Modified Heteropolysaccharides And Their Preparation

View page
US Patent:
41828607, Jan 8, 1980
Filed:
May 9, 1977
Appl. No.:
5/794725
Inventors:
Lars A. Naslund - Morganville NJ
Allen I. Laskin - New York NY
International Classification:
C12D 1304
C08B 3700
E21B 4322
US Classification:
536114
Abstract:
A process for producing modified heteropolysaccharides derived from a bacteria of the genus Xanthomonas, comprising the steps: (a) preparing an aqueous solution which contains (i) from about 200 to about 30,000 parts per million, by weight of an impure and unmodified heteropolysaccharide product and (ii) at least about 0. 5 weight percent of at least one salt to obtain a saline heteropolysaccharide solution; (b) heating said saline heteropolysaccharide solution to a temperature of at least about 100. degree. C. ; (c) maintaining said saline heteropolysaccharide solution at a temperature of at least about 100. degree. C. for a period of time sufficient to increase the injectivity and filterability characteristics of the heteropolysaccharide but for an insufficient time to impair the viscosity imparting properties of the heteropolysaccharide; and (d) removing or separating the proteinaceous materials and/or residual whole bacterial cells or other cell debris from the saline and heat-treated heteropolysaccharide product. The solution is preferably filtered or otherwise treated to separate the modified heteropolysaccharide from bacterial cells, cellular debris and other materials, prior to being put to use in, e. g. , oil recovery processes, additive for foodstuffs, pharmaceutical preparations, etc.

Immobilized Glycoenzymes

View page
US Patent:
39705218, Jul 20, 1976
Filed:
Aug 7, 1974
Appl. No.:
5/495339
Inventors:
Oskar R. Zaborsky - Watchung NJ
Allen I. Laskin - New York NY
Assignee:
Exxon Research and Engineering Company - Linden NJ
International Classification:
C07G 702
US Classification:
195 63
Abstract:
Glycoenzymes are immobilized by oxidizing a carbohydrate portion of the enzyme to a carbonyl group or a precursor thereof and reacting the resultant carbonyl group on the enzyme with an amino group of an amino-containing water insoluble polymer to produce a water insoluble conjugate. This method avoids loss of enzyme activity as a result of the carbohydrate portion of the enzyme which is catalytically inert being utilized in preparing the water-insoluble conjugate.

Method For Producing Microbial Cells And Use Thereof To Produce Oxidation Products

View page
US Patent:
43755151, Mar 1, 1983
Filed:
Dec 11, 1980
Appl. No.:
6/215248
Inventors:
Ramesh N. Patel - Edison NJ
Allen I. Laskin - New York NY
Assignee:
Exxon Research and Engineering Co. - Florham Park NJ
International Classification:
C12N 902
US Classification:
435189
Abstract:
Disclosed are newly discovered and isolated methylotrophic microorganism strains and their natural and/or artificial mutants which grow well under aerobic conditions in a culture medium in the presence of methane as the major carbon and energy source. The methane-grown microbial cells possess a high content of protein and can be utilized as such as feedstuffs. The methane-grown microbial cells or enzyme preparations thereof are also useful in converting C. sub. 1 -C. sub. 6 alkanes to alcohols, particularly methane to methanol, C. sub. 3 -C. sub. 6 alkanes to the corresponding C. sub. 3 -C. sub. 6 sec. alcohols and methyl ketones, C. sub. 3 -C. sub. 6 sec. alcohols to the corresponding methyl ketones, cyclic hydrocarbons to cyclic hydrocarbyl alcohols (e. g. , cyclohexane to cyclohexanol) C. sub. 2 -C. sub. 4 alkenes selected from the group consisting of ethylene, propylene, butene-1 and butadiene to 1,2-epoxides, styrene to styrene oxide, and converting other oxidizable substrates to oxidized products.
