One of the lactic acid bacteria that has potential to produce crude bacteriocin is Pediococcus acidilactici BK01, which result isolated from Bekasam. Crude Bacteriocin BK01 a high-temperature resistance 121°C, indicated by antibacterial activity E. coli O15: H7 and S.aureus ATCC25923 extensive pH stability against Escherechia sensitive proteolytic enzymes. still shows during 30 days storage at ...

Obtaining healthy food, free from chemical or synthetic additives, is a major challenge. In this study, we developed preservation method using essential oils and evaluated their effect on multidrug resistant pathogenic Gram-negative bacteria. Different concentrations (1%,0.1%,0.17% 0.35%) of Thyme oil black seed were employed in study against E. coli A. hydrophila soft cheese. The used at conce...

Protein-based edible films have received consideration attention in recent years because of their advantages, including their use as edible packaging materials, over the synthetic films. In addition, protein-based edible films can also be used for the individual packaging of small portions of food, particularly products that are not currently individually packaged for practical reasons, such as...

Preservative treatment of wood has a long history in the United States and throughout the world. Even the early settlers to the New World in the 17th century used wood preservatives to protect homes and other structures. The treated wood industry in the United States is evolving as new products emerge, technology advances, and environmental concerns increase. Recently, chromated copper arsenate...

PURPOSE The toxicity of antiglaucoma medications to ocular surface cells has been evaluated extensively; however, the toxicity to corneal endothelial cells (CECs) remains elusive. Our aim is to evaluate the toxicity of antiglaucoma medications to CECs using an in vitro toxicity assay. METHODS Primary cultures of human (H) CECs derived from eye bank specimens were established. Following exposu...

ε-Poly-L-lysine (ε-PL) is a homopolymer linked by the peptide bond between the carboxylic and the epsilon amino group of adjacent lysine molecules. It is naturally occurring, water soluble, biodegradable, edible and nontoxic towards humans and environment. ε-PL shows a wide range of antimicrobial activity and is stable at high temperatures. This review focuses on various ε-PL producing strains,...

Sulfites are used as food preservatives and excessive sulfite might disturb the body systems including the brain. Curcumin shows protective effects on the nervous system toxicity. The present study aimed to evaluate the protective role of curcumin in sulfite-induced anxiety in rats. Male rats were divided into five groups. The rats in groups I to V received distilled water (vehicle of sulfite, ...

The interaction between sodium benzoate (SB) and calf thymus DNA in simulated physiological buffer (pH 7.4) using acridine orange (AO) dye as a fluorescence probe, was investigated by UV-Vis absorption, fluorescence and circular dichroism (CD) spectroscopy along with DNA melting studies and viscosity measurements. An expanded UV-Vis spectral data matrix was resolved by multivariate curve resolu...
