This study was undertaken to characterize the biofilm architecture of binary biofilms of and species and to assess their effect on the survival of during exposure to hypochlorite. Three strains, ATCC 19115 (Lm5), ATCC 19117 (Lm7), and Coleslaw (LmC), were selected and combined individually with three strains: (Lf), (Lb), and (Lp).

Selection and application of natural antimicrobials to control Clostridium perfringens in sous-vide chicken breasts inhibition of C. perfringens in sous-vide chicken.

Current consumer preferences for both clean label food ingredients and convenience-based foods has provided a unique opportunity to explore the application of novel natural food preservatives in sous vide products. The anaerobic environment and relatively low thermal processing of the sous vide process creates a favorable environment for the survival, germination, and outgrowth of spore-forming bacterium Clostridium perfringens. The aim of this study was to identify effective novel natural ingredient formulations against C.

Antimicrobial polyphenol-rich extracts: Applications and limitations in the food industry.

One of the common ways to prevent food spoilage throughout product's shelf life is by using artificial/synthetic preservatives. However, the growing negative perception of consumers over synthetic preservatives has encouraged the food industry to consider their natural alternatives. Plant extracts, increasingly recognized as consumer-friendly, represent a valuable source of active compounds, mostly polyphenols, with potent antimicrobial and antibiofilm activities.

The Effects of Eugenol, Trans-Cinnamaldehyde, Citronellol, and Terpineol on Biofilm Control as Assessed by Culture-Dependent and -Independent Methods.

Bacterial biofilms contribute to problems with preserving food hygiene, jeopardizing any conventional intervention method used by the food industry. Hence, the approach of using essential oil (EO) compounds effective in biofilm control has considerable merit and deserves in-depth research. In this study, the effect of selected EO compounds (eugenol, trans-cinnamaldehyde, citronellol, and terpineol) was assessed on biofilm control by plate count, resazurin assay, and Syto 9/PI (-/propidium iodide) staining coupled with flow cytometry (FCM) and confocal laser scanning microscopy (CLSM).

Gender-related metabolic outcomes of laparoscopic sleeve gastrectomy in 6-month follow-up.

Introduction: Laparoscopic sleeve gastrectomy (LSG) is recently a leading method in surgical treatment of morbid obesity. The metabolic outcome of intervention may be a result of many factors such as age, gender, preoperative weight loss and dietary restrictions.

Aim: To evaluate gender-related differences in the results of LSG in 6-month follow-up.

The effect of ginger rhizome and refrigerated storage time on the quality of pasteurized canned meat.

The effect of ginger rhizome, in comparison with sodium ascorbate and butylated hydroxytoluene, and storage time at 5℃ on the quality of pasteurized canned meat was studied. Ginger rhizome was as effective as sodium ascorbate in inhibiting lipid oxidation. The canned meat with ginger rhizome was characterized by a lighter color and a lower contribution of redness than the remaining products.
