Microbial cell lines suitable for industrial-scale production of organic acids and methods of making and isolating such cell lines, and using the cell lines for production of organic acids.

This invention relates to a bio-leather coated fabric (1) which is obtained by decomposing the cellulose layer (2) produced by microorganisms after production and adding the necessary active ingredients to obtain a biopolymer filler (3) and by pressing and laminating the obtained biopolymer filler (3) to a surface such as paper, woven fabric, reflector fabric, polyester, silk fabric in the textile industry with natural adhesives, and production method thereof (100).

The present disclosure is directed to microorganisms that are genetically modified to express at least one exogenous enzyme involved in D-glucosamine uptake and metabolism. Methods for the production of an exopolysaccharide are also disclosed. The exopolysaccharide comprises N-acetylglucosamine and D-glucose and may be used as a bioresorbable implant for soft tissue repair, replacement, or augmentation.

The present invention provides a novel and potent cellulose producing bacterial species, Gluconacetobacter oboediens which was isolated from mixed fruit residue deposited at MTCC, IMTECH, Chandigarh under the deposition number MTCC 5610. The process for the production of microbial cellulose by this bacterium was optimized and thus, an efficient and economic process for producing high titers of microbial cellulose was developed. Further, a novel and improved method for drying of microbial cellulose has been developed wherein the microbial cellulose mats were dried using a wooden plank and porous fabric as a base at room temperature. The microbial cellulose production was successfully scaled up to 5 liters volume of production medium in trays. The present invention also recites the production and optimization of microbial cellulose in different shapes and sizes (gloves and vessels) which will be of great help for burn and injured persons/patients.

The invention relates to a micro-organism comprising a hydrogenase enzyme system which is capable of converting carbon dioxide into formic acid and a second enzyme system which is capable of converting formic acid into aliphatic carboxylic acids having a chain length of five or more carbon atoms. Also described are various methods for producing oil, as well as other aspects of the invention.

The properties of microbial pellicles are tuned by adjusting the physical culture conditions. A culture of Gluconacetobacter xylinus can be grown in a liquid growth media having a surface exposed to air so that a basal pellicle of microbial cellulose forms on the surface. Feeding the culture by adding additional liquid growth media at the surface, thereby submerging the basal pellicle; and then allowing the culture to grow again forms a second pellicle of microbial cellulose.

System and process are provided for producing and obtaining valuable products that are derived from microbial fermentation of C1-containing gaseous substrate process. More specifically, the disclosure provides schemes for the integration of a fermentation process with electrolysis process and C1-containing gaseous substrate generating process while achieving reduced carbon dioxide emission. The amount of carbon dioxide subject to the electrolysis process is based on the balance of raw material consumption of the microbial fermentation process.

A method of manufacturing a chitosan composition comprising steps performed in the following specific order: (i) preparing materials; (ii) creating a chitin ingredient from shrimp shells; (iii) creating a chitin ingredient from oyster mushroom; (iv) creating a chitin mixture by homogenously mixing the chitin ingredient from shrimp shells with the chitin ingredient from oyster mushroom; (v) loading the chitin mixture into the centrifugal spray drying device having predetermined specifications to create the chitosan composition; and (vi) packaging and preservation.

Integrated process for providing multiple raw materials to a downstream operation to generate an article of manufacture. Pyrolysis, torrefaction, reforming, partial oxidation, and/or gasification is integrated with gas fermentation. Integrated process converts carbon sources that would otherwise be vented to the atmosphere or discarded as waste to a fermentation product and one or more byproducts, which in turn are provided to a downstream operation to generate an article of manufacture. In certain aspects, the fermentation product may be ethanol, isoprene, butane diol, ethylene. In certain aspects, the byproduct may be metal, metal oxide, char, silica, and or steel. The downstream operation to generate an article of manufacture may be an operation to generate plastic products, rubber products, textiles, clothes, and the like.
