Large batch production of Galactooligosaccharides using β-glucosidase immobilized on chitosan-functionalized magnetic nanoparticle.

β-glucosidase (BglA) immobilization from Thermotoga maritima on magnetic nanoparticles (MNPs) functionalized with chitosan (Cs) were efficiently investigated to improve lactose conversion and galactooligosaccharides (GOS) production. We used a batch method in order to improve the conversion of lactose to GOS. The efficiency and yield of immobilization were 79% and immobilized BglA was effectively recycled via a magnetic separation procedure through a batch-wise GOS with no activity lessening.

The impact of COVID-19 on the provision of cardiac surgical services.

The global pandemic caused by COVID-19 has had a significant global impact on healthcare systems. One implication of this pandemic is the cancellation of elective cardiac surgeries and the centralization of services. As a result, hospitals in Europe, North America, and the United Kingdom have had to alter the services offered to patients to be able to cope with service provision for COVID infected patients.
