Manganese interferes strongly with most chemical methods of biomass determination. However, the biomass of manganese-encrusted Sphaerotilus discophorus can be determined after removal of the MnO2 with trichloroacetic acid and oxalic acid. Evidence which indicates that manganese inhibits the heterotrophic growth of S. discophorus and that the cells only oxidize manganese late in the growth curve is presented.
锰对大多数生物量测定的化学方法有强烈干扰。然而,在用三氯乙酸和草酸去除二氧化锰后,可以测定被锰包裹的盘状球衣菌的生物量。文中给出了证据,表明锰会抑制盘状球衣菌的异养生长,且细胞仅在生长曲线后期才氧化锰。
