Microbial dynamics, chemical profile, and bioactive potential of diverse Egyptian marine environments from archaeological wood to soda lake.

Halophilic archaea are a unique group of microorganisms that thrive in high-salt environments, exhibiting remarkable adaptations to survive extreme conditions. Archaeological wood and El-Hamra Lake serve as a substrate for a diverse range of microorganisms, including archaea, although the exact role of archaea in archaeological wood biodeterioration remains unclear. The morphological and chemical characterizations of archaeological wood were evaluated using FTIR, SEM, and EDX.

The role of Algerian ethanolic extract in inhibiting the growth of breast cancer cells by inducing apoptosis in a p53- dependent pathway.

Background: , a member of the Ephedraceae family, was used to treat different diseases and it might be shown a strong efficacy to inhibit cancer cell lines.

Methods: Due to the limited research available about this plant, the objective of this research was to evaluate the antioxidant, cytotoxic and apoptotic effects of ethanolic extract (EAEE), against different human cancer cell lines.

Results: EAEE inhibited the growth of the liver (HepG2), breast (MCF-7), and colon cancer cells (Caco-2).

Antibacterial and anticancer activity of ε-poly-L-lysine (ε-PL) produced by a marine Bacillus subtilis sp.

A marine Bacillus subtilis SDNS was isolated from sea water in Alexandria and identified using 16S rDNA sequence analysis. The bacterium produced a compound active against a number of gram negativeve bacteria. Moreover, the anticancer activity of this bacterium was tested against three different human cell lines (Hela S3, HepG2 and CaCo).
