Global climate change is expected to affect how plants respond to their physical and biological environments. In this study, we examined the effects of elevated CO2 ([CO2]) and low soil moisture on the physiological responses of mountain maple (Acer spicatum L.) seedlings to light availability. The seedlings were grown at ambient (392 µmol mol(-1)) and elevated (784 µmol mol(-1)) [CO2], low and...

Microalgal biomass production offers a number of advantages over conventional biomass production including, higher productivities, use of otherwise non­ productive land, reuse and recovery of waste nutrients, use of saline or brackish waters, and reuse of CO2 from power-plant flue-gas or similar sources. Microalgal biomass production and utilization offers potential for greenhouse gas (GHG) avo...

Carbon dioxide (CO2) emissions from burning fossil fuels play a crucial role in global warming/climate change. The effective removal of CO2 the point sources or atmosphere (CO2 capture), its conversion to value-added products utilization), and long-term geological storage, sequestration, has captured attention several researchers policymakers. This review paper illustrates all kinds capture/sep...

Anthropogenic effects on climate can be mitigated through various measures, among them being CO2 sequestration in geological media. Geological sinks for CO2 do not need any major new technological development; the technology exists and has been applied for other uses. The challenge is rather to identify the most appropriate methods and sites for long-term sequestration. There are several potent...

Succinate produced by microorganisms can replace currently used petroleum-based succinate but typically requires mono- or poly-saccharides as a feedstock. The cyanobacterium Synechocystis sp. PCC6803 can produce organic acids such as succinate from CO2 not supplemented with sugars under dark anoxic conditions using an unknown metabolic pathway. The TCA cycle in cyanobacteria branches into oxida...

An attempt was made to elucidate in Campylobacter spp. some of the physiologic characteristics that are reflected in the kinetics of CO2 formation from four 14C-labeled substrates. Campylobacter jejuni and C. coli were grown in a biphasic medium, and highly motile spiral cells were harvested at 12 h. Of the media evaluated for use in the metabolic tests, minimal essential medium without glutami...

Purpose: To determine the effects of temperature, pressure and extraction time on oil yield obtained from Polygonatum odoratum as well as the optimum processing conditions for supercritical carbon dioxide (CO2) extraction. Methods: Supercritical CO2 extraction technology was adopted in this experiment to study the process of extraction of volatile oil from Polygonatum odoratum while gas chromat...

Developing efficient methods for capture and controlled release of carbon dioxide is crucial to any carbon capture and utilization technology. Herein we present an approach using an organic semiconductor electrode to electrochemically capture dissolved CO2 in aqueous electrolytes. The process relies on electrochemical reduction of a thin film of a naphthalene bisimide derivative, 2,7-bis(4-(2-(...
