Evaluation of inhibitory activity of some natural materials on biofilms formed on fresh fish cutting boards

الملخص EN

This research tried to evaluate the inhibitory activity of some natural, nontoxic, and inexpensive materials such as Iodized Salt (IS), Concentrated Natural Lemon Juice (CNLJ) and combination of both on one month old biofilm formed on 2cm2 of cutting board.

The treatment period ranged from 24 to 72 hours and the results shows that the combination of (IS+CNLJ) for 24 hours have a cidal effect on all microorganisms that formed biofilm on cutting board.

Streptococcus pneumonae, E.coli, Klebsiella spp., Proteus vulgaris, Salmonella spp., Staphylococcus spp., Pseudmonas spp., Listeria spp.

and Candida spp.

were isolated from cutting board, Knives, hands and inner surface of plastic container with different percentage ranging from 1.4%to 15.4%.
