Abstract:
The invention is related to a method for increasing methane yield in anaerobic digesters, by adding a cellulolytic bacteria cocktail (cebac-g) prepared with rumen fluid of hornless goats, that has been developed in order to increase methane yield in a system by increasing the hydrolysis efficiency at a maximum level, in anaerobic digesters that are treating lignocellulosic waste, such as animal manure, agricultural waste, energy plants, food residue, sewage sludge, household wastewater and industrial wastewater. The invention is a method for increasing methane yield in anaerobic digesters by adding cellulolytic bacteria cocktail (cebac-g) prepared from rumen fluid of hornless goats, comprising the steps of obtaining the rumen fluid from hornless goats, obtaining specific cellulolytic bacteria cocktail by inoculation of the medium with bacteria such as Firmicutes, Clostridiaceae, Bacteroidales, Ruminococcaceae, Prevotellaceae, Lachnospiraceae, Synergi stales, Fibrobacter, Lentisphaeria, Spirochaetes and Actinobacteria.

Abstract:
Syntrophic co-cultures comprising at least two microorganisms, wherein (a) at least one of the microorganisms is a solventogen able to metabolize biomass to produce metabolic byproduct(s) therefrom, (b) at least one of the microorganisms is a microorganism different from the solventogen, wherein the microorganism different from the primary solventogen depends on the metabolites and/or the metabolism of the primary solventogen for survival and growth and is able to fix or metabolize the metabolic byproducts produced by the solventogen to produce metabolic byproduct(s) therefrom, and (c) the solventogen is able to metabolize the metabolic byproduct(s) produced by the microorganism different from the solventogen to produce further metabolic byproducts, such as liquid fuels and commodity chemicals, as well as methods for using these syntrophic co-cultures to producing such products via fermentation, are disclosed.
Abstract:
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung von Biogas in einem kombinierten Fermenter, in dessen erstem Abschnitt (2) organisches Material durch phototrophe Mikroorganismen (1) unter Verwendung von atmosphärischem Kohlenstoffdioxid und Sauerstoff hergestellt wird, welches in einem zweiten Abschnitt (4) zur Herstellung von Biomethan durch Methanbildner (5) verwendet wird. Der Fermenter wird in mehreren Modi und mit speziellem Be- und Entgasungsverfahren betrieben, so dass eine optimale Gasversorgung entsprechend der Bedürfnisse der jeweiligen Mikroorganismen und vorzugsweise auch die Aufnahme bzw. der Verbrauch von atmosphärischem Kohlenstoffdioxid gewährleistet wird.
Abstract:
The invention provides methods and systems for the production of lipid products from a gaseous substrate using a two stage fermentation process. The method comprises providing a gaseous substrate comprising CO, CO 2 or H 2 or mixtures thereof, to a first bioreactor containing a culture or one or more microorganisms, and fermenting the substrate to produce acetate. The acetate from the first bioreactor is then provided to a second bioreactor, where it is used as a substrate for fermentation to lipids by one or more microalgae.
Abstract:
The invention is directed to a method for producing an enriched diatom culture, comprising subjecting a starting culture comprising one or more diatom species to selective pressure, thus giving a competitive advantage to storage compound producing species of diatoms, by subjecting said starting culture, under non-limiting bioavailable silicon concentrations, to a cycle of alternating dark phases and light phases and providing limitation of availability of at least one essential growth nutrient in one or more of said light phases.
Abstract:
A process involving a microorganism consortium for converting at least one component in a carbon-bearing material to a different product comprising at least one hydrocarbon. In the process, a microorganism consortium is contacted with a composition that causes an increase or decrease of a relative population of at least one species of microorganism in said microorganism consortium, to enhance a yield or selectivity or alter a rate of said process. The composition may be selected from a composition that affects an intracellular pathway of said at least one species of microorganism, a composition that affects an intercellular signaling pathway that involves said at least one species of microorganism and at least one antisense RNA. Also, the microorganism consortium can be exposed to signals such as sound waves or electromagnetic signals or a condition of the environment of the microorganism consortium can be altered.
