Use of a strain bacterial for the production of formic acid or formate and advantages of the fermentation using this strain

摘要

The invention relates to the use, for the production of formic acid and / or formate, from a culture medium comprising a fermentable sugar, of a bacterial strain br / - with a deficiency in the transport or the metabolism of at least one fermentable sugar, & br / - comprising an active degradation route for the preceding one by the pyruvate formate lyase, & br / - able to convert most of the preceding sugar in the formic acid and / or formate, even in the presence of a non-limiting concentration of sugar). br / & it also relates to a fermentation process by culture of the said strain, in view of the transformation of a fermentable sugar in the formic acid or formate, as well as the culture media enriched with formic acid or formate thus obtained.
