Application of Aspergillus in marine life

The application of Aspergillus in marine life is as follows. Marine Aspergillus has the ability to produce alkaloids by fermentation, and alkaloids have the ability to resist marine fouling. The antifouling detection method of alkaloids produced by marine Aspergillus in the patented technology of the invention takes the polluted microbial population as the detection object for the first time, and can comprehensively detect the antifouling potential of the compound. Some results can be recognized by naked eyes and have obvious antifouling effect. It has a good inhibitory effect on the growth of fouling bacteria that produce biofilm, such as psychrophilic Bacillus, Alternaria, Pseudomonas, Vibrio, Ruggiella, Rhodobacter and Sheva. It can be used as a microecological agent for marine antifouling, with good application potential and popularization prospect, and can provide scientific reference for the development of environmentally friendly marine biological agents.
