The Dept of Microbial Ecology in Lund started in 1972 when a research group specializing in ecological aspects of microorganisms moved from the Dept of Microbiology to the newly established Ecology Building. From the early 1970´s extensive research has been going on around the theme ”Soil microorganisms and control mechanisms in soil”. Two main research directions have been developed: Soil microorganisms and Nematophagous fungi. Both had received international recognition, and has been financed by research grants, mainly from the Swedish Natural Science Research Council.

Studies of the Mycorrhiza symbiosis started in the early 80's and gradually developed to its present strong position. During the 1980's the research group gradually became established as an independent division. A course in Microbial Ecology was given for the first time in 1979, and it became a separate division within the Dept of Ecology, with a separate professorship since 1987.

Ongoing research connected to South Asia

Håkan Wallander has worked on a research project entitled ”Influence of mycorrhizal fungi in stabilizing soils in areas subjected to erosion”.
Abstract: Many soils around the world are subjected to erosion, which causes deterioration of land and loss of productivity of soils. This project focuses on the role of mycorrhizal fungi in improving such soils in Nepal and Tunisia. Mycorrhizal fungi produces external mycelium that binds soil particles together to aggregates and they are efficient in taking up phosphorous from soils which is especially important as many soils subjected to erosion are low in phosphorous availability.

Methods developed by the researchers are used to quantify external mycorrhizal mycelium in the field and to investigate the role of mycorrhizal mycelium to counteract erosion. Preliminary studies in Nepal have revealed a positive relationship between arbuscular mycorrhizal colonization and P status of degraded soils. This suggests that the fungus have taken up poorly soluble P sources from the soil, which has been transferred to a more available form.
The Swedish International Development Cooperation Agency (SIDA) finances this project.
At the Development studies research conference held at Lund University in January 2003 Håkan Wallander presented the project in a paper called ”Can fungal hyphae be used to counteract soil degradation?” Read abstract!

Geeta Shrestha Vaidya was a Nepalese sandwich programme student, coming from the University of Kathmandu, who carried out her PhD Candidate at the department. In 2004 she spent two months at the department in Lund. She worked on a research project dealing with creating new vegetation on eroded soil, especially studying fungi living in symbiosis with roots of plants, and how these are affected by adding compost. Fungi are essential for a successful recolonialization of plants. Geeta Shrestha Vaidya has been working as a Scientific Officer in Nepal.

Erasmus Mundus External Cooperation Window Programme scholarship holders

A large number of Indian students, PhD candidates, post-docs and academic staff has come to Lund University during the academic year 2009-10, as scholarship holders through the Erasmus Mundus External Cooperation Window mobility programme Lot 15, coordinated by Lund University. This programme was announced in 2008, and out of a total mobility of 320 persons, 53 Indian students, researchers and academic staff were selected to come specically to Lund University. More information about the EMECW programme lot 15 (from 2009 renamed to be one out of four programmes under the mobility lot 13).

One of the scholarship holders, PhD candidate Firoz Hussain Shah, with a Degree of Master of Philosophy (M.Phil) in Biotechnology from Delhi University. He was selected for the Dept. of Microbial Ecology, where he will be supervised by Prof. Anders Tunlid and Associate professor Tomas Johansson. His primary research interest is Enzymes and proteins secreted by ectomycorrhizal fungi, related transcriptome and the genes, role in C-sequestration in forest soils. The methods he uses are Secretome and gene expression analysis.

Another PhD guest student admitted through the EMECW programme is Pramod Kamble, working on a thesis dealing with soil ecology. The title is ”Studies on Nutrient Limitation for Bacterial and Fungal Growth in Soil”. Mr. Kamble comes from the Pravara Institute of Medical Sciences in Loni, Maharashtra, India. At Lund University, he is supervised by Prof. Erland Bååth.
