Systems and methods for digestion of solid waste

Номер: US20120015430A1
Принадлежит: Christensen Christian B

This invention relates generally to systems and methods for digestion of solid waste that simplify solids handling. In certain embodiments, anaerobic methane extraction takes place for a period of time (e.g., from 1 to 4 weeks), after which an aerobic composting process begins in the same chamber. The organic waste remains in place and oxygen (e.g., in air) is forced into the chamber for an additional period of time (e.g., from 2 to 4 weeks). At the conclusion of the aerobic phase, the process yields a rough compost product that is stable and pathogen free. The rough compost can be further processed and blended to create high value engineered soils.

Microbially-assisted water electrolysis for improving biomethane production

Номер: US20120100590A1
Принадлежит: NATIONAL RESEARCH COUNCIL OF CANADA

A method of producing in a bioreactor a biogas rich in methane involves electrolyzing water in an aqueous medium at a voltage in a range of from 1.8 V to 12 V in the presence of electrochemically active anaerobic microorganisms that biocatalyze production of hydrogen gas, and, contacting a species of hydrogenotrophic methanogenic microorganisms with the hydrogen gas and carbon dioxide to produce methane. Volumetric power consumption is in a range of from 0.03 Wh/L R to 0.3 Wh/L R . Current density is 0.01 A/cm E 2 or lower. The voltage is sufficient to electrolyze water without destroying microbial growth. Such a method results in improved electrolysis efficiency while avoiding the use of noble metal catalysts. Further, a combination of water electrolysis with anaerobic degradation of organic matter results in increased biogas quality and in increased biogas quantity and yield. Oxidation of hydrogen sulfide contributes to the increased quality, while an increase in the rate of organic matter hydrolysis and an increase in the production of methane from hydrogen contributes to the increased quantity and yield.

Автор: Lothar Guenter
Принадлежит: DGE Dr Ing Guenther Engineering GmbH

The invention relates to a method for producing biogas or sewage gas by a multi-stage anaerobic reaction of biomass and/or sludge. Considering the disadvantages of the known prior art, a method is to be provided that leads to a higher yield of raw gas or biogas and a higher content of methane in the raw gas and enables an economically improved operating method. To this end, the reaction is carried out in the first fermentation stage (F 1 ) while maintaining a TS content of 3 to 8% and a volume load of 1 to 3 kg OTS/m 3 d. In the second fermentation stage (F 2 ), a further reaction of the solid matter phase is carried out while maintaining a TS content of 8 to 40% and a volume load of over 2 kg OTS/ m 3 d. In the second fermentation stage, the fermentation substrate is set to a TS content that is higher than the TS content of the first stage. In both fermentation stages, the reaction is carried out in the range from slightly acidic to neutral (pH value 6.5 to 8). The biogas obtained in the fermentation stages (F 1, F 2 ) is combined or removed separately and is subjected to further purification.

The present invention is directed to variant squalene synthase enzymes, including squalene synthase enzymes, and to nucleic acid molecules encoding these variant enzymes. These variant enzymes produce squalene at a lower rate than the wild-type enzyme, allowing more farnesyl pyrophosphate to be utilized for production of isoprenoid compounds, while still producing sufficient squalene to allow the cells to grow without the requirement for supplementation by sterols such as ergosterol. These variant enzymes, therefore, are highly suitable for the efficient production of isoprenoids. 1.

The present invention relates to a novel microorganism having high squalene-producing ability, and to a method for producing squalene using the microorganism.Squalene is an intermediate of sterol synthesis that has long been used throughout the world as a health food. In recent years, squalene has been found to have physiological activity, and its effects of preventing radiation-induced damage and preventing canceration of cells have become a topic of interest. Squalane, which is the reduced form of squalene, is also widely used as a humectant for cosmetics, and even as a mechanical lubricant oil and heat exchange medium.The major sources of squalene are deep-sea sharks, and in the conventional methods of extracting and purifying squalene, deep-sea shark livers are collected, the cells are pulverized in hot water, and the resulting freed oily fat is collected and purified with an adsorbent or the like. However, shark catches are extremely unstable since they are captured from the wild, and therefore prices vary due to unstable supply. In recent years, restrictions have been placed on capturing of deep-sea sharks since they have been designated as an endangered species, and from the viewpoint of protecting the natural environment, it has been desirable to develop an alternative method for producing squalene other than by extraction from deep- ...
