SCREENING METHOD FOR EFFICIENTLY OBTAINING USEFUL MICROBIAL STRAINS FROM MICROBIAL SAMPLE OBTAINED FROM NATURAL ENVIRONMENT AND REAGENT AND SCREENING KIT TO BE USED THEREFOR

摘要

A screening method for efficiently obtaining useful microbial strains from a sample comprises a first step of inoculating a culture medium with the sample potentially containing multiple microbial cells to culture the sample in the presence of a cell enlarger; a second step of introducing an esterase substrate fluorescent stain into the culture medium; a third step of isolating enlarged microbial cells stained in the second step according to a micromanipulation method to produce multiple culture media for establishment each inoculated with a single microbial cell; a fourth step of culturing the microbial cell in each of the culture media for establishment; and a fifth step of selecting culture media for establishment, in which cell proliferation has been confirmed, among the multiple culture media for establishment cultured in the fourth step.
