The emergence of multidrug and extensively drug-resistant pathogenic bacteria able to resist the action a wide range antibiotics is becoming growing problem for public health. search new compounds with potential help in reversion bacterial resistance plays an important role current medicinal chemistry research. Under this scope, efflux pumps are responsible antimicrobials, their inhibition coul...

The ozone-depleting and greenhouse gas, nitrous oxide (N2O), is mainly consumed by the microbially mediated anaerobic process, denitrification. N2O consumption is the last step in canonical denitrification, and is also the least O2 tolerant step. Community composition of total and active N2O consuming bacteria was analyzed based on total (DNA) and transcriptionally active (RNA) nitrous oxide re...

Food poisoning has been emerged as a worldwide health issue and related illness in both developed and developing countries confirms its significance as an important public health priority.In vitro antibacterialevaluationof nine fluoroquinolone derivatives against food borne bacteria including Gram-positive (Staphylococcus aureus) and Gram-negative (Salmonella enterica, Escherichia coli, Yersini...

In this study, the antimicrobial activity of crude extracts of flower, fruit, stem and leaf of Conocarpus erectus and purified tannins were evaluated against three fungi and seven Gram-positive, Gram-negative and acid-fast bacteria. While, by disc diffusion method, extracts of different parts of C.erectus were active only against Saccharomyces cerevisiae, purified tannins were active against Sa...

Bacteriocins and microcins are ribosomally synthesized antimicrobial peptides that are usually active against phylogenetically related bacteria. Thus, bacteriocins are active against Gram-positive while microcins are active against Gram-negative bacteria. The narrow spectrum of action generally displayed by bacteriocins from lactic acid bacteria represents an important limitation for the applic...
