Abstract: Bacillus thuringiensis cultures deposited as NRRL B-18747, NRRL B-18749 and NRRL B-18750 have dipteran activity. Thus, these cultures, or mutants thereof, can be used to control such insect pests. Further, genes encoding novel .delta.-endotoxins can be removed from these cultures and transferred to other host microbes, or plants. Expression of the .delta.-endotoxins in such hosts results in the control of susceptible insect pests in the environment of such hosts.

Abstract: Disclosed and claimed is a novel Bacillus thuringiensis isolate designated B.t. NRRL B-18721 which has activity against dipteran insect pests. Thus, this isolate, or mutants thereof, can be used to control such insect pests. Further, genes encoding novel .delta.-endotoxins can be removed from the isolate and transferred to other host microbes, or plants. Expression of the .delta.-endotoxins in such hosts results in the control of susceptible insect pests in the environment of such hosts.
Abstract: The subject invention pertains to novel microorganisms useful for the control of unwanted grasses and other weeds. The microorganisms of the subject invention are discovered through a unique process which involves isolating plant pathogens from asymptomatic plants.
Abstract: Butyrylcholinesterase is produced in a purity of at least 90% by subjecting plasma fraction IV-4 alone or in admixture with fraction IV-1 to both anion exchange chromatography and affinity chromatography.
Abstract: A glyceride produce free from triglycerides and containing mostly monoglycerides is made by mixing glycerol and fatty acids with a lipase which is isolated from Penicillium cyclopium ATCC 34613.
Abstract: A substantially pure preparation of thermostable RNase H is disclosed. In one preferable form of the invention, the RNase H is capable of biological activity after incubation at temperatures equal to or greater than 70.degree. C. for at least ten minutes. In another preferable form of the invention, the purification is from Thermus thermophilus or a closely related organism. The present invention is also a method of digesting RNA polymers that are in duplex form with a DNA molecule. The method comprises exposing the duplex to the isolated thermostable RNase H.
Abstract: Disclosed is a method for reducing the allergenicity of psyllium seed husk by treatment with an enzyme. An aqueous slurry of psyllium seed husk is treated with the enzyme under conditions sufficient to inactivate the allergenic protein thus reducing the allergenicity of the psyllium seed husk.
Abstract: Disclosed and claimed is a novel Bacillus thuringiensis isolate designated B.t. PS192N1 which has dipteran activity.

Abstract: A proteinase-resistant cellulase, a microorganism producing the same, and a process for producing such a proteinase-resistant cellulase is disclosed. The cellulase can be used as an additive to detergent compositions for washing clothes containing a proteinase, without immobilization or stabilization by chemical modification. The proteinase-resistant cellulase can be produced by a novel microorganism, Aspergillus niger KSM-24 [deposited with Fermentation Research Institute, Agency of Industrial Science and Technology (FERM BP-3359)].
Abstract: A novel megakaryocyte colony stimulating factor has been isolated from the supernatant of the culture obtained by cultivating a cell strain of a human large cell lung cancer. When the factor is applied to human or murine bone-marrow cells in vitro, it forms a megakaryocyte colony. Also, the factor increases the number of platelets in peripheral blood in vivo.
Abstract: A process for the manufacture of alkaline earth salts of acetic acid. Biomass is fermented under appropriate conditions to produce acetic acid, which is extracted from the fermentation broth with the aid of a basic liquid ion exchanger dissolved in an organic phase. The organic phase containing the product acetic acid is then reacted directly with a basic material such as limestone, and the resulting alkaline earth acetate product is recovered from the aqueous phase.
Abstract: A novel D-amidase is described. The enzyme specifically hydrolyzes D-.alpha.-alanineamide into D-.alpha.-alanine. It is produced by culturing a microorganism belonging to the genus Arthrobacter, and is useful as an enzyme for efficiently producing D-.alpha.-alanine having a high optical purity and/or L-.alpha.-alanineamide from DL-.alpha.-alanineamide or D-.alpha.-alanineamide at low cost.
Abstract: The present invention relates to microorgaisms which produce the aroma and flavor of traditional Korean soybean paste.
