A biosolvent for cleansing surface that provides bactericidal and bacteriostatic activity such that the bacteriostatic activity continues to inhibit bacterial growth on the surface even after rinsing. The biosolvent comprises C2 to C4 alcohols and lactate esters of C2 to C4 alcohols. The bactericidal and bacteriostatic activity are especially useful for cleaning active biological surfaces and in particular for sanitizing hands.

Method for providing bactericidal and bacteriostatic activity with a biosolvent formulation

An enhanced diluent (EDIL) composition used to prepare a transportable dense crude oil composition is disclosed. An EDIL composition contains a usually used dense crude hydrocarbon diluent (DIL) plus an additive (ADD) composition that permits the amount of EDIL used in the resulting diluted transportable dense crude (EDIL:DC) to be lessened by about 20 to about 60 percent, while maintaining the viscosity and other properties of the usually used DC:DIL composition. A contemplated ADD composition is a mixture of three components, a solvent mixture, a diol and a surfactant. A contemplated EDIL composition contains about 1 to about 20 percent by weight of the ADD composition. Admixture of EDIL with a dense crude at about 80 to about 40 percent by volume of the amount of DIL usually used provides an easily transportable enhanced dense crude composition. A method of preparing a transportable dense crude composition is also disclosed.

Oxygenated solvent and surfactant for heavy crude upgrade

High conversion efficiency processes are disclosed for the anaerobic bioconversion of syngas to alcohol. The processes use bioreactors that have a non-uniform gas composition and a substantially uniform liquid composition such as deep tank bioreactors. By maintaining certain electron to carbon mole ratios in the syngas feed to the bioreactors and certain partial pressures of carbon dioxide in the off gas from the bioreactors, at least about 80 percent of the hydrogen and at least about 95 percent of the carbon monoxide in the feed can be consumed.

Integrated processes are disclosed for the anaerobic bioconversion of syngas to alcohol wherein a gas substrate of carbon monoxide, hydrogen and carbon dioxide is in contact with an aqueous menstruum that continuously contacts the gas substrate with said aqueous menstruum to produce alcohol and a depleted gas phase that is continuously withdrawn from the aqueous menstruum; continuously or intermittently and the gas substrate is made up of at least two gases having different compositions to provide an overall gas substrate having a ratio of electrons to carbon atoms in the range of about 5.2:1 to 6.8:1.

Integrated processes are disclosed for reducing the carbon foot print related to the use of non-renewable hydrocarbon gas streams for producing alcohols by anaerobic bioconversion of reformed gas. These processes combine renewable and non-renewable gas sources of hydrogen, carbon monoxide and carbon dioxide to produce alcohol. Thus the invention found a highly a practical way to make use of non-renewable carbon oxide sources while still lowering the carbon footprint of such alcohols produced thereby, especially when combined with corn ethanol production. In the case of motor fuel use, the renewable portion of the alcohol produced in this manner provides a reduction in greenhouse gases by 50% or more when compared to gasoline.

Gene sequences of key acetogenic clostridial species were sequenced and isolated. Genes of interest were identified, and functionality was established. Key genes of interest for metabolic catalyzing activity in clostridial species include a three-gene operon coding for CODH activity, a two-gene operon coding for PTA-ACK, and a novel acetyl coenzyme A reductase. The promoter regions of the two operons and the acetyl coA reductase are manipulated to increase ethanol production.

Genes encoding key catalyzing mechanisms for ethanol production from syngas fermentation

A method of operating a fermentation zone for the production of ethanol from syngas uses a crotonate-like compound to prevent or reverse the effects of butyrogen contamination. The crotonate-like compound works in continuous fermentation processes to reduce or eliminate contamination from butyrate and butanol in the syngas derived ethanol product.

Method for controlling undesirable byproducts formation caused by contaminating organisms in the production of ethanol from syngas

Ethanol and other liquid products are produced by contacting syngas components such as CO or a mixture of COand Hwith a surface of a membrane under anaerobic conditions and transferring these components into contact with a biofilm on the opposite side of the membrane. These steps provide a stable system for producing liquid products such as ethanol, butanol and other chemicals. The gas fed on the membrane's gas contact side transports through the membrane to form a biofilm of anaerobic microorganisms that converted the syngas to desired liquid products. The system can sustain production with a variety of microorganisms and membrane configurations.

Membrane supported bioreactor for conversion of syngas components to liquid products

Ethanol and other liquid products are produced from biomass using indirect gasification of the biomass to produce a syngas containing CO2, CO, H2 and methane that passes the syngas without substantial removal of the methane to a fermentation zone for the conversion of the CO and CO2 and H2 to ethanol and the production of a methane rich stream followed by the methane reforming of the methane rich stream to produce additional CO and CO2 and H2 that passes to the fermentation zone.
