The extracts obtained from three Verbascum L. species (Verbascum olympicum Boiss., Verbascum prusianum Boiss., and Verbascum bombyciferum Boiss.) have been investigated for their antimicrobial activity. Growth inhibition, using the agar disc diffusion assay, was determined against Escherichia coli ATCC 11230, Micrococcus luteus La 2971, Staphylococcus aureus ATCC 6538P, Salmonella thyphi ATCC 19430, Klebsiella pneumoniae UC57, Pseudomonas aeroginosa ATCC 27893, Corynebacterium xerosis CCM 2824, Bacillus cereus ATCC 7064, Bacillus megaterium DSM 32, Mycobacterium smegmatis CCM 2067, Proteus vulgaris ATCC 8427, Candida albicans ATCC 10231, Rhodotorula rubra, andSaccharomyces cerevisiae ATCC 9763. We found that Verbascum L. species showed antimicrobial activity against the Gr(+) bacteria and yeasts, but no activity was seen against the Gr(-) bacteria used in this study.Pharmaceutical Biology Downloaded from informahealthcare.com by CDL-UC San Diego on 06/09/15For personal use only.

The protein mobilization from attached and detached seeds of Vicia faba L. cv. Eresen 87 (Fabaceae) was investigated. While the total soluble protein content decreased, the free amino acid content increased during the 7 days germination period. Among the three proteolytic enzymes, only endopeptidase activity was found to be affected by the removal of the embryonic axis. Leucine aminopeptidase activity was high at the beginning, then it decreased; carboxypeptidase activity reached the highest value at day 5. In order to examine the effects of plant growth regulators on detached cotyledons incubated with plant growth regulators [10 Ð4 m benzyladenine (BA), gibberellic acid (GA 3 ), indole acetic acid (IAA) and 10 Ð5 m abscisic acid (ABA)], only benzyladenine was found promotive on protein mobilization. Our results suggest that the removal of the embryonic axis in seeds of Vicia faba L. cv. Eresen 87 decreases protein mobilization and endopeptidase activity.
