Laboratory Investigations on the Effects of Bacteria on Fine-Grained Soils

Over the years, the field of geotechnical engineering focused on physical, chemical and mechanical aspects of the geomaterials. However, recent developments in environmental geotechnics have highlighted the impact of biological processes on geo-materials and their performance. Also, the present day geotechnical problems favour biological interventions to develop eco-friendly and sustainable technology. In view of this, the present study is a preliminary investigation on the impact of microbial loading on fine-grained soils. In addition, a protocol has been developed to establish ‘bio-geo interface’ between bacteria and the geo-material. However, long term studies are demanded in this direction for in-depth understanding of the mechanism for development of prospective application.
