Antibacterial activity of crude seed extracts of Buchholzia coriacea E. on some pathogenic bacteria
The antibacterial efficacy of hot water and methanol extracts of dried seeds of Buchholzia coriacea against Escherichia coli, Staphylococcus aureus, Salmonella typhimurium, Bacillus cereus, and Vibrio cholerae were determined using the Agar-gel diffusion method. The minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and phytochemistry of the extracts were also evaluated. Results obtained...

Photosynthetic properties of the protoplasts from Bryopsis hypnoides Lamouroux. during the early regeneration process
The scanning electronic microphotograph (SEM), photosynthetic oxygen evolution rate and excitation spectra at liquid nitrogen temperature (77 K) of the protoplasts from Bryopsis hypnoides were determined at the early regeneration period (12 h). SEM revealed an existence of the tight aggregation; cell membrane and wall were about 10 min, 6 and 12 h respectively, after the culture. Oxygen evolution rate decreased slowly...
