TL;DR: In this paper, the carbonic anhydrase (CA), a common enzyme of bacteria, promoted carbon dioxide hydration to release HCO3− and CO32− in the process of calcite precipitation; the pH increased from 7.2 to 8.9 as a result of the combination effect of the released ammonia by B. cereus MRR2 and the HCO 3− and carbon 32− ions originating from the CA reaction.
Journal ArticleDOI
The bio-precipitation of calcium and magnesium ions by free and immobilized Lysinibacillus fusiformis DB1-3 in the wastewater
Yan Huaxiao,Zuozhen Han,Hui Zhao,Juntong Pan,Yanhong Zhao,Maurice E. Tucker,Jingxuan Zhou,Xiaoyun Yan,Haiyan Yang,Di Fan +9 more
TL;DR: In this paper, a simple and environmentally friendly method applying biological processes to precipitate calcium (Ca) and magnesium (Mg) ions as carbonates and phosphate using free and immobilized Lysinibacillus fusiformis DB1-3 bacteria isolated from a petroleum sample.
Journal ArticleDOI
Extracellular and Intracellular Biomineralization Induced by Bacillus licheniformis DB1-9 at Different Mg/Ca Molar Ratios
Zuozhen Han,Gao Xiao,Hui Zhao,Maurice E. Tucker,Yanhong Zhao,Bi Zhenpeng,Juntong Pan,Guangzhen Wu,Yan Huaxiao +8 more
TL;DR: In this article, precipitation of carbonate minerals was induced by Bacillus licheniformis DB1-9 bacteria, (identity confirmed with its phylogenetic tree), to further explore the biomineralization mechanisms.
Journal ArticleDOI
Isolation of Leclercia adcarboxglata Strain JLS1 from Dolostone Sample and Characterization of its Induced Struvite Minerals
Han Zuozhen,Sun Bin,Hui Zhao,Yan Huaxiao,Han Mei,Zhao Yanyang,Meng Ruirui,Zhuang Dingxiang,Li Dan,Ma Yutong,Peiyu Ma,Juntong Pan +11 more
TL;DR: The results of the X-ray powder diffraction (XRD) analysis of the minerals revealed that the preferred orientation and lattice distortion were characteristic of struvite crystals as mentioned in this paper.
Journal ArticleDOI
Comparative study on thermal behaviors between micrites and thrombolites using thermogravimetric analysis
Zuozhen Han,Zhuang Dingxiang,Hui Zhao,Yan Huaxiao,Guangzhou Mao,Changhong Yao,Jiajia Wang,Bi Zhenpeng,Shan Guanghe,Juntong Pan,Xiaoxu Sun,Yifan Zhao,Yumo Yang +12 more
TL;DR: In this article, the comparative studies of thermal decomposition behavior between micrites and thrombolites were carefully investigated using thermogravimetric analyzer in nitrogen atmosphere at multi-heating rates of 5, 10, 20 and 30 Kmin−1 from 323.15 to 1273.15 K. This provided very important useful information for understanding the mechanisms of abiotic and biotic limestones formed in nature.
