Patent number: 5470729Abstract: Methods of isolating deletion mutants of Vibrio cholerae. In one method, the deletion is predetermined by digestion with restriction endonucleases of known specificity. The deletions are inserted into the Vibrio cholerae chromosome by in vivo recombination between a plasmid carrying the desired deletion, with adjacent flanking sequences, and the Vibrio cholerae chromosome. In another method, an initial in vivo recombination event of homologous sequences from the recombinant plasmid into the chromosome provides a selectable marker at this site. A second in vivo recombination event between homologous flanking sequences results in excision of proficient genes from the chromosome with the end product being a deletion mutation. Also provided are methods for the isolation and characterization of a new Vibrio cholerae strain having a deletion in the ctx gene, as defined by Acc I, Xba I, Cla I and/or restriction endonuclease sites and further having a deletion in the gene encoding zonula occludens toxin (zot).Type: GrantFiled: August 12, 1992Date of Patent: November 28, 1995Assignee: University of Maryland At BaltimoreInventors: James B.

Patent number: 4753181Abstract: A coincineration process whereby sewage sludge or other toxic liquid chemical waste is incinerated with a supplemental fuel such as municipal refuse, coal, sawdust, tire chips and the like involves introducing the sewage sludge into the incineration zone by means of a pressure spray nozzle or a spinning cone or disc atomizer. In the form of ultrafine solids, liquid or gas, a supplemental fuel may be introduced with the sewage sludge. Supplemental fuel may also be introduced into the incinerator by conventional means. Addition of tire chips in the feed provides in a higher incineration zone temperature and significantly reduces dioxin compounds present in the incineration zone off gas. Also, to reduce the scaling and fouling of the boiler tubes and incinerator, to increase the density and pumpability of the sewage sludge, and to eliminate metal salt deposits from the incinerator, the boiler feedwater and the sewage sludge are each contacted with an electromagnetic field device prior to heating.Type: GrantFiled: June 9, 1987Date of Patent: June 28, 1988Inventor: Leon Sosnowski
