The EUBCE is the event in which the members of the bioenergy community can get a broad picture of the situation and trends emerging in today's market. The Conference provides a high-level scientific programme and parallel events which attract participants from a wide-ranging background: researchers, engineers, technologists, standards organisations, financial institutions, policy makers and decision makers. This event is supported by European and international organizations. The Technical Programme is coordinated by DG Joint Research Centre of the European Commission.

Hej Anna,Jag hoppas allt är bra. Jag undrar om du har möjlighet att sprida informationen om en konferens som anordnas i Luleå augusti nästa år till B4E maillista (genom att ta bort denna text och vidarebefordra emailet)? Vi har fått bra keynote-talare att komma (kolla http://www.ltu.se/saee2016) men vi behöver också många forskare som kommer för att presentera sina alster. Hör av dig om du har några frågor.HälsningarRobert Lundmark

Prof. Shinya Kajita (TUAT, Japan) will be coming to Umeå to give a seminar on his latest work strategies to modulate lignin in tree biomass on Thursday 24th September. His breakthrough strategy has been to use genes isolated from bacteria living off the lignin residues from pulp mill stream into poplar wood to modify in vivo the wood structure. Bio4Energy researchers who would like to discuss with Prof. Kajita on Thursday 24th September should contact This email address is being protected from spambots.

It is an aromatic polymer with different types of chemical linkage. The most abundant linkage unit in typical native dicot lignin is the β-aryl ether (β–O–4) unit, which accounts for over 50% of all units. The benzylic α-positions of β–O–4-units are usually hydroxy-substituted. The α-keto-β–O–4 units, with carbonyl groups at the benzylic positions, are also found in natural lignins at very low concentrations. These α-keto β–O–4 units can be cleaved under alkaline and/or oxidative conditions more easily and faster than the typical β–O–4-units with benzylic hydroxyl groups. Thus, increasing the abundance of α-keto-β–O–4 units as opposed to the typical α-hydroxy-β–O–4 units in the lignin backbone can contribute to a reduction in the cost and energy required for chemical pulping and biomass pretreatment processes in cellulosic ethanol production.Sphingobium sp. strain SYK-6 , a gram-negative bacterium, can utilize various monomeric and dimeric aromatic compounds that are intermediates in the lignin biosynthetic pathway, such as cinnamic acid, cinnamaldehyde, and β–O–4 dimers. In our previous studies, we isolated and characterized a lot of genes from the bacterium, which were involved in the degradation of these compounds. One of the genes, ligD, encodes Cα dehydrogenase, which catalyzes the first step in the cleavage of the ether bond of β–O–4 dimers. This enzyme oxidizes the alcohol group at benzyl position of the dimers and oligomers to the carbonyl group. Thus, in the present study, we introduced ligD into the plant genome and attempted to generate transgenic plants whose lignin can be easy to remove from the holocellulose fraction. Recombinant LigD , and transgenic Arabidopsis plants with ligD and their lignins have been characterized by chemical, biochemical, and genetic methods.Reference: Tsuji et al.
