Oxygen requirement of photosynthetic CO2 assimilation

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1980
In the absence of electron acceptors and of oxygen a proton gradient was supported across thylakoid membranes of intact spinach chloroplasts by far-red illumination. It was decreased by red light. Inhibition by red light indicates effective control of cyclic electron flow by Photosystem II.

CO2 mineralization induced by fungal nitrate assimilation

Bioresource Technology, 2011
Formation of CaCO3 induced by fungal physiological activities is a potential way to sequestrate atmospheric CO2 in ecosystem. Alternaria sp. is a saprophytic fungus isolated from a forest soil. We examined the precipitation of CaCO3 induced by the fungus in response to different levels of Ca(NO3)2 or CaCl2 in agar media, and the biogenesis of CaCO3 was

Regulation of CO2 Assimilation During Photoinhibition

1990
At high irradiance photosynthesis is limited by CO2 assimilation and more light is absorbed than can be effectively used to drive photosynthesis. Dissipation of surplus excitation energy is essential because excessive excitation leads to the light-induced loss of thylakoid efficiency called photoinhibition.

CO2 Assimilation by Chloroplasts illuminated on Filter Paper

Nature, 1970
CHLOROPLAST suspensions from Spinacea oleracea or Pisum sativum assimilate CO2 in the light at rates comparable with those observed with intact leaves1–3. With most preparations the major photosynthetic products are phosphoglyceric acid (PGA) and dihydroxyacetone phosphate (DHAP)2,4,5.

Inhibition of CO2 Assimilation by Supraoptimal CO2: Effect of Light and Temperature

Australian Journal of Plant Physiology, 1983
In cotton the rate of CO2 assimilation, at O2 partial pressures up to 200 mbar, increased to a maximum and then declined as the intercellular partial pressure of CO2 was increased. The specific intercellular partial pressure of CO2 at which rate of assimilation began to decline depended on the environmental conditions. At 19 mbar partial pressure of O2
