Draft genome sequence of the biosurfactant-producing bacterium Gordonia amicalis strain CCMA-559, isolated from petroleum-impacted sediment. Repositório Alice
DOMINGOS, D. F.; DELLAGNEZZE, B. M.; GREENFIELD, P.; REYES, L. R.; MELO, I. S. de; MIDGLEY, D. J.; OLIVEIRA, V. C. de.
Gordonia amicalis strain CCMA-559 was isolated from an oil-contaminated mangrove swamp and shown to produce biosurfactants. This strain is a strict aerobe that readily degrades an array of carbon sources, including N-acetylglucosamine, cellobiose, Tween 80, and 4-hydroxybenzoic acid, and, like other G. amicalis strains, likely desulfurizes dibenzothiophene.

Production and characterization of surface-active compounds from Gordonia amicalis BABT
Jackisch-Matsuura,Ani Beatriz; Santos,Leonardo Silva; Eberlin,Marcos Nogueira; Faria,Andréia Fonseca de; Matsuura,Takeshi; Grossman,Matthew James; Durrant,Lucia Regina.
Two methods were used to make crude preparations of surface-active compounds (SACs) produced by Gordonia amicalis grown on the medium containing 1% diesel oil. Using a 2:1 (v/v) solution of chloroform:methanol for extraction, Type I SACs were isolated and shown to produce oil in water (O/W) emulsions. Type II SACs were isolated by precipitation with ammonium sulfate and produced predominantly water in oil emulsions (W/O). The crude Type I and II preparations were able to produce a significant reduction in the surface tension of water; however, the crude Type II preparation had 10-25 fold higher emulsification activity than the Type I preparation. Both SAC preparations were analyzed by the TLC and each produced two distinct bands with Rf 0.44 and 0.62 and...
