Description of research and teaching

The main research topics of our  Fungal biology and biotechnology research unit are the      degradation of lignin and lignocellulose by wood-rotting white-rot fungi and litter decomposing fungi and by their oxidative and hydrolytic enzymes. We also study potential applications of these fungi and their lignin and cellulose degrading enzymes, e.g. in the pulp and paper industry and in the remediation of polluted soils and waste waters.

Lignocellulosic plant biomasses (wood and straw) contain 20-30% lignin, which makes it the second most abundant renewable organic compound on Earth. Lignin is presently the most unexploited renewable natural material the significance of which certainly increases, because many feedstock now produced from petroleum oil could be produced from plant lignin.

In nature lignin is degraded mostly by basidiomycetous white-rot and litter-decomposing fungi. The lignin-modifying enzymes lignin peroxidases (LiPs), manganese peroxidases (MnPs) and versatile peroxidases (VPs) are peroxidases while laccases use molecular oxygen as oxidant. Laccase was discovered already in the 1880’s but still its role in lignin degradation is unclear. We have recently thoroughly studied the expression and properties of laccases and peroxidases by two model white-rot basidiomycetes (Phlebia radiata and Physisporinus rivulosus (syn. Obba rivulosa, fruiting body in the picture above). The genome of Obba rivulosa was sequenced in June 2014 and it was the first fungus isolated from Finland, the genome of which was sequenced. In spite of advances in molecular characterisation of fungal enzymes we still do not have all of the factors for to understand how lignin is degraded in nature.

As an important microbial resource we have a large culture collection (Fungal Biotechnology Culture Collection FBCC) of about 2200 fungi, mainly basidiomycetes but also many hundreds ascomycetes recently isolated from agricultural fields. I am the Director of HAMBI Microbial Culture Collection from the autumn 2014.

Utilization of the whole plant biomass in biorefineries especially for fuel and feedstock chemicals is under an extensive investigation all over the world. Enzyme and fungi can be used to treat wood chips prior to pulping in a process called biopulping, and they can be used to bleach paper pulp in a process called biobleaching. These fungi and their enzymes can also be used to remove e.g. polyaromatic hydrocarbons (PAH), chlorinated compounds and hormone disrupting compounds such as bisphenol A, in a process called bioremediation. These biotechnological processes belong to industrial or white biotechnology, and fungi and their enzymes provide the basic biotechnical tools for this work.

Some of our recent or ongoing projects are

Teaching and administration

I am Professor in Environmental Biotechnology, University of Helsinki from 1997, invited two times for 5 year periods and then invited and nominated to permanent position from 01.01.2008. I am responsible professor for the major topic Biotechnology, orientation Microbial and Environmental Biotechnology, at the Faculty of Agriculture and Forestry, from 2004. The other teachers in biotechnology at the Division of Microbiology and Biotechnology are university lecturers Pauliina Lankinen (biotechnology) and Kristiina Hildén (microbial biotechnology).

We have at the Faculty of Agriculture and Forestry since 2004 a major topic, biotechnology, which is jointly arranged by three departments. I was 2004-2011 the chairperson of the board for the biotechnology major of the Faculty of Agriculture and Forestry. This education belonged 2004-2010 to the Helsinki region biotechnology education program (HEBIOT). From the autumn 2011 the new students were taken to the biotechnology major at the Faculty of Agriculture and Forestry. We have also Master’s Programme in Biotechnology (MBIOT). There are also 15 registered doctoral students in biotechnology on the orientation of microbial and environmental biotechnology. Until now, summer 2014, five doctoral dissertations have been defended.

Curriculum Vitae

I was invited 1997 as professor in environmental biotechnology at the Department of Food and Environmental Sciences (until 31.12.2009 at the Department of Applied Chemistry and Microbiology), and in 2002 for another 5-year period, and to permanent position from 1.1.2008. The research group (http://www.helsinki.fi/food-and-environment/research/groups/fungal_biotechnology.html) in October 2014 consists of the Principal Investigator (1), post doctorates (1), doctoral students (5), other researchers, undergraduate students, and trainees. Prof. Annele Hatakka and four university lecturers (Kristiina Hildén, Pauliina Lankinen, Taina Lundell, Kari Steffen) and the Academy Fellow (Jussi Heinonsalo) and their groups form the Fungal Biology and Biotechnology reserch unit and closely collaborate with each other. Hatakka’s group was in 2002-2007 a member of Center of Excellence “Microbial Resources Research Unit”, nominated by the Academy of Finland, A. Hatakka was the 2nd vice director of the unit. The group was a member of Center of Excellence “Microbial Resources Research Unit” (2002-07), A. Hatakka was the 2nd vice director of the unit.

 Before the professorship I have worked in different positions of the Academy of Finland for 24 years from 1972-1996, first at the Department of Microbiology, and from 1992 at the Department of Applied Chemistry and Microbiology. I worked 1.5 years as visiting scientist at STFI (The Swedish Forest Products Laboratory) in Stockholm, and shorter periods in UK and France. I was member of the government (senate, “konsistori”) of the University of Helsinki, 1992-1994, and the member of the Research Council for Biosciences and Environment, The Academy of Finland (2001-2003). I was also the vice director of the department in 2004-2006. I was a member of the board of EnSTe GS (Graduate School in Environmental Sciences and Technology) 2007-2014.

I have 112 journal articles and about 110 book chapters and congress proceedings articles, 4 patents, and I have presented about 60 oral presentations including several key note lectures, and participated congresses in about 30 countries. My h-index is 32, the sum of cites is 3,607, and the most cited paper is review Hatakka, A. 1994. FEMS Microbiol. Rev. 13:125-135, cited 540 times (15.10.2014, Web of Science). I have had extensive international cooperation, e.g. in EU project (2006-2010) Biorenew "White Biotechnology for added value products from renewable plant polymers” which had 26 partners. I have coordinated two INTAS projects, e.g. INTAS 03-51-5889 “Blue and non-blue laccases of basidiomycetes” (2004-2006). The other partners were from Italy and Russia (Prof. L. Golovleva, Pushchino), and we have cooperated with Prof. Golovleva in an Academy of Finland funded project (2008-2010). NICE (Nordic Innovation Center) funded a 3-year project LigniMatch (2007-2009) on Lignin as raw material for chemicals. I have cooperated with my former post doc Martin Hofrichter, presently professor in environmental biotechnology in IHIZ, Zittau, Germany, and we have about 20 joint referee publications. We have cooperated with Prof. Alexander Kapich, International Sakharov Environmental University, Minsk, Belarus. The group has every year visitors, students and trainees from Germany, Czech Republic, China, Spain etc.

I am responsible professor for the major topic Biotechnology, orientation Microbial and Environmental Biotechnology, at the Faculty of Agriculture and Forestry, from 2004. See my attached CV for more detailed information on scientific, educational and administrative achievements, and also a short description on the development of biotechnology education in the Faculty of Agriculture and Forestry, the founding of Helsinki Region Biotechnology Education Program (HEBIOT), M.Sc.
