阅读：930发布：2021-02-18

专利汇可以提供Osmotic pressure control to improve thermophilic microorganism growth专利检索，专利查询，专利分析的服务。并且A method is described by which the osmotic pressure (of the medium in which thermophilic cellulolytic and ligninolytic microorganisms are grown on biodegradable organic waste material containing cellulose) is controlled in order to stimulate cell mass growth and cellulose digestion. Increase of osmotic pressure is controllably effected by providing a concentration of inorganic salt in the medium to the extent desired. Sodium chloride and soluble phosphate are exemplary salts.，下面是Osmotic pressure control to improve thermophilic microorganism growth专利的具体信息内容。

权利要求

1. IN THE METHOD FOR GROWTH OF CELLULOLYTIC AND LIGNINOLYTIC THERMOACTINOMYCES IN AN AQUEOUS LIQUID MEDIUM IN A FERMENTOR OR BIODEGRADBLE ORGANIC WASTE MATERIAL CONTAINING CELLULOSE AND/OR LIGNIN IN THE PRESENCE OF REQUISITE MINERAL SALTS AT A TEMPERATURE IN THE RANGE OF 45*C TO 80*C, A PH IN THE RANGE OF FROM ABOUT 7.0 TO ABOUT 8.5 AND AN OXYGEN CONCENTRATION OF 0.3 TO 2.0 MG. PER LITER, THE IMPROVEMENT COMPRISING ESTABLISHING AND MAINTAINING THE OSMOTIC PRESSURE OF SAID AQUEOUS LIQUID MEDIUM IN SAID FERMENTOR AT A VALUE IN THE RANGE BETWEEN THE OSMOTIC PRESSURE THAT WOULD BE INDUCED AT SAID TEMPERATURE IN PURE WATER BY THE DISSOLUTION THEREIN OF 0.5% BY WEIGHT OF SODIUM CHLORIDE AND THE OSMOTIC PRESSURE THAT WOULD BE INDUCED AT SAID TEMPERATURE IN PURE WATER BY THE DISSOLUTION THEREIN OF 3.3% BY WEIGHT OF SODIUM CHLORIDE.

2. The improvement of claim 1 wherein the osmotic pressure is established and maintained by the addition to the medium of a salt selected from the group consisting of sodium chloride and soluble phosphate salts.

3. The improvement of claim 2 wherein the salt is sodium chloride.

4. The improvement of claim 1 wherein a salt is generated in situ in the medium.

5. The improvement of claim 1 wherein the osmotic pressure is established and maintained by the addition to the medium of a combination non-toxic inorganic salts.

6. The improvement of claim 5 wherein sodium chloride and a soluble phosphate salt are used in combination.
