Isolation and identification of a novel bacterium, Lactobacillus sakei subsp. dgh strain 5, and optimization of growth condition for highest antagonistic activity.

In the present study, we isolated Lactobacillus sakei strain DGH5 from raw beef meat. This bacterium plays an inhibitory effect against food-spoiling bacteria and food-borne pathogens, including Listeria monocytogenes, a gram-positive and pathogenic bacterium. Lactobacillus sakei strain DGH5 was identified through both phenotypical and biochemical tests accompanied with 16S rRNA sequence analysis.

Dual effect of curcumin targets reactive oxygen species, adenosine triphosphate contents and intermediate steps of mitochondria-mediated apoptosis in lung cancer cell lines.

Exposure to arsenic is one of the major causes of lung cancer due to production of Reactive Oxygen Species (ROS). Herbal medicine is a new approach used for prevention or treatment of cancers. Among various herbal compounds, a lot of attention has been paid to curcumin, as antioxidant, anti-proliferative, anti-carcinogenic and anti-tumor and pro-apoptotic properties of curcumin have been well studied.
