The Photosynthetic Response of Jicama to Elevated CO2

Paper Reviewed Ravi, V., Pushpaleela, A., Raju, S., Gangadharan, B. and More, S.J. 2019. Evaluation of photosynthetic efficiency of yam bean (Pachyrhizus erosus L.) at saturating photon flux density under elevated carbon dioxide. Physiology and Molecular Biology of Plants 26: 189-194. The Mexican yam bean, or jicama (Pachyrhizus erosus), is an important edible legume that

Early growth phase and caffeine content response to recent and projected increases in atmospheric carbon dioxide in coffee (Coffea arabica and C. canephora)

By Fernando E. Vega et al. Abstract While [CO2] effects on growth and secondary chemistry are well characterized for annual plant species, little is known about perennials. Among perennials, production of Coffea arabica and C. canephora (robusta) have enormous economic importance worldwide. Three Arabica cultivars (Bourbon, Catimor, Typica) and robusta coffee were grown from germination

Bursting bubbles clear the way for desalination

Carbon dioxide bubbles could be a fast and environmentally friendly way to unclog seawater filters and keep the supply of drinking water flowing. Growing populations are increasing the global demand for drinking water, but natural sources of freshwater are shrinking. Extremely arid countries, such as Saudi Arabia, increasingly depend on desalinated seawater. The most effective

Science looks to wildfires to find missing source of carbonyl sulfide, link to plants’ carbon uptake

Carbonyl sulfide is a naturally occurring gas that can help scientists understand how much carbon dioxide plants take out of the atmosphere for photosynthesis. In a new study in Geophysical Research Letters, Lawrence Livermore National Laboratory (LLNL) scientists and collaborators looked at how much carbonyl sulfide (OCS) comes from forest fires and other burning biomass,

New Study: Coral Reefs Thrive Near Acidic Waters (pH ~6.0) Where Seafloor Vents Emit Up To 95,000 ppm CO2

By Kenneth Richard Though it’s believed the 130 ppm increase in atmospheric CO2 concentration since 1750 has caused the ocean waters to “acidify”, on a daily basis 50-380°C metallic acid enriched by CO2 concentrations reaching 60,000 to 95,000 ppm pours through seafloor vents. Nearby coral reefs “thrive” in these high-CO2 conditions. Image Source: PHYS.ORG 50

Quality controls, bias, and seasonality of CO2 columns in the Boreal Forest with OCO-2, TCCON, and EM27/SUN measurements

By Nichole Jacobs, et al. Abstract. Seasonal CO2 exchange in the Boreal Forest plays an important role in the global carbon budget and in driving interannual variability in seasonal cycles of atmospheric CO2. Satellite-based observations from polar orbiting satellites like the Orbiting Carbon Observatory-2 (OCO-2) offer an opportunity to characterize Boreal Forest seasonal cycles across

CO2 enrichment: Enhancing antioxidant, antibacterial and anticancer activities in Arthrospira platensis

By Sameh sassi Aydi et al. Highlights Algae production is one of the solutions for carbon sequestration. CO2 enrichment of the growth medium increased polyphenols, flavonoids and tannins. CO2 enrichment increased antioxidant activity (TAC, DPPH and FRAP). A. platensis showed stronger biological activity with CO2 enriched culture medium. A. platensis showed cytotoxic activities against OVCAR
