“…Inflammatory bowel diseases (IBD), characterized by rectal bleeding, diarrhea, intestinal motility disorder, and colonic shortening, are linked with colonic chronic inflammation [ 1 , 2 ]. Recently, Intestinal macrophages and dendritic cells have been indicated to involve in the initiation of inflammation in IBD through inappropriate responses to enteric microbial stimuli, inefficient clearance of microbes from host tissues, and impaired transition from appropriate proinflammatory responses to anti-inflammatory responses [ 3 – 5 ].…”

BackgroundAdiponectin, a protein hormone produced by adipose tissues, exhibits anti-inflammatory functions in various models. This study was investigated the effects of adiponectin on dextran sodium sulfate (DSS)-colonic injury, inflammation, apoptosis, and intestinal barrier dysfunction in Caco-2 cell and mice.Materials and methodsThe results showed that DSS caused inflammatory response and intestinal barrier dysfunction in vitro and in vivo. Adiponectin injection alleviated colonic injury and rectal bleeding in mice. Meanwhile, adiponectin downregulated colonic IL-1β and TNF-α expressions and regulated apoptosis relative genes to attenuate DSS-induced colonic inflammation and apoptosis. Adiponectin markedly reduced serum lipopolysaccharide concentration, a biomarker for intestinal integrity, and enhanced colonic expression of tight junctions (ZO-1 and occludin). The in vitro data further demonstrated that adiponectin alleviated DSS-induced proinflammatory cytokines production and the increased permeability in Caco-2 cells.ConclusionAdiponectin plays a beneficial role in DSS-induced inflammation via alleviating apoptosis and improving intestinal barrier integrity.

“…Although differences in the antimicrobial activity have been reported, both hydroxytyrosol [86][87][88][89] and oleuropein [90][91][92] play a central role in the antimicrobial activity of Olea europaea polyphenols. Particularly for hydroxytyrosol, the antimicrobial effect in different bacteria was tested against the growth of both Gram-negative (Aeromonas hydrophila, E. coli, Erwinia carotovora, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella typhimurium, Shigella sonnei, S. aureus, and Yersinia enterocolitica) and Gram-positive bacteria (Kocuria rhizophila, L. monocytogenes, and Pediococcus acidilactici).…”

“…In the case of oleuropein, contrasting results have been reported in terms of the effect against Gram-negative and Gram-positive bacteria. For instance, the study carried out by Dominciano et al [90] evaluated the antimicrobial effect of oleuropein and reported that the inhibition zone obtained against E. coli was smaller than that obtained for S. aureus. Similarly, Yuan et al [92] obtained the same result using an oleuropein extract against the same bacteria.…”

Phenolic Compounds Obtained from Olea europaea By-Products and Their Use to Improve the Quality and Shelf Life of Meat and Meat Products—A Review

Consumers are interested in consuming clean label foods. Replacing synthetic additives with natural alternatives (especially sources rich in polyphenols) is a valid solution to produce and also preserve foods, especially meat and meat products. Olea europaea leaves and olive pomace and wastewater contain polyphenols that can be explored in this context. In this review, we summarize the main aspects related to the phenolic composition, extraction conditions, antimicrobial potential, and antioxidant activity (in vitro and in vivo) of Olea europaea leaves, olive pomace and wastewater as well as their applications in the production of meat and meat products. This review found evidence that extracts and isolated polyphenols from the Olea europaea tree and olive processing by-products can be explored as natural antioxidant and antimicrobial additives to improve the preservation of meat and meat products. The polyphenols found in these residues (especially oleuropein, hydroxytyrosol and tyrosol) increased the redox state in the main meat-producing animals and, consequently, the oxidative stability of fresh meat obtained from these animals. Moreover, the extracts and isolated polyphenols also improved the shelf life of fresh meat and meat products (as additive and as active component in film) by delaying the growth of microorganisms and the progression of oxidative reactions during storage. The accumulated evidence supports further investigation as a natural additive to improve the preservation of reformulated muscle products and in the production of edible and sustainable films and coatings for fresh meat and meat products.

“…To assess the biofilmformation ability of the isolates, static biofilm systems may be used in view of the simplicity of experimental procedures and the possibility of standardization of conditions [3]. To this end, Microtiter Plate (MTP)-based assays can be used for assessing the ability of selected microbial strains to produce biofilms in vitro and estimate their resistance to biocides [24].…”

“…However, the MTP assay is not suitable for the biofilm on other material surfaces, such as stainless steel, glass, and aluminum. In this case, biofilm quantification should be accomplished by plate count methods, along with visualization by scanning electron microscopy or confocal laser scanning microscopy [14,24], among other techniques.…”

The ability of some pathogenic bacterial species to form biofilms on surfaces of equipment and utensils is of great concern to the food industry since they represent a continuous source of contamination in food processing environments. In this review, the factors involved in the formation of microbial biofilms are highlighted, along with a discussion on the preventive disinfection procedures recommended to avoid the attachment of microbial cells on surfaces of equipment and utensils in food processing areas. Relevant articles published in the last 10 years (2012-present) were selected in PubMed, Science Direct, and Google Scholar. Methods for assessing the adhesion and biofilm formation ability of strains isolated from surfaces in the food industry environment are also presented.
