Therefore, the investigation of microbial mobility and their extensive distribution within crude oil is of paramount importance in MEOR. While microscale models have been valuable for studying bacterial strain behavior in reservoirs, they are typically limited to 2D representations of porous media, making them inadequate for simulating actual reservoir conditions. Consequently, there is a critical need for 3D models and dependable visualization methods to observe bacterial transport and metabolism within these complex reservoir environments.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and results<\/jats:title>\n                  <jats:p>Bacterial cellulose (bc) is a water-insoluble polysaccharide produced by bacteria that exhibits biocompatibility and biodegradability. It holds significant potential for applications in the field of MEOR as an effective means for selective plugging and spill prevention during oil displacement processes. Conditionally cellulose-producing strain, FY-07-G, with green fluorescent labeling, was engineered for enhanced oil recovery. 3D micro-visualization model was constructed to directly observe the metabolic activities of the target bacterial strain within porous media and to assess the plugging interactions between cellulose and the medium. Additionally, X-ray computed tomography (X-CT) technology was employed for a comprehensive analysis of the transport patterns of the target strain in oil reservoirs with varying permeabilities. The results indicated that FY-07-G, as a microorganism employing biopolymer-based plugging principles to enhance oil recovery, selectively targets and seals regions characterized by lower permeability and smaller pore spaces.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>This work provided valuable insights into the transport and metabolic behavior of MEOR strains and tackled the limitation of 2D models in faithfully replicating oil reservoir conditions, offering essential theoretical guidance and insights for the further application of oil-displacing bacterial strains in MEOR processes.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/jambio\/lxad281","type":"journal-article","created":{"date-parts":[[2023,12,7]],"date-time":"2023-12-07T20:42:47Z","timestamp":1701981767000},"source":"Crossref","is-referenced-by-count":6,"title":["Investigation of the transport and metabolic patterns of oil-displacing bacterium FY-07-G in the microcosm model using X-CT technology"],"prefix":"10.1093","volume":"134","author":[{"given":"Xueqing","family":"Zhao","sequence":"first","affiliation":[{"name":"Key Laboratory of Molecular Microbiology and Technology, Ministry of Education, College of Life Sciences, Nankai University , Tianjin 300071 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zitong","family":"Liao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Molecular Microbiology and Technology, Ministry of Education, College of Life Sciences, Nankai University , Tianjin 300071 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tongtong","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Molecular Microbiology and Technology, Ministry of Education, College of Life Sciences, Nankai University , Tianjin 300071 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Cheng","sequence":"additional","affiliation":[{"name":"Key Laboratory of Molecular Microbiology and Technology, Ministry of Education, College of Life Sciences, Nankai University , Tianjin 300071 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ge","family":"Gao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Molecular Microbiology and Technology, Ministry of Education, College of Life Sciences, Nankai University , Tianjin 300071 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mingbo","family":"Yang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Molecular Microbiology and Technology, Ministry of Education, College of Life Sciences, Nankai University , Tianjin 300071 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ting","family":"Ma","sequence":"additional","affiliation":[{"name":"Key Laboratory of Molecular Microbiology and Technology, Ministry of Education, College of Life Sciences, Nankai University , Tianjin 300071 , China"},{"name":"Tianjin Engineering Technology Center of Green Manufacturing Biobased Materials,College of Life Sciences, Nankai University , Tianjin 300071 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guoqiang","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Molecular Microbiology and Technology, Ministry of Education, College of Life Sciences, Nankai University , Tianjin 300071 , China"},{"name":"Tianjin Engineering Technology Center of Green Manufacturing Biobased Materials,College of Life Sciences, Nankai University , Tianjin 300071 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2023,12,6]]},"reference":[{"key":"2023121216580372300_bib1","doi-asserted-by":"crossref","first-page":"107928","DOI":"10.1016\/j.petrol.2020.107928","article-title":"Reservoir engineering of in-situ MEOR;
