Straw biological feed technology principle

Crop stalks have high crude fiber content and are difficult to be digested and absorbed by animals. They can use less nutrients and have poor palatability. They are classified as roughage in feed taxonomy. Cellulose is an aggregate of D-glucopyranose, and hemicellulose is a heteropolysaccharide polymerized from various monosaccharide residues such as glucose, xylose, mannose, arabinose, and galactose. In addition, in the plant, There is also a non-polysaccharide material, lignin, formed by the polymerization of phenylpropane. Cellulose, hemicellulose and lignin are tightly bound and intertwined to form crude fibers, which are the main components of plant cell walls. These natural organic macromolecule compounds have a very strong structure and can only swell and swell. They cannot be decomposed by digestive fluids and enzymes for monogastric animals, but rely on a small amount of glycolysis by the cecum microbes, and the digestibility is low. Only suitable for the breeding of ruminants. At the beginning of this century, according to the principles of bionics, people studied the digestive mechanisms and gastrointestinal microflora of ruminants such as cattle, horses and sheep. Inspired by the ruminal mechanism of cattle, people conducted research on the biological characteristics of rumen microorganisms, separation, identification and pure culture techniques, as well as the discussion of rumen micro-ecological artificial simulation technology, and made gratifying progress. In the 1990s, modern bio-engineering technologies are changing with each passing day, and various new and high-tech methods emerge one after another. During the Eighth Five-Year Plan period, with support from the State Science and Technology Commission and with the assistance of the FAO, the research results of the latest bioengineering technologies in agricultural developed countries such as the United States and Australia were introduced, and the screening and artificial mutation of fiber-decomposing bacteria strains were mainly carried out. The work on crossbreeding and breeding, etc., has cultivated an engineering strain that can rapidly breed and efficiently secrete a cellulolytic enzyme system under natural conditions, completed the pure culture, deep dormancy, and formulation research of the strain, and the straw biological treatment technology adopts this. A special kind of project, under the combined effects of mold, basidiomycetes, bacteria and related chemical substances, carries out a series of complex biochemical actions to change the physical and chemical properties of the straw. The crude fiber contained therein is degraded into small molecules such as monosaccharides, disaccharides, and amino acids that are easily digested and absorbed by animals, thereby increasing the digestion and absorption rate of the feed and playing a role in the deep biochemical processing of the feed machinery. At the same time, a large amount of nutrient-rich microbial cell proteins and other useful metabolites, such as organic acids, alcohols, aldehydes, esters, vitamins, antibiotics, trace elements, etc., are also produced and accumulated in the process of straw biological treatment, so that the feed becomes softer. Fragrance, increased nutrition. And contains a variety of digestive enzymes, a variety of unknown growth factors, can enhance animal disease resistance, stimulate their growth and development, some metabolites also have antiseptic effect on feed (such as lactic acid, acetic acid, ethanol, etc.), can extend the shelf life of the feed . The project passed the national inspection and acceptance. The technical indicators of the project are: crude fiber 15.21%, crude protein more than 15%, opening up vast space for monogastric animals to use stalks, and further exploring the use of cellulase and high-yield SCP strains during the Ninth Five-Year Plan period. The mixed bacteria fermented straw processing method enables the corn straw protein content to reach 19.63% - 24.14%, and the crude fiber utilization rate exceeds 70%, thus expanding the use of straw to pigs, chickens, fish, cattle, horses, sheep, etc. Almost all livestock and poultry.

PGA is a water soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation. PGA is a sticky material first found in "natto", a fermented soybean. PGA is an unusual anionic, naturally occurring homo polyamide that is made of D & L glutamic acid units connected by amide linkages between alpha amino & gamma carboxylic acid groups.
Gamma-poly-glutamic acid (gamma-PGA) is a natural occurring, multi-functional, and biodegradable biopolymer.

It is produced through fermentation by Bacillus subtilis using glutamic acid. PGA is consists of glutamic acid monomers crosslinked between α-amino and γ-carboxyl groups, and the molecular weight of PGA is usually between 100~1000 kDa. It is water-soluble, edible and non-toxictowards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment.
