Description and Significance

Parvibaculum lavamentivorans DS-1T is a rod shaped, motile, gram-negative, non-pigmented, aerobic, chemoorganoheterotrophic bacterium. P. lavamentivorans readily form biofilms. Individuals are about 1.0 × 0.2 μm. The species is environmentally significant for its ability to catalyze the degradation of laundry detergents.

Genome Structure

The genome of Parvibaculum lavamentivorans is completely sequenced for representative strain DS-1T.[1] The DNA is packaged into one chromosome which contains 3.91Mb, 3715 genes and 3648 coding genes with 62.3%GC.

Cell Structure, Metabolism and Life Cycle

Parvibaculum lavamentivorans

Ecology

Parvibaculum lavamentivorans is capable of degrading 17 commercially important surfactants including linear alkylbenzenesulfonate (LAS). 2.5 million tons of LAS waste are produced each year. P. lavamentivorans degrades surfactants like LAS and releases short chain intermediates which are further degraded by local microbes.
