Harnessing the potential of Cupriavidus necator for CO capture from alcoholic fermentation and its bioconversion into poly(3-hydroxybutyrate).

The fermentation process in alcoholic beverage production converts sugars into ethanol and CO, releasing significant amounts of greenhouse gases. Here, Cupriavidus necator DSM 545 was grown autotrophically using gas derived from alcoholic fermentation, using a fed-batch bottle system. Nutrient starvation was applied to induce intracellular accumulation of poly(3-hydroxybutyrate) (PHB), a bioplastic polymer, for bioconversion of CO-rich waste gas into PHB.

The Triad of COVID-19 in Children: Acute COVID-19, Multisystem Inflammatory Syndrome, and Long COVID-Part II.

Coronavirus disease 2019 (COVID-19), which is now known to be caused by severe acute respiratory syndrome coronavirus 2, has been a public health threat since early 2020 and has affected millions of people worldwide. Many studies have now shown that this virus exhibits a milder infection in children compared to adults. Acute COVID-19 infection, multisystem inflammatory syndrome in children (MIS-C), and long COVID have been recently well-established in the pediatric population with a myriad of systemic manifestations.

Unveiling the fitness of Saccharomyces cerevisiae strains for lignocellulosic bioethanol: a genomic exploration through fermentation stress tests.

Lignocellulosic biomass holds significant promise as a substrate for bioethanol production, yet the financial viability of lignocellulosic fermentation poses challenges. The pre-treatment step needed for lignocellulosic substrates generates inhibitors that impede Saccharomyces cerevisiae growth, affecting the fermentation process and overall yield. In modern sugarcane-to-ethanol plants, a rapid succession of yeast strains occurs, with dominant strains prevailing.

The Triad of COVID-19 in Children: Acute COVID-19, Multisystem Inflammatory Syndrome, and Long COVID-Part I.

The coronavirus disease 2019 (COVID-19) originated in Wuhan, China, in late 2019. Within a span of a few months, it was deemed a global pandemic by the World Health Organization. It was first thought to affect the adult population, but soon after, cases of COVID-19 in children started emerging.

Integrated production of bioethanol and biomethane from rice waste using superior amylolytic recombinant yeast.

This study utilized a circular economy approach to convert unripe rice, a low-cost by-product of the rice milling industry, into biofuels using a biorefinery process. The recombinant yeast Saccharomyces cerevisiae ER T12.7 strain was tested for its ability to produce ethanol from unripe rice.
