WILEY 01/03/18 Bacterial attachment and biofilm formation on stainless steel surface and their in vitro inhibition by marine fungal extracts. This study evaluates anti‐biofilm activity of four extracts from marine fungi; Penicillium citrinum PR1T4, Sarocladium strictum PP2L4, Aspergillus sydowii PR3T13, and Aspergillus spp.
PR5T4 against Staphylococcus aureus, Listeria monocytogenes (ATCC 19115), Escherichia coli, and Salmonella typhi (ATCC 14028). The ability of bacterial cells to adhere, detach, and form biofilm on stainless steel surface were examined and ethyl acetate extract of the fungal culture (15 mg/ml) were tested for anti‐biofilm activity for 3, 6, 9, 12, and 15 days.
E. coli showed the highest ability to adhere (>8 log CFU/cm2) and lowest detachment (<4 log CFU/cm2) after 24, 48, and 72 hr. Extract PP2L4 had the highest anti‐biofilm activity against S. typhi (1.70 ± 0.04 log CFU/cm2). Fungal extracts, bacteria, and incubation period were significant factors and their interactions were significant. Practical applications. Rev. Inst. Med. trop. S.

Food-Safe Modification of Stainless Steel Food-Processing Surfaces to Reduce Bacterial Biofilms. Biofilm formation on stainless steel (SS) surfaces of food-processing plants, leading to food-borne illness outbreaks, is enabled by the attachment and confinement of pathogens within microscale cavities of surface roughness (grooves, scratches).
We report foodsafe oil-based slippery coatings (FOSCs) for food-processing surfaces that suppress bacterial adherence and biofilm formation by trapping residual oil lubricant within these surface cavities to block microbial growth. SS surfaces were chemically functionalized with alkylphosphonic acid to preferentially wet a layer of food-grade oil. FOSCs reduced the effective surface roughness, the adhesion of organic food residue, and bacteria. FOSCs significantly reduced Pseudomonas aeruginosa biofilm formation on standard roughness SS-316 by 5 log CFU cm–2, and by 3 log CFU cm–2 for mirror-finished SS. FOSCs also enhanced surface cleanability, which we measured by bacterial counts after conventional detergent cleaning.

Parks, Ph.D., and Mindy M. Brashears, Ph.D. Shiga toxin-producing Escherichia coli (STEC) are pathogens of concern across various products within the food industry, as they have been connected to a wide variety of outbreaks and recalls. Most of the scientific literature concerning the removal of attached STEC cells focuses on E. coli O157:H7, as it was the first STEC to be considered an adulterant in nonintact beef products in the United States after a large outbreak from undercooked ground beef patties in 1982.[1] Worldwide, non-O157 STEC strains are estimated to cause 20 to 50 percent of STEC-related infections.[2] A review of outbreaks from 1983 through 2002 found six serogroups (O26, O111, O103, O121, O145 and O45) to be the most common non-O157 STECs causing human illness in the United States.[3] With an estimated 70 percent of non-O157 STEC infections being caused by these serogroups, the U.S.

AFRICAN JOURNAL OF MICROBIOLOGY RESEARCH Vol.8(36), pp. 3347-3353 , September 2014 Action of sanitizers on Staphylococcus aureus biofilm on stainless steel and polypropylene surfaces. The interest of researchers in various areas has resulted in the investigation of different biofilm systems using a wide range of techniques. Biofilms are microbial communities consisting of mono or multi-species sessile cells, embedded in a matrix of extracellular polymers (exopolysaccharides-EPS) adhering to surfaces.
In the food industry, the existence of biofilms is quite problematic, being responsible for the economic loss and contamination of food. Consequently, research involving the characterization of the ability of microbial biofilm formation is relevant for the subsequent studies using sanitizing and antibiotic agents for prevention or remediation of surfaces with already formed biofilms.

Microorganisms have been evolving for approximately 4 billion years, and up to 2 billion years ago they were the only life forms on Earth.
