Assessing the influence of the carbon oxidation-reduction state on organic pollutant biodegradation in algal-bacterial photobioreactors [PDF]
, 2011 The influence of the carbon oxidation-reduction state (CORS) of organic pollutants on their biodegradation in enclosed algal-bacterial photobioreactors was evaluated using a consortium of enriched wild-type methanotrophic bacteria and microalgae. Methane,

pH sensing via bicarbonate-regulated ‘soluble’ adenylyl cyclase (sAC)
Frontiers in Physiology, 2013 Soluble adenylyl cyclase (sAC) is a source of the second messenger cyclic adenosine 3',5' monophosphate (cAMP). sAC is directly regulated by bicarbonate (HCO3-) ions. In living cells, HCO3- ions are in nearly instantaneous equilibrium with carbon

Using small molecules to facilitate exchange of bicarbonate and chloride anions across liposomal membranes [PDF]
, 2009 Bicarbonate is involved in a wide range of biological processes, which include respiration, regulation of intracellular pH and fertilization. In this study we use a combination of NMR spectroscopy and ion-selective electrode techniques to show that the ...

The effects of hyperglycaemic hypoxia on rectification in rat dorsal root axons [PDF]
, 1994 1. Electrotonic responses to 150 ms current pulses were recorded from isolated rat dorsal roots incubated for at least 3 h with either normal (5 mM) or high (25 mM) D-glucose solutions, and with either normal (25 mM) or low (5 mM) bicarbonate ...

Controlling shell-side crystal nucleation in a gas-liquid membrane contactor for simultaneous ammonium bicarbonate recovery and biogas upgrading [PDF]
, 2014 A gas–liquid hollow fibre membrane contactor (HFMC) process has been introduced for carbon dioxide (CO2) separation from biogas where aqueous ammonia (NH3) is used to chemically enhance CO2 absorption and initiate heterogeneous nucleation of the reaction
