These results suggest that rhodopsin-possessing prokaryotes lacking known retinal biosynthesis genes also have functional rhodopsins.A nitrous oxide (N2O)-consuming bacterium isolated from farmland soil actively consumed N2O under high pH conditions. An acetylene inhibition assay did not show the denitrification of N2 to N2O by this bacterium. When N2O was injected as the only nitrogen source, this bacterium did not assimilate N2O. A polymerase chain reaction demonstrated that this bacterium did not have the typical nosZ gene. This bacterium belonged to Chitinophagaceae, but did not belong to known families that include bacteria with the atypical nosZ. This is the first study to show that a non-denitrifier actively reduces N2O, even under high pH conditions.The recent outbreak of coronavirus disease 2019 (COVID-19) was declared a pandemic by the World Health Organization on March 11, 2020. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19, primarily involves the respiratory system with viral pneumonia as a predominant manifestation. In addition, SARS-CoV-2 has various cardiovascular manifestations which increase morbidity and mortality in COVID-19. Patients with underlying cardiovascular diseases and conventional cardiovascular risk factors are predisposed for COVID-19 with worse prognosis. The possible mechanisms of cardiovascular injury are endothelial dysfunction, diffuse microangiopathy with thrombosis and increased angiotensin II levels. Hyperinflammation in the myocardium can result in acute coronary syndrome, myocarditis, heart failure, cardiac arrhythmias and sudden death. The high level of cardiac troponins and natriuretic peptides in the early course of COVID-19 reflects an acute myocardial injury. The comple
