SP1d and its potential for environmental applicationsEmulsification activity (% EA24) values measured on cell-free media of Rhodococcus sp. SP1d grown on n-hexadecane, diesel, mineral oil, exhausted vegetagle oil and butter as the sole source of carbon and energy after 0, 48, 120, 168, and 240Â h of incubation.
