Antibiotic pollution: The forerunner of global health catastrophe?
AbstractThe rapid enhancement in the emergence of resistant bacteria occurring globally has endangered the efficacy of the conventional antibiotics causing threat to human at a large extent. Traces of antimicrobial drugs and their metabolites in various natural environments have resulted in enhancement of antimicrobial resistance (AMR) among the natural flora and fauna of the water resources. Contamination of the environment with antimicrobials encourages the bacteria to evolve ways to acquire competence which may result in the conversion of antibiotic susceptible strains to resistant bacteria. The spread of AMR varies fro...

Zeolite addition in microalgae Chlorella sp. for treatment of bacteria contaminated vinasse
This study demonstrated that the utilization of artificial vinasse digestate as a growing medium forC. pyrenoidosa resulted in growth limitation symptoms of microalgae, as a consequence of unfavorable interaction betweenC. pyrenoidosa and bacteria that already existed in the medium. This is indicated by low values of growth kinetics parameters, including specific growth rate (0.0259 d−1) and biomass productivity (0.51774 gL−1d−1) as compared to the reactor without bacteria in the medium. Therefore, adding a certain quantity of Zeolite to the reactor is a promising alternative for mitigating the negative effects o...
