Microfiltration (MF) and Ultrafiltration (UF) for Sewage and Surface Water Concentration for SARS‐CoV‐2 and Other Enveloped Viruses' Detection in Wastewater‐Based Epidemiology (WBE)

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT This study objective was to evaluate hollow fiber membranes for concentration of enveloped enteric viruses in sewage and surface water samples. Microfiltration (MF, 0.2 µm nominal pore size) and ultrafiltration (UF, 100 kDa molecular weight cut‐off) hollow fiber membranes were compared for the concentration of the bovine respiratory syncytial ...

Immobilization of Alginate Microbeads With Whole‐Cells Expressing Nitrilase for Continuous Nicotinic Acid Production in Chip Millireactor

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT The biocatalytic production of nicotinic acid using nitrilases has emerged as a promising alternative to conventional chemical synthesis, offering improved selectivity and environmental sustainability. In this study, we developed a continuous‐flow millireactor system employing Escherichia coli cells expressing a nitrilase from Paraburkholderia

Leishmaniasis: efflux pumps and chemoresistance

International Journal of Antimicrobial Agents, 2003
Resistance of parasitic protozoa such as Leishmania to therapeutic drugs continues to escalate in developing countries. Treatment programs for human leishmaniasis are still based on pentavalent antimonials but resistance to these compounds has been a persistent problem.

Mycobacterial efflux pumps and chemotherapeutic implications

International Journal of Antimicrobial Agents, 2003
The demonstration of the existence of active efflux pumps in mycobacteria raises the question of whether or not these can increase in number and activity rendering wild-type mycobacteria increasingly resistant to a given antibiotic. This could be a mechanism by which mutated resistant strains become better fit to the selective environment ...
