Antifouling composition and process for production thereof

摘要: This invention concerns a method for preparing bacterial supernatant comprising culturing cell of Pseudomonas environmental strain PF-11; and recovering the supernatant. also reducing amount biofilm on surface, adhesion at least one organism to or microfouling macrofouling surface contacting with supernatant, fraction, modified fraction composition PF-11, more acceptable carriers. killing growth fungus cell, inhibiting development an insect marine copepod, fungus, bacteria, copepod PF-11 culture; culture, substantially pure culture PF-11. that is enriched in provides identifying whether bacteria capable producing extracellular proteases digesting high molecular weight substrate.
