Bioactive properties of microbial communities associated with seaweeds

Microbial communities associated with seaweed have huge potential of synthesizing several bioactive compounds due to its diverse nature and the interactions with the surrounding environment. Thorough knowledge on the culture and storage characteristics of the bacterial strain is required for the pilot scale production of the bioactive compounds. The microbial isolates associated with seaweeds were reported to have growth promotic effect, in all the stages of seaweed life cycle starting from spore release and germination, to biomass production and which intern influence the bioactive properties of the seaweed. The complex reactions like beneficial and pathogenic interaction with bacteria are required for the stimulatory as well as inhibitory effect on cell division and tissue generation in seaweeds. The microbial communities on seaweed surfaces also gives the protection to the surrounding living organisms and its environments in the form of sperm germination and larval settlement, producing quorum sensing signals to attract or inhibit the entry of harmful organism.
