Problems solved by technology

Among many marine organisms, sponges are currently one of the marine organisms with the most abundant active substances. People place great hopes on sponge active substances, but the content of active substances in sponges is very low, and the resources for fishing sponges are limited. The supply of drug sources Insufficiency makes sponge drug development significantly lag

Abstract

The invention discloses a culture medium for preparing Bacillamide C by fermenting and shrinking bacillus as well as preparation and application method thereof, belonging to the technical field of bacteria culture. The culture medium comprises the following components and contents: 3.64g / L of corn starch, 6.0g / L of tryptone, 6.29g / L of calcium carbonate, 4.0g / L of soya peptone, 0.10g / L of aminothiopropionic acid and 0.02g / L of tryptophan, wherein a solvent is artificial seawater. The invention cannot only meet requirement on shake flask experiment, but also can meet requirement on massively preparing Bacillamide C through fermentation of a fermentation tank.

Description

technical field [0001] The invention relates to a culture medium in the technical field of bacterial culture and its preparation, in particular to a culture medium for preparing Bacillamide C by fermenting Bacillus atrophaeus and its preparation and application method. Background technique [0002] Compared with terrestrial organisms, marine organisms live in an environment with harsh conditions such as high salt, high pressure, low temperature, and scarce nutrients. In order to survive, many marine organisms produce some chemical substances with unique structures in the long-term evolution process. A variety of active substances have been found from marine organisms, including anti-tumor compounds, tumor promoters, anti-inflammatory / allergic compounds, antibacterial, anti-viral compounds, biotoxins, anti-parasitic compounds, polyunsaturated fatty acids, etc., and a considerable part of them Active substances are not found in terrestrial organisms. These marine biologicall...
