Abstract
:
ethanol-assimilating microorganisms were isolated from 27 soil samples. Thirty-one (26 bacteria and 5 yeasts) out of 385 isolates were found to be methylotrophs. Fungal and actinomycetes isolates did not grow on methanol as a sole carbon source. The growth parameters of yeast and bacterial isolates in shake flasks cultures widely varied from one isolate to another. The methylotrophic bacterial strains 148-16, 118-11,018-01 and 108-11 showed the highest specific growth rates, being 0.083,0.059,0.058 and 0.057 h-1 respectively. Pichia sp. 2y-17 gave a short exponential phase as compared with bacterial isolates. The methylotrophic bacterial strain 148-16 gave the highest biomass and protein productivity (113.30 and 73.88 mg/100 ml culture respectively). Effective yield of tested yeast was found to be of a low value. Microbial growth was highly affected by the high concentration of formaldehyde.
