| Number | Title | Issue Date |
| 4377638 | Microbiological production of lower aliphatic carboxylic acids Lower aliphatic carboxylic acids of from 1 to 6 carbon atoms or salts thereof are prepared by culturing the microorganism Eubacterium limosum in a nutrient medium containing at least one member of the group consisting of carbon monoxide and a mixture of h... | 03/22/1983 |
| 4371619 | Acetic acid by fermentation Acetic acid has been prepared by a fermentation process using Clostridium thermoaceticum in a varied form obtained by repeated fermentations under anaerobic conditions and low redox potentials at successively more acidic pH's than the original organism.... | 02/01/1983 |
| 4364960 | Process for the production of vinegar with high acetic acid concentration A finished vinegar having an acetic acid concentration higher than 20 percent weight by volume is produced by repeating a fermentation cycle wherein a broth is fermented at 27°-32° C. in a 1st submerged fermentation tank by a continuous batch process, a... | 12/21/1982 |
| 4313960 | Preparation of concentrated natural vinegar A concentrated natural vinegar with an excellent natural flavor is prepared by treating a product obtained by freeze concentration of natural vinegar with a greater amount of alcohol obtained by natural fermentation than is already present in the natural ... | 02/02/1982 |
| 4282257 | Production of vinegar with high acetic acid concentration Vinegar having an acetic acid concentration higher than 18 percent weight by volume is produced in a submerged fermentation by maintaining the temperature of the fermenting broth after the initiation of the fermentation at 27°-32° C. until the acetic co... | 08/04/1981 |
| 4282323 | Removal and concentration of lower molecular weight organic acids from dilute solutions A process for obtaining lower carboxylic acids from aqueous lower carboxylic acid salts, such as obtained from a fermenter. The process involves converting the lower carboxylic acid salt to the corresponding acid with carbon dioxide, extracting the thus f... | 08/04/1981 |
| 4155813 | Fermentation process Fermentation process, e.g. for the production of an oxidation product such as vinegar, which comprises continuously cultivating a bacterial strain, preferably in a vessel of elongated shape, in a medium containing the substrate to be fermented in the pres... | 05/22/1979 |
| 4076844 | Two stage process for the production of vinegar with high acetic acid concentration A novel two-stage submerged fermentation process for producing vinegar with an acetic acid concentration of more than 15% is disclosed. In the first fermentation stage, the total concentration (i.e. the sum of the alcohol and acetic acid concentrations) i... | 02/28/1978 |
| 4022665 | Two phase anaerobic digestion An improved two phase anaerobic digestion process in which an initial phase continually receives an organic feed for short detention times of less than two days under conditions which efficiently liquefy and breakdown the feed to lower molecular weight ac... | 05/10/1977 |
| 3962035 | Hydrocarbon conversion process A process for the production of hydrocarbonaceous materials which comprises reacting waste materials with a microorganism to produce organic products and treating the resultant organic products with a catalyst comprising a decarboxylation catalyst is disc... | 06/08/1976 |
