Abstract: A process for producing strains of Trichoderma virens which are deficient for production of viridiol for use as biocontrol agents is disclosed. These mutant strains are produced by treatment of viable T. virens with chemical or physical mutagens, preferably by irradiation with ultraviolet light. The treated fungi are then screened for production of viridiol to select for deficient strains. Following recovery, the mutant strains may be used as biocontrol agents for the control of plant diseases by application to the locus of a plant, seedling or seed to be protected. Coating seeds with the biocontrol agent prior to planting has been found to be particularly effective for the control of soilborne root or seedling diseases.

Abstract: An important intermediate for preparing cephalosporin antibiotics, 7-aminodesacetoxy cephalosporanic acid (7-ADCA), is prepared by a novel bioprocess in which a transformed Penicillium chrysogenum strain is cultured in the presence of an adipate feedstock to produce adipoyl-6-APA (6-amino penicillanic acid); and the in situ expression of an expandase gene, e.g., from Streptomyces clavuligerus, with which the P. chrysogenum has been transformed, converts the adipoly-6-APA by ring expansion to adipoyl-7-ADCA. The final product, 7-ADCA, is then prepared by cleavage of the adipoyl side chain using an adipoyl acylase. The entire synthesis, accordingly, is carried out using bioprocesses, and is efficient and economical.

Abstract: A drug resistant strain of P.chrysogenum has said drug resistance conferred by heterologous DNA, in particular a heterologous gene(s) under the control of a Penicillium control sequence(s). Drug resistance is especially to sulfonamides, or to trimethoprim or methotrexate by a gene derived from plasmid R388. A vector capable of conferring resistance to methotrexate or sulfonamide on P.chrysogenum, comprises at least one said resistance gene under the control of trpC controlling sequences.

Abstract: Disclosed is a method for transforming Penicillium chrysogenum. More particularly, the method includes obtaining an auxotrophic mutant of P. chrysogenum and employing an exogeneous segment of P. chrysogenum DNA capable of complementing said auxotorph so as to restore prototrophy. The exogeneous DNA segment thus comprises a phenotypic marker indicating successful transformation of the mutant.The exogeneous complementary DNA segment may further be prepared in a recombinant plasmid vector. These plasmid vectors include, by way of example, the pPctrpCL and pPctrpC.sub.6 plasmids developed by Applicants. These transforming plasmid vectors and those having identifying characteristics thereof are suitable for use in the subject transformation process. The exogeneous complementary DNA segment comprises a gene encoding a selected biosynthetic enzyme. By way of example, these genes include trpC, pyr4, argB and NO.sup.- reductase, as well as other genes which encode metabolically required enzymes.

Abstract: A process for producing a variety of chemical products, e.g., ethanol, by fermentation in which the product is removed from the fermentation medium as it is formed by liquid-liquid extraction using an extractant for the product which is immiscible with water.
