Abstract: This invention relates to a method of selectively degrading .beta.-lactoglobulin contained in cow's milk-serum protein by using a specific enzyme capable of selectively degrading .beta.-lactoglobulin.

Abstract: The invention describes a colonic crypt cell stimulating mitogen, and conditioned medium containing it. In particular, cell line LIM 2537 is described which, when cultivated in medium, secretes a mitogen which stimulates the proliferation o colonic crypt cells. Applications of the conditioned medium and the cell line are also described.

Abstract: The present invention relates to a multicellular, three-dimensional, living mammalian tissue. The tissue is produced by a co-culture process wherein two distinct types of mammalian cells are co-cultured in a rotating bioreactor which is completely filled with culture media and cell attachment substrates. As the size of the tissue assemblies formed on the attachment substrates changes, the rotation of the bioreactor is adjusted accordingly.

Abstract: An insect cell line has been established and characterized, derived from embryonic tissue (BTI-TN-5B1-4, ATCC CRL 10859) of Trichoplusia ni (cabbage looper). The line is susceptible to various baculoviruses, including TnSNPV and AcMNPV, and may be used to replicate such viruses for use as insecticides or otherwise.

Abstract: Two new insect cell lines have been established and characterized; the cell lines were derived from midgut (BTI-TN-MG1, ATC CRL 10860), and embryonic tissue (BTI-TN-5B1-4, ATC CRL 10859) of Trichoplusia ni (cabbage looper). The lines are susceptible to various baculoviruses, including TnSNPV and AcMNPV, and may be used to replicate such viruses for use as insecticides or otherwise.

Abstract: A cell treatment composition based on a non-selective complete nutrient medium and also including a yeast derivative, one or more antioxidants, an oxygen tension reducing agent and one or more fatty acids between 10 and 25 carbon atoms in length having from 0 up to 4 double bonds. Nutrient medium additives for treatment of injured, damaged or stressed cells containing a yeast derivative, one or more antioxidants, an oxygen tension reducing agent and one or more fatty acids between 10 and 25 carbon atoms in length having from 0 up to 4 double bonds. Methods for treating prokaryotic and eukaryotic cells, including the steps of providing one or more injured, damaged or stressed cells and supplying the cells with an environment that includes a non-selective complete nutrient medium and also contains a yeast derivative, one or more intracellular antioxidants, oxygen tension reducing agent and one or more fatty acids between 10 and 25 carbon atoms in length having from 0 to 4 double bonds.

Abstract: A process for preparing fatty acid microspheres of microorganisms by rotary disc processing is disclosed. The process is designed to minimize heat risk to the microorganisms during production. Microsphere particles of fatty acid matrix containing microorganisms, preferably stearic acid encapsulated Enterococcus faecium, are also provided.

Abstract: This invention relates in part to the use of osmoticants to provide desiccation tolerance to growth producing cells of microorganisms upon drying and reconstitution.This invention also relates in part to the discovery of liquid fermentation media permitting production of high levels of conidia of Trichoderma harzianum in liquid fermentation, and modifications to these media that produce conidia that are resistant to desiccation and that provide enhanced biocontrol efficacy.

Abstract: This invention relates to mutants or variants of Bacillus thuringiensis producing high amounts of active delta-endotoxins. The delta-endotoxins produced by the mutant or variant B. thuringiensis will have an activity directed towards the same pest insects as its parent B. thuringiensis delta-endotoxins, such as against lepidopterans (mutants from B. thuringiensis subsp. kurstaki or subsp. aizawai), dipterans (mutants from B. thuringiensis subsp. israelensis) or coleopterans (mutants from B. thuringiensis subsp. tenebrionis).
