“…Ameliorasi dolomit juga dapat meningkatkan Corganik tanah. Ameliorasi dolomit memberikan keuntungan dalam pembentukan C-organik tanah melalui proses fiksasi mikrobial (Xiao et al 2016) oleh mikrob fotoautotrof seperti cyanobacteria maupun mikrob kemoautotrof, seperti carbon-monoxideoxidizing bacteria yang dapat mengasimilasi CO2 menjadi C-seluler (Wang et al 2014) untuk selanjutnya menyumbang dan meningkatkan C-organik tanah. Lignit tersusun atas asam humik, asam fulvik, dan turunannya yang dapat menyumbang C organik tanah dan mengurangi fitotoksisitas Al 3+ dan Fe 3+ (Gerke 1993).…”

Phytotoxicity of soil aluminum (Al), both directly to the plant growth as well as indirectly through the increase of soil potential acidity, is closely related to the occurrence of various soil soluble-Al species. Amongst them, Al3+ and monomeric-Al species are the primary causes of Al phytotoxicity in soils with high Al content. This study was aimed to evaluate the effects of soil amelioration with dolomite and base-activated lignite (BAL) on changes in soluble-Al species and other soil chemical properties, and vegetative growth of soybean (Glycine max Merr) on Ultisol of Jasinga (Al-dd 16,03 cmol(+)/kg). A green house experiment was conducted by applying a Completely Randomized Design with dolomite and BAL amelioration as the treatments, each with three levels of repectively 0, 1, 1,5 x exchangeable-Al and 0, 2,5, 5 tons BAL ha-1, and three replications. The ameliorants were incubated at field capacity of soil moisture content for one week before planting soybean for one month. Soil soluble-Al speciation was carried out using colorimetric aluminon method to determine concentrations of total soluble-Al, monomeric-Al, and polymeric-Al species. Monomeric-Al were further speciated into inorganic monomeric-Al and organic monomeric-Al species. The results revealed that only dolomite amelioration that significantly increased soil pH-H2O, pH-KCl, Ca- dd, Na-dd, and decreased exchangeable-Al concentration, except for those of all soluble-Al species that only showed a decreasing trend. Soil exchangeable-Al that was negatively and significantly correlated with soybean measure parameters were plant height, root length, total roots and shoots wet and dry weights, as well as Ca concentration. These results indicated that soil Al phytotoxicity evaluation could be relied on the result of routine analysis on soil exchangeable-Al concentration. Keywords: exchangeable-Al, inorganic monomeric-Al, organic monomeric-Al, polymeric-Al

“…The CAs can speed up the entire mineralization process by catalyzing the hydration of dissolved CO 2 into bicarbonate i.e., the reaction 2 at a faster rate (biomineralization). The addition of dolomite and K-feldspar to the soil can further enhance carbon sequestration in soil (Xiao et al, 2016 ). Use of CA as a potential biocatalyst has caught the attention of many researchers and much work has been done on exploring the possibilities of using this “Nature's own catalyst” for CCS (Farrell, 2011 ; Alvizo et al, 2014 ).…”

All the leading cities in the world are slowly becoming inhospitable for human life with global warming playing havoc with the living conditions. Biomineralization of carbon dioxide using carbonic anhydrase (CA) is one of the most economical methods for mitigating global warming. The burning of fossil fuels results in the emission of large quantities of flue gas. The temperature of flue gas is quite high. Alkaline conditions are necessary for CaCO3 precipitation in the mineralization process. In order to use CAs for biomimetic carbon sequestration, thermo-alkali-stable CAs are, therefore, essential. CAs must be stable in the presence of various flue gas contaminants too. The extreme environments on earth harbor a variety of polyextremophilic microbes that are rich sources of thermo-alkali-stable CAs. CAs are the fastest among the known enzymes, which are of six basic types with no apparent sequence homology, thus represent an elegant example of convergent evolution. The current review focuses on the utility of thermo-alkali-stable CAs in biomineralization based strategies. A variety of roles that CAs play in various living organisms, the use of CA inhibitors as drug targets and strategies for overproduction of CAs to meet the demand are also briefly discussed.

“…The results suggested that the addition of the minerals can not only facilitate the fixation of organic and inorganic carbons in the soil, but is also able to improve the soil properties and facilitate the growth of the plant. Moreover, the addition of K-feldspar can increase the amount of available potassium in the soil to a significant extent (Xiao et al, 2016c).…”
