摘要:
The present invention relates to bacterial strains, capable of utilizing glycerol as a carbon source for the fermentative production of succinic acid, wherein said strains are genetically modified so that they comprise a deregulation of their endogenous pyruvate-formate-lyase enzyme activity, as well as to methods of producing organic acids, in particular succinic acid, by making use of such microorganism. The present invention also relates to the downstream processing of the produced organic acids by cation exchange chromatography.
摘要:
Methods for the controlled activation of the reuterin-production machinery of Lactobacillus reuteri by adding glycerol and other substances during the manufacture of cell-cultures and keeping the produced reuterin in the bacterial cell during preservation and storage. In particular this invention relates to the manufacture of large amounts of L. reuteri that are loaded with reuterin, and the use of such loaded bacteria for applications such as prevention and treatment of diseases, for food applications and the like.
摘要:
The invention provides methods of cultivating oil-bearing microbes using cellulosic material. Also provided are microorganisms containing one or more exogenous genes that facilitate the use of cellulosic materials as a feedstock. Also provided are microorganisms and methods for manufacturing non-alcohol-based fuels and fuel feedstocks through a process of converting cellulosic materials into oils.
摘要:
Embodiments of the invention relate to the enzymatic conversion of bioderived feedstocks to commercially valuable chemicals. The enzymatic conversions of the embodiments of the invention offer the potential for lower cost routes to these value-added chemicals. Some of the chemicals that are useful include nylon intermediates such as caprolactam, adipic acid, 1,6-hexamethylene diamine; butanediols such as 1,4-butanediol, 1,3-butanediol, and 2,3-butanediol; butanols such as 1-butanol, and 2-butanol; succinic acid, butadiene, isoprene, and 3-hydroxypropanoic acid.
摘要:
A method of producing a stably transformed corn plant in a single container is demonstrated. This method allows for the automation of the transformation process and reduces labor, material, and ergonomic costs associated with traditional plant tissue culture systems.
摘要:
The present invention relates to novel strains of Saccharomyces that can be produced on a carbonaceous substrate which makes it possible to completely and/or partially replace the use of sugar, and to the use thereof for the production of yeast, in particular on the industrial scale. The invention also relates to a method for producing yeast of the Saccharomyces genus on a carbonaceous substrate which makes it possible to completely or partially replace the use of sugar.
摘要:
The invention is a consortium of thermophilic methanotrophic organisms in culture medium containing said consortium reproduced at temperatures of 50.degree. C. to 80.degree. C., said consortium being comprised primarily of ovoid or rod-shaped organisms. The consortium can be instilled into soil or water to degrade pollutants, especially hydrocarbons and substituted hydrocarbons.
摘要:
An apparatus is disclosed for treating lignocellulosic materials, comprising an enzymatic conversion zone adapted to enzymatically convert alcohol to aldehyde and hydrogen peroxide, a delignification zone, a device for transferring an effluent comprising aqueous hydrogen peroxide from the conversion zone to the delignification zone, a chopper for adding chopped lignocellulosic material to the delignification zone, a separator for separating solid delignified material in the delignification zone from a liquid, and a fermenter adapted to grow alcohol oxidase-producing yeast, and means for transferring alcohol oxidase from the fermenter into the conversion zone.
摘要:
Single cell protein (SCP) is produced at high yields from a novel methanol assimilating Methylomonas sp. grown at elevated temperatures in an aerobic bacterial fermentation process.
摘要:
Contaminating amounts of certain halogenated aliphatic hydrocarbons are degraded and removed from water such as drinking water and industrial waste water, by treatment of the water with a microorganism that is effective to metabolize gaseous hydrocarbons by the action of monooxygenase enzyme.
