We found that the marine yeast Debaryomyces hansenii strain C-11 (CIBNOR yeast collection, La Paz, Mexico) is highly tolerant to chlorine dioxide (ClO2), a powerful biocide agent. A direct application of this observation is the fermentation of the yeast in a nonsterile medium with an initial concentration of 0.3 mg/L of ClO2. The disinfectant helps to avoid the growth of unwanted microorganisms while allowing the development of the yeast. Because the concentration of ClO2 decreases during the fermentation, we ascribe to D. hansenii cells a "biocontrol" action that contributes to the collection of a contaminant-free yeast cell biomass.
我们发现，海洋酵母汉逊德巴利酵母菌株C-11（墨西哥拉巴斯CIBNOR酵母菌种保藏中心）对强力杀菌剂二氧化氯（ClO₂）具有高度耐受性。这一发现的直接应用是在初始浓度为0.3 mg/L ClO₂的非无菌培养基中进行酵母发酵。这种消毒剂有助于避免不需要的微生物生长，同时促进酵母生长。由于发酵过程中ClO₂浓度降低，我们认为汉逊德巴利酵母细胞具有“生物控制”作用，有助于收集无污染物的酵母细胞生物质。
