Patent number: 5118725Abstract: A biologically degradable film is prepared consisting of a synthetic polymer and a biologically degradable polymer. The biologically degradable polymer is divided into small particles by means of enzymes produced by microbes in the form of spores, which enzymes split and release small molecules from the surface of the biopolymer particles.

Patent number: 4837155Abstract: A method of producing Trichoderma conidia in submerged culture comprises first preparing an inoculant of a desired strain of Trichoderma. Then, the inoculum is placed in a sufficient volume of a suitable liquid medium. The medium is maintained under substantially constant illumination, agitation and aeration at a temperature from about 25.degree. C. to about 30.degree. C., and a pH from about 5.8 to about 7.0. The culture is grown from a sufficient period of time until the density of conidia is about 5.0.times.10.sup.8 per ml, and then the conidia so produced are harvested. A similar method is provided for the production of Trichoderma chlamydospores.Type: GrantFiled: May 22, 1987Date of Patent: June 6, 1989Assignee: Bio-Technology General Corp.Inventor: Mordechai Tabachnik

Patent number: 4797361Abstract: This invention includes a process for producing and using increased quantities of extracellular glycoprotein (particularly cellulolytic) enzymes by permitting the enzyme-producing microbial strain to undergo a preliminary growth phase, preferably at about 37.degree. C., and then an enzyme-secretion phase. Also included is a specific microbial strain, RL-P37 of Trichoderma reesei, which grows well at 37.degree. C. and the cellulasic products thereof.Type: GrantFiled: September 11, 1987Date of Patent: January 10, 1989Assignee: Lehigh UniversityInventor: Bland S. Montenecourt

Patent number: 4762788Abstract: This invention concerns a process of producing cellulolytic enzymes by fermentation with the Trichoderma reesei fungus.This process includes two steps:(a) a first step of subjecting to aerobian fermentation a culture medium comprising a strain of Trichoderma reesei, nutrition compounds and a small quantity of cellulose and sugar,(b) a second step of contining the aerobian fermentation by adding soluble sugar at a speed such that the sugar concentration in the fermentation zone remains under 0.3% by weight.The cellulolytic enzymes obtained are used in the enzymatic hydrolysis of a lignocellulosic biomass.Type: GrantFiled: November 28, 1984Date of Patent: August 9, 1988Assignee: Institut Francais du PetroleInventors: Michel Warzywoda, Veronique Ferre, Jacques Pourquie

Patent number: 4725544Abstract: The separation of xylanases from mixtures thereof with other hemicellulases, particulary cellulase produced by the culturing of hemicellulolytic microorganisms, particularly the fungus Trichoderma harzianum E58 and Trichoderma reesei by ultrafiltration through an ultrafiltration membrane having a low molecular weight cut-off point in the range of about 1,000 to 20,000 daltons to obtain a cellulase rich retentate and xylanase rich ultrafiltrate. The dilute xylanase rich filtrate from the ultrafiltration is concentrated and purified by adsorption and elution from an insoluble matrix, e.g. a cationic exchange resin. The xylanase obtained is suitable for use in the hydrolysis of hemicellulose for which it is selective, particularly in the presence of cellulose and the cellulase rich retentate is suitable for the hydrolysis of cellulose.Type: GrantFiled: April 25, 1986Date of Patent: February 16, 1988Inventors: Larry U. Tan, John N. Saddler, Ernest K. Yu

Patent number: 4642131Abstract: Compost is rendered suppressive to plant pathogens, such as Rhizoctonia solani, Pythium ultimum and Fusarium, and/or diseases caused thereby by adding to the compost, desirably after peak heating has been achieved but before substantial recolonization of the compost by mesophilic microorganisms has occurred, one or more microorganisms antagonistic to the plant pathogen. Desirably the inoculated antagonistic microoganisms comprise Trichoderma hamatum species A.T.C.C. No. 20765 or 20764, together with a Pseudomonas maltophilia bacterium species A.T.C.C. No. 53199 or a Flavobacterium species, A.T.C.C. No. 53198.Type: GrantFiled: July 22, 1985Date of Patent: February 10, 1987Assignee: The Ohio State UniversityInventor: Harry A. J. Hoitink

Patent number: 4634670Abstract: Cellulase may be prepared in good yield and at relatively low cost by culturing certain mutant strains of the genus Trichoderma, which exhibit increased inducibility of cellulase by L-sorbose, in medium wherein the carbon source comprises cellulose-containing material of plant origin, for example, bagasses, waste papers, rice plant hulls and straws or soybean wastes. Preferred mutant strains are exemplified by Trichoderma reesei PC-1-4, PC-3-7, X-30 and X-31.Type: GrantFiled: July 27, 1984Date of Patent: January 6, 1987Assignee: Shin Nenryoyu Kaihatsu Gijutsu Kenkyu KumiaiInventors: Seigo Takasawa, Yasushi Morikawa

Patent number: 4600589Abstract: Meat is tenderized by adding thereto a proteolytic enzyme obtained by culing the microorganism, Trichoderma reesei strain MCG 80. The enzyme is an aspartic acid protease with proteolytic properties similar to the animal protease, Cathepsin D. The enzyme acts selectively upon the myofibrillar proteins of meat producing a desirable uniform texture. Culturing of the microorganism in a medium containing glucose and lactose results in high enzyme yield.Type: GrantFiled: October 22, 1984Date of Patent: July 15, 1986Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Frederick M. Robbins, Alfred L. Allen, John E. Walker, Samuel H. Cohen
