Prebiotic aqueous reactions catalyzed by native nickel without hydrogen
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

Abstract Fishes experience thermal stress in their natural environment that can be caused by natural or anthropogenic factors and can directly affect their physiology. In this study, we developed a multispecies OpenArray™ qPCR (quantitative polymerase chain reaction) ‘chip’ to measure the effects of acute thermal stress on the mRNA response of ...

ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

ABSTRACT Microalgae are a highly diverse group of unicellular organisms that grow in a wide range of aquatic environments and are widely used as dietary supplements for both human and animal applications. Microalgae are rich in lipids, proteins, carbohydrates and other valuable bioactive components such as pigments, antioxidants and vitamins.
