Ten LAS-resistant strains were isolated, and all were found to be Gram-negative bacteria such as Enterobacter and Pseudomonas. Thereafter, we tested the ability of each bacterial isolate to resist the antibacterial activity of the surfactant. The samples were treated with 2.0% LAS or POLE at 25☌ for 30 min and cultivated on agar plates at 25☌ for several days, after which manifold bacterial colonies were isolated. In the present study, we isolated surfactant-resistant bacteria from soil samples collected from a sports ground and a farm field. N2 - Linear alkylbenzene sulfonate (LAS) and polyoxyethylene lauryl ether (POLE) are the major surfactants in washing detergents. This study was supported by a grant from the All Japan Laundry and Drycleaning Association. T1 - Isolation and identification of soil bacteria resistant to surfactants in washing detergents Therefore, the combination of LAS and POLE could be more effective to eliminate soil bacteria from clothes and/or daily necessities.", The genera of LAS- and POLE-resistant bacteria did not overlap. Notably, one POLE-resistant strain was identified as Bacillus cereus, a potential causative agent for foodborne illness. On the other hand, 18 POLE-resistant strains were isolated, of which 14 were Gram-positive bacteria including Bacillus and Microbacterium. Therefore, the combination of LAS and POLE could be more effective to eliminate soil bacteria from clothes and/or daily necessities.Ībstract = "Linear alkylbenzene sulfonate (LAS) and polyoxyethylene lauryl ether (POLE) are the major surfactants in washing detergents.
