Marine bacteria from the Gulf of California with antimicrofouling activity against colonizing bacteria and microalgae

One way of reducing the input of pollutants into the marine environment is to enforce the use of non-toxic antifouling paints in marine protected areas. Thus, the purpose of this study was to detect marine microorganisms that secrete inhibitory substances against bacteria and microalgae to avoid bio...
