Abstract: A method is provided, whereby a crustacean virus is grown in fish cells. In particular, infectious hypodermal and hematopoietic necrosis virus (IHHNV) is grown in the established fish cell line, epithelioma papillosum cyprini (EPC).

Abstract: Biosynthetic production of 7-[1',2',6',-7',8',8a'(R)-hexahydro-2'(S),6'(R)-dimethyl-8'(S)-hydroxy-1'( S)-naphthyl]-3(R),5(R)-dihydroxyheptanoic acid, "triol acid", is accomplished by enzymatic hydrolysis of lovastatin acid or a salt thereof, by treating it with Clonostachys compactiuscula ATCC 38009 or ATCC 74178, or mutants thereof, or a cell-free extract derived therefrom, or a hydrolase derived therefrom. The triol acid and its lactone form are both inhibitors of HMG-CoA reductase and thus useful as anti-hypercholesterolemic agents, and may also serve as intermediates for preparation of other HMG-CoA reductase inhibitors. Also, in the synthesis of simvastatin by direct methylation of lovastatin, selective hydrolysis of residual lovastatin salt by treatment with Clonostachys compactiuscula ATCC 38009 or ATCC 74178 or mutants thereof or a cell-free extract derived therefrom, or a hydrolase derived therefrom yields the "triol" salt which can be easily separated from simvastatin.

Abstract: A process for modifying fats and oils which comprises applying partial glyceride lipase to fats and oils containing partial glycerides and fatty acids to synthesize triglycerides from the partial glycerides by esterification.The lipase is preferably an immobilized lipase and this process is preferably carried out under a water concentration of 1500 ppm or less.By using partial glyceride lipase according to the present invention, there can be obtained modified fats and oils having a low content of diglycerides without changing triglyceride composition.

Abstract: A novel antitumor substance BE-13793C or a pharmaceutically acceptable salt thereof, which is represented by the following formula: ##STR1## an anticancer agent comprising the novel substance or a pharmaceutically acceptable salt thereof, a method of producing the novel substance and a microorganism capable of producing the novel substance are disclosed.

Abstract: The present invention is concerned with a novel bioherbicide and its use to control Plantago major plantain. More specifically, the invention is concerned with Colletotrichum sp. G1 having the identifying characteristics of culture deposit No. ATCC 20980. The present invention is also concerned with a method for suppressing growth of plants of plantain in turfed and agricultural areas.

Abstract: Cross-linked polyglucans obtained by cross-linking polyglucans having branched chains intermolecularly and/or intramolecularly or cross-linked homooligomers obtained by cross-linking .alpha.-1,4-linked homooligomers of glucose intermolecularly can selectively adsorb glucoamylase and/or .beta.-amylase thereto. By the use of such three-dimensional, cross-linked high molecular weight substances, glucoamylase and .beta.-amylase can be isolated and purified extremely efficiently.

Abstract: A method is disclosed for enhancing the biocontrol effect of microbial biocontrol agents used to combat fungal plant disease. The microbial biocontrol agent is fermented, formulated, or packaged in the presence of deactivated target pathogen such as a culture lethally heated pathogenic fungus. The treated biocontrol agent is enhanced in its activity by the contact with the inactivated pathogen.

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: Riboflavin is removed from fermentation suspensions by them being heated at from 50.degree. to 90.degree. C. for from 1 to 3 hours, than cooled to from 0.degree. to 30.degree. C. over a period of from 1 to 5 hours, and subsequently being centrifuged to give a sediment fraction and liquid fraction in such a way that the sediment fraction contains predominantly riboflavin crystals as solid, and the liquid fraction contains virtually no crystalline riboflavin, and, where appropriate, resuspending the sediment fraction in from 0.5 to 2 parts by volume of water per part by volume of sediment fraction and repeating procedure c.

Abstract: Streptomyces parvullus, DSM 3816, produces on aerobic fermentation new antibiotics which are distinguished by antimicrobial activity even after derivatization.

Abstract: A composition which can bind heparin and promote cellular adhesion and neurite outgrowth is provided which consists essentially of a polypeptide of the formula:tyr-glu-lys-pro-gly-ser-pro-pro-arg-glu-val-val-pro-arg-pro-arg-pro-gly-vallys-asn-asn-gln-lys-ser-glu-pro-leu-ileu-gly-arg-lys-lys-thr-asp-glu-leu, or mixtures thereof.Medical devices such as prosthetic implants, percutaneous devices and cell culture substrates coated with the polypeptide composition are also provided.

Abstract: A process for producing an antibiotic compound which is normally one of several minor components in the cultivation of Z. arboricola ATCC 20868 to be the primary product is described.

Abstract: An assay with high sensitivity for activity of lecithin-cholesterol acyltransferase in blood for functional analysis of liver, by bringing the blood into contact with lecithin and free cholesterol until lysolecithin and cholesterol ester are produced, allowing the lysolecithin produced to react with lysophospholipase and glycerophosphocholine phosphodiesterase and assaying glycerol-3-phosphate produced simultaneously or successively in the reaction by means of an enzymatic cycling reaction in which glycerol-3-phosphate, dihydroxyacetone-3-phosphate, nicotinamide adenine dinucleotide (NAD), reduced NAD, O.sub.2, H.sub.2 O.sub.2, glycerophosphate oxidase and glycerophosphate dehydrogenase take part.
