All About Efflux Pumps

Bacterial Multidrug Efflux Pumps: Much More Than Antibiotic Resistance Determinants SUMMARY: Efflux pumps are found in all organisms; they play an important role in helping the cells pump out toxins, heavy metals, and in the case of antibiotic resistant bacteria, antibiotics! This article talks about how efflux pumps work, other ways that they are used… Continue reading All About Efflux Pumps

Taking Methane Production Into Account

Climate-driven shifts in sediment chemistry enhance methane production in northern lakes SUMMARY: Different types of plant material decay and produce different amounts of methane. Methane is a more potent greenhouse gas compared to CO2 and decomposes into CO2 in the atmosphere. This study compared methane production of various types of plants. Plant material was collected… Continue reading Taking Methane Production Into Account

Metabolizing Acetaldehyde

Acetaldehyde production and metabolism by human indigenous and probiotic Lactobacillus and Bifidobacterium strains. (NOT OPEN ACCESS) SUMMARY: In order to turn ethanol into acetaldehyde, the enzyme alcohol dehydrogenase requires both a zinc atom and NAD+. This study looks at the levels of NAD+ in Lactobacillus and Bifidobacteria after incubating them in ethanol and acetaldehyde, in… Continue reading Metabolizing Acetaldehyde
