶性甲烷单加氧酶酶活性，可使甲烷单加氧酶和可溶性甲烷单加氧酶酶活性分别提高４０％左右和１５％－４０％，同时甲烷单加氧酶操作稳定性和贮存稳定性也明显提高１－２倍．
The results showed that the growth of Methylosinustrichosporium 3011 could be increased by the addition of exogenous growth factors (vitamin B12, d-biotin, 5-phospho-pyridoxal, folic acid, protoflavin, riboflavin) However, addition of biotin, pyridoxal and folic acid inhibited the activities of methane monooxygenase and soluble methane monooxygenase, while vitamin B12, riboflavin and protoflavin significantly promoted methane monooxygenase and soluble methane monooxygenase Enzyme activity can increase the activity of methane monooxygenase and soluble methane monooxygenase by about 40% and 15% -40% respectively, and meanwhile the operation stability and storage stability of methane monooxygenase are obviously improved by 1-2 Times
