Abstract: Disclosed is a process for preparing biodiesel from renewable oil and fat catalyzed by lipase with online dehydration. The method uses a short chain alcohol ROH as an acyl-acceptor, and utilizes a lipase as the catalyst to catalyze transesterification reaction of oil and fat feedstock with said short chain alcohol, so as to synthesize biodiesel; and online dehydration with a membrane or a molecular sieve is carried out during the whole process or part of the reaction process. Such online dehydration process greatly simplifies the operation procedure, and provides good economic and environmental benefits.

Abstract: Disclosed herein are techniques for computationally designing enzymes. These techniques can be used to design variations of naturally occurring enzymes, as well as new enzymes having no natural counterparts. The techniques are based on first identifying functional reactive sites required to promote the desired reaction. Then, hashing algorithms are used to identify potential protein backbone structures (i.e., scaffolds) capable of supporting the required functional sites. These techniques were used to design 32 different protein sequences that exhibited aldol reaction catalytic function, 31 of which are defined in the Sequence Listing. Details of these 31 different synthetic aldolases are provided, including descriptions of how such synthetic aldolases can be differentiated from naturally occurring aldolases.

Abstract: In a method for controlling the growth of microbes grown in a medium to high cell-densities by the fed-batch technology, a two-phase system, having a liquid phase (cultivation medium) and a solid or gel phase, the solid or gel phase provides a source of substrate-delivering polymer which is turned by an enzyme in a controlled way into a growth-limiting substrate or pH adjusting agent. Also described is a method for restricting the synthesis of growth-limiting metabolites and preventing oxygen-depletion in microbial cell cultures.

Abstract: The invention relates to improvements in the production of ethanol and acetate by microbial fermentation, particularly to production of alcohols by microbial fermentation of a substrate comprising CO and the addition of an inorganic sulfur additive.

Abstract: A wastewater treatment process elicits microorganisms to convert a waste stream/organic resource to intracellular biopolymer polyhydroxyalkanoate (PHA). The process includes (i) waste stream/organic resource composition feed criteria, (ii) configuration coupled with operational parameters, and (iii) PHA-laden biomass separation and stabilization. A waste stream/organic resource capable of producing enhanced levels of PHA may be selected based on a combination of criteria, which may include short chain fatty acid concentration, protein concentration, polysaccharides concentration, and total suspended solids concentration. The waste stream is introduced into an aeration basin upon a specific configuration and operated under various parameter combinations for selecting/enriching microorganisms capable of producing PHA. The PHA-laden biomass is separated and stabilized for downstream PHA related product beneficial uses.
