Method for Accessing Microbial Diversity
A method of interfering with quorum sensing regulation of genes to promote cell growth is disclosed. The method of is aimed at accessing microbial biodiversity. The method involves obtaining an environmental sample comprising at least one novel (uncultivated in the laboratory) microorganism, contacting the environmental sample with an effective amount of an agent or combination of agents which interferes with the quorum sensing regulation of genes, growing the treated sample in a culture medium containing the quorum sensing signal disrupting agent or agents, and analyzing the colonies of microorganisms grown to demonstrate genetic novelty.

17 . A method of accessing microbial biodiversity, the method comprising:
a) obtaining a sample comprising at least one novel (uncultivated in the laboratory) microorganism,
b) contacting said sample with a physical device to which a microorganism can attach, and wherein said device acts to keep the concentration of a quorum sensing autoinducer below the threshold concentration required for the quorum sensing response,
(c) continuously washing said device with growth medium to maintain the concentration of the autoinducer at a low concentration, and
(d) analyzing colonies of microorganisms grown to demonstrate genetic novelty minimally at the species or subspecies level.
18 . The method of claim 17 , wherein said sample is an environmental sample.
19 . The method of claim 17 , wherein said sample is a human sample.
20 . The method of claim 17 , wherein said physical device is a membrane.
21 . The method of claim 17 , wherein said physical device is a hydroxyapatite disc.
