Since such interfaces usually connect two regions with very different hydraulic and mineral properties, the resulting flow patterns, the prevailing transport mechanisms or the distribution of chemical species can have far-reaching consequences for microbial activity. Using two examples \u2013 one natural and one technical \u2013 numerical models will be used to determine the prerequisites and relevant mechanisms of the microbial processes under consideration. Numerical simulations atthe millimetre scale (with pore-network models) and at the metre scale will be carried out for both examples. The numerical models required for further research will be developed and tested as part of the IFF project.<\/p>\n\n\n\n<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<figure class=\"wp-block-image size-large is-style-default\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"319\" src=\"https:\/\/www.hsu-hh.de\/hmech\/wp-content\/uploads\/sites\/845\/2022\/09\/iff-1024x319.png\" data-credit=\"Anozie Ebigbo\" alt=\"Biomass at material interface in subsurface\" class=\"wp-image-1169\" srcset=\"https:\/\/www.hsu-hh.de\/hmech\/wp-content\/uploads\/sites\/845\/2022\/09\/iff-1024x319.png 1024w, https:\/\/www.hsu-hh.de\/hmech\/wp-content\/uploads\/sites\/845\/2022\/09\/iff-300x93.png 300w, https:\/\/www.hsu-hh.de\/hmech\/wp-content\/uploads\/sites\/845\/2022\/09\/iff-768x239.png 768w, https:\/\/www.hsu-hh.de\/hmech\/wp-content\/uploads\/sites\/845\/2022\/09\/iff-1536x479.png 1536w, https:\/\/www.hsu-hh.de\/hmech\/wp-content\/uploads\/sites\/845\/2022\/09\/iff-1100x343.png 1100w, https:\/\/www.hsu-hh.de\/hmech\/wp-content\/uploads\/sites\/845\/2022\/09\/iff.png 1961w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<p>Mechanism for accumulation and persistence of biomass in the deep subsurface at<br>the shale\u2013sandstone interface.<\/p>\n<\/div>\n<\/div>\n\n\n\n<p><strong>Funding<\/strong>: Internal research funding (Interne Forschungsf\u00f6rderung, IFF) of <abbr title=\"Helmut Schmidt Universit\u00e4t\">HSU<\/abbr>; 01.10.2022 &#8211; 30.06.2024<\/p>\n\n\n\n<p><strong>Researcher<\/strong>: Emna Mejri; <strong>PI<\/strong>: Anozie Ebigbo<\/p>\n\n\n\n<p><strong>Project partners<\/strong>: Simon Gregory (British Geological Survey, UK),&nbsp;Chao-Zhong Qin (Chongqing University, China)<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h3 class=\"wp-block-heading\">Project-related presentations:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mejri, E.: Numerical Modeling of Microbially Induced Calcite Precipitation at Sandstone-Cement Interface.
