Is butanol toxic
WebThough butanol-forming bacteria generate enzymes that convert simple sugars into alcohol, butanol itself is toxic for these microbes. As a result of this inhibition by butanol, there is a low alcohol concentration in the fermenting medium. Thus, the butanol yield is reduced, and production costs have grown. WebSpecific target organs and selective toxicity have not been identified. nBA is not genotoxic and there is no concern for carcinogenic potential. nBAshowed some foetotoxicity in laboratory animals at high concentrations that were toxic to the mother, but is devoid of selective developmental toxicity.

WebButanol toxicity is one of the most significant problems in ABE fermentation. The titer of 1-butanol rarely exceeds 13 g L −1, which is considered to be a toxicity limit presumably caused by the disruption of cell membrane (Jones and Woods 1986). WebThe single-dose systemic toxicity of tert-butanol is low, but it is irritant to skin and eyes; high oral doses produce ataxia and hypoactivity and repeated exposure can induce …
