The antibacterial activity of water and ethanol extract of Camellia sinensis(L.) Kuntze were examined against Lactobacillus acidophilus and Streptococcus mutans. Antibacterial activity was investigated by paper diffusion test and Minimum inhibitory concentration. Water extract of C. sinensis produce zones of inhibition 6mm-18mm and 8-27mm respectively against Lactobacillus acidophilus and Streptococcus mutans. Ethanol extracts of C....

Semi-synthetic -lactam antibiotics are the largest group of antibiotics used worldwide. Penicillin V Acylase (Cephalosporin acylase) is a crucial enzyme for the development of new enzymatic pathways leading to the production of semi-synthetic cephalosporins. 7-amino desacetoxy cephalosporanic acid (7-ADCA) is an important intermediate in these pathways. Large quantities of this compound are needed, but the traditional production routes are time-consuming, expensive and/or polluting.Pakistan being an agricultural country has potential resources of biomass for their exploitation in the...
