Assessment of antibiofilm and quorum quenching potencies of environmental bacteria in controlling biofilm of food spoilage bacteria.

ABSTRACT:

Objectives

This research aims to investigate anti-quorum sensing and antibiofilm activity of supernatants from environmental bacteria against the biofilm formed by food spoilage bacteria such as Bacillus cereus, Bacillus subtilis, and Shewanella putrefaciens.

Results

Supernatants were generated from ten environmental bacteria isolates (A19, A30, A32, A40, B10, B212, C1, J70, J73, and T152), with four isolates (A19, A32, A40, B212) showed anti-quorum sensing activity against Chromobacterium violaceum wild type as indicator bacteria. In inhibition and destruction assays, the highest percentage inhibition of 81.42% and 81.33% by B10 and B212, respectively, against B. cereus and J73 against B. subtilis was recorded at 87.45%. While A32, T152, and C1 performed the highest destruc
