Unique lipids in Azotobacter vinelandii cysts: synthesis, distribution, and fate during germination.

abstract：:Microbial communities in the termite hindgut are essential for degrading plant material. We present the high-quality draft genome sequence of the Opitutaceae bacterium strain TAV1, the first member of the phylum Verrucomicrobia to be isolated from wood-feeding termites. The genomic analysis reveals genes coding for li...
