Abstract: Disclosed are methods using neutral red to mediate the interconversion of chemical and electrical energy. Electrically reduced neutral red has been found to promote cell growth and formation of reduced products by reversibly increasing the ratio of the reduced:oxidized forms of NAD(H) or NADP(H). Electrically reduced neutral red is able to serve as the sole source of reducing power for microbial cell growth. Neutral red is also able to promote conversion of chemical energy to electrical energy by facilitating the transfer of electrons from microbial reducing power to a fuel cell cathode.

Abstract: Disclosed herein are methods for regulation of fat and/or cholesterol uptake from the gastrointestinal tract and/or regulation of plasma fat and/or cholesterol levels comprising administering to a mammal in need thereof an effective amount of a regulator of pancreatic IB PLA2 functionality. Also disclosed herein are methods of regulating the function of a polypeptide of interest comprising inserting of the 62-66 loop region of a pancreatic IB PLA2 amino acid sequence into the polypeptide of interest; and administering an effective amount of a regulatory molecule that effects its regulation through said amino acid sequence. Further disclosed are novel bile salt compounds that regulate pancreatic IB PLA2. Methods for detecting altered pancreatic IB PLA2 function and methods for identifying an agent suitable for regulating pancreatic IB PLA2 enzyme functionality are also disclosed.

Abstract: A fermentation process for making succinic acid in high concentrations employs a bacteria obtained from the rumen contents of cattle. A preferred bacteria is Bacterium 130Z (ATCC No. 55618).

Abstract: The present invention relates to a biological method for dechlorinating polychlorinated biphenyls (PCBs) by inoculating a polychlorinated biphenyl containing sample with PCB dechlorinating anaerobic methanogenic granules. The granules are made by coculturing particles of a PCP-dechlorinating methanogenic microbial consortia and a PCB-dechlorinating microorganism under anaerobic conditions in an upflow anaerobic sludge blanket (USAB) reactor.

Abstract: A method for producing succinic acid in high concentration by fermentation employs a variant of strain 130Z which is resistant to concentrations of about 1 g/l to about 8 g/l of sodium monofluoroacetate. The variant produces succinic acid in concentrations of about 80 g/l to about 110 g/l and the fermentation product contains less formic and acetic acids than the product obtained using the parent strain under identical conditions. The novel variants and a method of obtaining such variants also are described.

Abstract: A method for making succinic acid employs a fluoroacetate resistant variant of Anaerobiospirillum succiniciproducens. The fluoroacetate variant produces a succinic acid product which contains less acetic acid than the product obtained using the parent strain under identical conditions. A preferred variant FA-10 is obtained from A. succiniciproducens (ATCC No. 29305). A method of obtaining the variant also is described.

Abstract: A method for reducing the size of coal particles includes the steps of inoculating a coal sample with an anaerobic bacteria or decarboxylating enzyme therefrom and incubating the inoculated sample. The microbes and/or decarboxylating enzymes biochemically modify the coal to reduce the size of the coal to ultra-fine particles. The biotreatment modifies the coal so as to improve its dispersibility in coal-water slurries.

Abstract: A biologically pure asporogenic mutant of Clostridium acetobutylicum is produced by growing sporogenic C. acetobutylicum ATCC 4259 and treating the parent strain with ethane methane sulfonate. The mutant which as been designated C. acetobutylicum ATCC 55025 is useful in an improved ABE fermentation process, and produces high concentrations of butanol and total solvents.

Abstract: A process for economically producing highly purified succinic acid comprises growing a succinate-producing microorganism on a low cost carbohydrate substrate; simultaneously neutralizing the fermentation broth and precipitating the succinate as calcium succinate by adding a calcium ion source to form calcium succinate; isolating the calcium succinate; slurrying the calcium succinate in water and treating it with sulfuric acid to form calcium sulfate and succinic acid; and then treating the succinic acid with first a strongly acidic ion exchanger and then a weakly basic ion exchanger to remove impurities and obtain a highly purified succinic acid product. In a preferred embodiment, the calcium succinate is isolated from the fermentation broth by filtration; the filtrate is heated to precipitate additional calcium succinate; and, the spent filtrate which contains nutrients is recycled to the fermentor.

Abstract: A process including multistage continuous fermentation followed by batch fermentation with carefully chosen temperatures for each fermentation step, combined with an asporogenic strain of C. acetobutylicum and a high carbohydrate substrate concentration yields extraordinarily high butanol and total solvents concentrations.

Abstract: This invention relates to compounds of the structures: ##STR1## which structure includes its isomers, conventionally designated (E,Z)-4,5,9-trithiadodeca-1,6,11-triene 9-oxide and commonly termed (E,Z)-ajoene. This invention also relates to a process for preparing the compounds which comprises extracting and isolating allyl disulfide oxide (allyl 2-propenethiosulfinate) from the bulbs of garlic plants and thereafter treating it with a lower alkyl alcohol to produce such compound and the compounds as antibiotic and particularly as antithrombotic agents.
