PCR products of the genes encoding for biofilm production (a and b) identified in S. thoraltensis visualized on agarose gel electrophoresis. The expected molecular size of amplified DNA: 534 bp for brpA gene (a) and 397 bp for lmb gene (b). Lane 1 and 2: samples, Lane (L): DNA ladder, Lane (+ve): positive control and Lane (-ve): negative control.
