AI Technical Summary

Problems solved by technology

However, the amount of Streptomyces flavinus growing naturally in soil is too small to be insignificant
At present, there is no artificial production of such strains in China, and there is no corresponding production process and production equipment.
[0003] Compared with liquid fermentation, solid fermentation is more difficult to sterilize, the process is more difficult to control, it is easy to contaminate bacteria or mold, and the technology is very difficult, so it is difficult to succeed
Therefore, solid fermentation is rarely used in China, and there are almost no relatively mature solid fermentation processes.

Abstract

A solid fermenting process of xanthostreptomycete includes such steps as proportionally mixing soybean cake powder, peanut shell, corn flour, millet flour, wheat bran, and lime and water, high-pressure sterilizing at 128-135 deg.C for 60-90 min, inoculating seeds, and fermenting for 144 hr. Its apparatus is composed of dual-screw stirrer, disinfecting stainless steel tray, sterilizing carriage, high-pressure sterilizing pot, collectnig hopper, belt conveyer, humidify meter, fermenting tray and fermenting case.

Description

technical field [0001] The invention belongs to the technical field of Streptomyces luteus fermentation, and more specifically relates to the improvement of a solid fermentation process of Streptomyces luteus and production equipment thereof. Background technique [0002] Existing Streptomyces flavinus multiplies in the soil. During the growth process, it can dissociate a large amount of nitrogen, phosphorus, and potassium that have been solidified in the soil and cannot be absorbed by crops, improve the utilization rate of chemical fertilizers, and effectively alleviate the negative effects of soil compaction caused by extensive use of chemical fertilizers. At the same time, it can generate a variety of growth hormones to promote the growth of crops and improve their resistance to stress. Streptomyces flavinus can also produce a variety of antibiotics to inhibit the growth of pathogens, which is very beneficial to the elimination of soil-borne path...
