biodegradable polysacharyd-based film was developed by incorporating pimpinella affinis essential oil (pao) into methyle cellulose (mc) at level of 0.5%, 1% and 1.5% v/v. then, its antimicrobial activity tested against 7 bacteria include staphylococcus aureus (ptcc 1431), pseudomonas aeruginosa (ptcc 1151), pseudomonas putida(ptcc 1691),esherichia coli (ptcc 3315), listeria monocytogenes (ptcc ...

Bacterial endospores are highly resistant structures that allow survival for long periods of time in adverse environments. The spore-forming Gram-positive bacterium Bacillus subtilis synthesizes a coat around the endospore during development composed of several assembled polypeptides. The role of these components of the spore coat remains unclear; however, some of them appear to be enzymes poss...
