BACILLUS SUBTILIS SL2 WITH SURFACTANT PRODUCTIVITY FOR JUJUBE CULTIVATION AND A METHOD FOR PRODUCING A SURFACTANT USING THE SAME

摘要

PURPOSE: Bacillus subtilis SL2 is provided to be used as an agrochemical aid which enhances efficiency of an agrochemical ingredient and to produce an eco-friendly biosurfactant with biodegradation.;CONSTITUTION: Bacillus subtilis SL2(KCTC12007BP) has surfactant productivity. A method for preparing a culture medium with surfactant activity comprises a culturing the strain in a medium at 32 deg. C at 240 rpm for 24 hours. The medium is an LB medium containing 0.06%(w/v) of MnSO4, 1.0%(w/v) of trypton, 0.5%(w/v) of a yeast extract, and 0.5%(w/v) of NaCl.;COPYRIGHT KIPO 2013
