Application of low-shear modeled microgravity culture for screening of new microbes and it's evaluation

研究了低剪切模拟微重力(LSMMG)对微生物群落的影响，并评价了LSMMG培养在筛选新微生物方面的潜在应用。LSMMG培养的细胞生长速率、糖消耗速率和最终细胞浓度均高于正常重力培养。观察到三组微生物：a)LSMMG促进生长；b)LSMMG抑制生长；c)LSMMG不影响生长。LSMMG促进生长的微生物表明，其中一些与尚未分离到的微生物具有很高的相似性。LSMMG培养物可用于筛选新的微生物。

The effects of low-shear modeled microgravity (LSMMG) on a microbial community were investigated, and the potential application of LSMMG culture in the screening of new microorganisms was evaluated. The cell growth and sugar consumption rates, and final cell concentrations in LSMMG culture were higher than those of normal-gravity culture. Three groups of microorganisms were observed: a) the growth was promoted by LSMMG; b) the growth was suppressed by LSMMG; and c) the growth was not affected by LSMMG. The microorganisms whose growth were promoted by LSMMG showed that some had high similarity with microorganisms that have not yet been isolated. The LSMMG culture is useful for screening of new microorganisms.
