BME Seminars: Johan LILLEHAUG


The next BME seminar will take place on Friday 7th december with a lecture of Johan LILLEHAUG from the University of Bergen in Norway (see attached flyer). His conference is entitled "Can methane-oxidising bacteria help convert natural gas to food on our table?".


Methanotrophs are bacteria capable of using methane as the sole source of carbon and energy. This capacity places methanotrophic bacteria at the centre of interest for a long range of industrial exploitation and basic research. The ability of the bacterium Methylococcus capsulatus to oxidise methane has been used industrially to convert methane from natural gas to the single cell protein BioProtein®. M. capsulatus belongs to a group of bacteria known as methanotrophs, which are characterized by their limited catabolism where only methane or methanol can be utilized as carbon and energy source. M. capsulatus was the first methanotroph to have its genome fully sequenced. M. capsulatus grown by fermentation of natural gas, ammonia and mineral salts is a promising protein source. The spray-dried bacterial meal (BM) contains about 70% crude protein and 10% lipids and has a favorable amino acid composition with a high digestibility compared with the requirements of salmonids. Atlantic salmon fed diets containing up to 36% BM, partially replacing high-quality fish meal, obtained similar growth rates and feed intakes and improved feed efficiency compared to those fed a fish meal-based control diet. The seminar will focus on some basic aspects of M. capsulatus molecular biology.

The conference will take place at the Centre Universitaire des Saints Pères, 45 rue des Saints Pères,  75006 Paris, Amphi Lavoisier (3rd floor), from 13h30 to 15h00.

To avoid disturbing the talk, thank you for being on time.
