Selective butyric acid production from CO and its upgrade to butanol in microbial electrosynthesis cells.

Microbial electrosynthesis (MES) is a promising carbon utilization technology, but the low-value products (i.e., acetate or methane) and the high electric power demand hinder its industrial adoption.

Microbial electrosynthesis of acetate from CO in three-chamber cells with gas diffusion biocathode under moderate saline conditions.

The industrial adoption of microbial electrosynthesis (MES) is hindered by high overpotentials deriving from low electrolyte conductivity and inefficient cell designs. In this study, a mixed microbial consortium originating from an anaerobic digester operated under saline conditions (∼13 g L NaCl) was adapted for acetate production from bicarbonate in galvanostatic (0.25 mA cm) H-type cells at 5, 10, 15, or 20 g L NaCl concentration.

Surgical management of chronic rhinosinusitis with nasal polyps under local anaesthesia: indications and results.

Objective: Our objective was to specify the indications and duration of effectiveness of Awake Patient Polyp Surgery (APPS) in Chronic Rhinosinusitis with Nasal Polyps (CRSwNP). Secondary objectives were to evaluate complications and Patient-Reported Experience (PREMs) and Outcome Measures (PROMs).

Methods: We collected information regarding sex, age, comorbidities and treatments.

CO in indoor environments: From environmental and health risk to potential renewable carbon source.

In the developed world, individuals spend most of their time indoors. Poor Indoor Air Quality (IAQ) has a wide range of effects on human health. The burden of disease associated with indoor air accounts for millions of premature deaths related to exposure to Indoor Air Pollutants (IAPs).

Boosting ethanol production rates from carbon dioxide in MES cells under optimal solventogenic conditions.

Microbial Electrosynthesis (MES) has been widely applied for acetic acid (HA) production from CO and electricity. Ethanol (EtOH) has a higher market value than HA, and wide application in industry and as a biofuel. However, it has only been obtained sporadically and at low concentrations, probably due to sub-optimal operating conditions.
