Nematode of industrial importance is

Nematode of industrial importance is Turbatrix aceti.
Turbatrix aceti (vinegar eels, vinegar nematode, Anguillula aceti) are free-living nematodes that feed on a microbial culture called mother of vinegar (used to create vinegar) and may be found in unfiltered vinegar. They were discovered by Pierre Borel in 1656.
Manufacturers normally filter and pasteurize their product before bottling, destroying the live bacterial and yeast culture that these nematodes require for sustenance.
