Utility of iron concentration two to four hours post ingestion in predicting toxicity.

Introduction: Iron products are widely available over the counter and have the potential to cause serious toxicity. Iron concentrations can be used to prognosticate and guide treatment during acute ingestions. Traditionally, a concentration of 350 μg/dL with symptoms, or 500 μg/dL without symptoms, is considered toxic and will likely need treatment to prevent decompensation.

Unravelling the hidden power of esterases for biomanufacturing of short-chain esters.

Microbial production of esters has recently garnered wide attention, but the current production metrics are low. Evidently, the ester precursors (organic acids and alcohols) can be accumulated at higher titers by microbes like Escherichia coli. Hence, we hypothesized that their 'direct esterification' using esterases will be efficient.

as an Efficient Omnivorous Microbial Host for the Bioconversion of Lignocellulosic Biomass.

has been successfully employed for the industrial production of amino acids and other bioproducts, partially due to its native ability to utilize a wide range of carbon substrates. We demonstrated as an efficient microbial host for utilizing diverse carbon substrates present in biomass hydrolysates, such as glucose, arabinose, and xylose, in addition to its natural ability to assimilate lignin-derived aromatics. As a case study to demonstrate its bioproduction capabilities, L-lactate was chosen as the primary fermentation end product along with acetate and succinate.
