Figure 5 shows the breakdown of isolates based on their biofilm forming capabilities, PKS status, and isolate origin and the demonstration of biofilm formation was revealed through crystal violet staining in Figure 6. Overall, the PKS +ve isolates of CRC origin are strong to moderate biofilm producers. Table 6 shows the distribution of biofilm forming capabilities among K. pneumoniae isolates. This evidence concerns the gene ARAF and colorectal carcinoma.
