As a new branch of MOFs which are composed of biocompatible metal ions and organic ligands, bio-metal-organic frameworks (bio-MOFs) have attracted much attention recently. Bio-MOFs feature multiple Lewis basic sites which have strong interaction with CO2 molecules, thus they have great potential in the separation and purification of gas mixtures containing CO2. In this work, molecular simulatio...

evaluation of carbon sequestration ability by chlorella vulgaris in water with different salinity expanded abstractintroductionnowadays, cultivation of microalgae in order to reduce co2 has gained attention all around the world. one of the outstanding features is that photosynthetic efficiency of microalgae is greater than that of terrestrial plants. carbon dioxide (co2) has been known as one o...

Whole-cell CO2 fixation and ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO) activity were determined in Rhodobacter sphaeroides wild-type and mutant strains. There is no obvious difference in the levels of whole-cell CO2 fixation for the wild type, a form I RubisCO deletion mutant, and a form II RubisCO deletion mutant. No ribulose 1,5-bisphosphate-dependent CO2 fixation was detected ...

This study used biogas from a wastewater treatment plant and bacterial community where methanotrophs, Methylophilus, ammonia-oxidizing bacteria clusters coexisted to propose an effective method for biological carbon fixation nitrogen removal in capture, utilization, storage (CCUS). Biogas was provided, instead of purified CH4, provide operation maintenance conditions bio-catalyst reaction effic...

Rising atmospheric CO2 and deliberate CO2 sequestration in the ocean change seawater carbonate chemistry in a similar way, lowering seawater pH, carbonate ion concentration and carbonate saturation state and increasing dissolved CO2 concentration. These changes affect marine plankton in various ways. On the organismal level, a moderate increase in CO2 facilitates photosynthetic carbon fixation ...

In nitrogen (N)-limited systems, the response of symbiotic N fixation to elevated atmospheric [CO2] may be an important determinant of ecosystem responses to this global change. Experimental tests of the effects of elevated [CO2] have not been consistent. Although rarely tested, differences among legume species and N supply may be important. In a field free-air CO2 enrichment (FACE) experiment,...

BACKGROUND The biomass yield of Chlorella PY-ZU1 drastically increased when cultivated under high CO2 condition compared with that cultivated under air condition. However, less attention has been given to the microalgae photosynthetic mechanisms response to different CO2 concentrations. The genetic reasons for the higher growth rate, CO2 fixation rate, and photosynthetic efficiency of microalga...

The potential of halotolerant algae isolated from natural resources was used to study CO2 fixation and algal lipid production. Biological fixation of CO2 in photobioreactor in presence of salinity is exploited. The CO2 concentration 1060 ppm gave the highest biomass yield (700 mg dry wt/l), the highest total lipid content (10.33%) with 80% of CO2 removal.

An integrated farming system is one of the alternatives for climatic change mitigation. This paper reports the application of corn-cattle based integrated farming system in Agrotechno Park Center of Palembang, and discusses its impact on CO2 fixation and the reduction of methane emissions. The study was based on the data of the first 6 yr from 2003 until 2009. The CO2 fixed in the soil and plan...
