    A team of Bio4Energy scientists and partners have been acknowledged at a prestigious conference for their work to reduce the effect of toxic substances in the pre-treatment of biomass destined for conversion to advanced biofuels made using yeast or microbes to turn wood polymers into fuels.

    Their review article, Pre-treatment of lignocellulose: Formation of inhibitory by-products and strategies for minimising their effects, published in the Bioresource Technologyscientific journal, has not stopped receiving acclaim since its publication in 2016. At the time of New Horizons in Biotechnology Conference (NHBT-2019)—a conference given in India in November this year—results from the article had been mentioned 560 times in other scientific articles by researchers worldwide.

    This made the editorial board of Bioresource Technology decide to award the researcher with a diploma and a plaque for their Highly Downloaded Article 2019.

    “It is the most downloaded article steadily during the last two years and the most cited article of Bioresource Technology since 2016”, said This email address is being protected from spambots.

    “I think it helped that the review covered all three areas of pre-treatment, formation of inhibitors and strategies [designed to lessen] their effects”, Martín added, “and that the discussion included some new important inhibitors in terms of their effects. That is, compounds that form in small amounts, but which are very strong inhibitors”.

  • Bio4Energy's Flagship Training Is Back on Biorefinery Development via Pilots, Demonstration Units

    Bio4Energy’s on-location training course on pilot and demonstration facilities for developing world-class biorefinery technologies is set to start again in spring, in northern Sweden. PhD and postdoctoral students keen on experiencing first-hand the development of tomorrow’s biofuels, “green” chemicals or bio-based materials should apply. The start is in April 2022 and the application will open in February. 

    Industry professionals or consultants wanting inside on what it takes to develop successful biorefinery technology past the laboratory stage, via pilot and demonstration trials, are equally welcome to apply.

You get to experience the working atmosphere and you feel welcome at that”, said course coordinator This email address is being protected from spambots. You need JavaScript enabled to view it..

  • Deepening Ties Among Members Focus of Industrial Network Seminar by SP Processum, Bio4Energy

    SP Processum and Bio4Energy gave a joint seminar for the SP Processum member companies and Bio4Energy's Industrial Network, yesterday at Örnsköldsvik, Sweden. Seventy-five people from industry, business incubators, academia, research institutes, consultancies and regional and national Swedish authorities came, listened to presentations, workshopped and networked. The focus was on deepening and widening the cooperation between the actors in the network, to uphold and strengthen the position of northern Sweden as a leading region for development of biorefinery based on wood or organic waste. 

    Several speakers took the opportunity to reach out, or even to urge, members of northern Sweden's biorefinery business community to dare to take the step and cooperate to develop innovations.

    One said: "If you think the real reason I am here is to market my offer you are right... We are bringing in new technology and infrastructure and I am asking you: 'Shall we dance?'".

  • New Professor in Bio4Energy Wants to Reach Young People to Change World – Video

Photo by courtesy of the Swedish University of Agricultural Sciences.A Bio4Energy leader—and a recent professor—wants to give young people tools with which to change the world, moving to a bioeconomy from an economy dependent on materials and fuels based on petrochemicals.

    A professor at the Swedish University of Agricultural Sciences since this month, This email address is being protected from spambots. You need JavaScript enabled to view it. has been a platform leader in the research environment Bio4Energy since 2018. This means she is responsible for research and development on wood pre-processing, in the context of making renewable materials and fuels. Larsson is also the chief coordinator for the Bio4Energy Graduate School on the Innovative Use of Biomass.

    “I want to capture the commitment of young people to transform [what I perceive to be] the generalised feeling of hopelessness... in the face of climate change. We want to start from the idea of a future society in which the use of fossilised resources is minimal. And to create training that will give students tools to help shape the future,” she said.

    The work of the Bio4Energy platform Larsson leads rests on two legs. In terms of biorefinery—meaning the concept of making chemicals, fuels and materials from bio-based starting materials—her platform tackles the need to make these latter more like fossilised resources. Bio-based feedstock like wood is heterogenous, meaning that its composition varies greatly. Larsson’s platform, Bio4Energy Wood Pre-processing, adapts the woody materials to specific processes. She refers to this as the “problem-solving” leg of the work of the platform.

    The appointment comes at a pivotal time, since Bio4Energy is coming up to the close of its second programme period in 2020. Its funder, the Swedish government, is expected to decide this year whether to renew the funding for Sweden’s Strategic Research Environments (SRE), of which Bio4Energy is one.

    It will be up to the newly appointed threesome to lead Bio4Energy into the future.

    “We hope that wise decisions will be made and that the SRE initiative will be allowed to continue. We will have to await the arrival of political decision to know more about this”, said Jönsson, professor of Chemistry at UmU.

    Ever wished you had a voice in Brussels, to express your thoughts to European Union officials about what the EU should or should not do to promote the transition to a bioeconomy?

    If you are in the Scandinavian part of Bio4Energy's network, chances are that you do.

You need JavaScript enabled to view it. of the Bio4Energy Industrial Network received an e-mail from the European Commission to say he had been elected a member of the European Union Bioeconomy Stakeholder Panel. The Commission's research and innovation branch started up the panel in 2013 and now, with a newly elected membership for its second mandate, Sweden has no less than four representative on it.

    "That's breaking a record", to believe Matisons.

    Matisons is a well-known figure in forestry and biorefinery circles in northern Sweden. He has worked both as a scientist at the Swedish University of Agricultural Sciences and, more recently, as project leader with Biofuel Region, which organisation works to promote biorefinery development across northern Sweden.

  • Newly Discovered Compounds in Trees Carry Promise as High Value-added Products

    Bio4EnergyBurningCandle Anna Strom2021 400pxBio4Energy scientists say that newly discovered lipophilic compounds in wood, once better understood, could be turned into organic wax for making candles, cosmetics or even anti-inflammatory drugs. Photo by Anna Strom©2021. researchers have found a set of compounds in the wood of trees that have “apparently been overlooked” until now, and which the scientists believe could find use as organic wax in cosmetics, candles or as agents in anti-inflammatory drugs. Not only this, but the discovery and mapping of these fat-loving substances might inform the pulp and paper industry on how to avoid problems with clogging of machinery in biorefineries.

    The discovery by scientists at the Swedish University of Agricultural Sciences (SLU), was unveiled last week as the prestigious Swedish Research Council announced it would fund a three-year effort to lay bare ways in which these lipophilic compounds, found in the cell walls of trees, behave and interact with other components of the wood and how to extract them.

    In fact, the research team led by This email address is being protected from spambots.

    “These novel compounds are partially insoluble and partially contained within the extractives—the compounds that can reach ten per cent of wood dry weight”, professor Mellerowicz explained in an e-mail message to Bio4Energy Communications.

    Abstract [EN]                
    The evolutionary success of land plants was fostered by the acquisition of the xylem vascular tissue which conducts water and minerals upwards from the roots. The xylem tissue of flowering plants is composed of three main types of cells: the sap-conducting tracheary elements (TE), the fibres which provide mechanical support and the parenchyma cells which provide metabolic support to the tissue. Both the TEs and the fibres deposit thick polysaccharidic secondary cell walls (SCWs), reinforced by a rigid phenolic polymer called lignin. The cell walls of TEs form efficient water conducting hollow tubes after the TEs have undergone programmed cell death (PCD) and complete protoplast degradation as a part of their differentiation. The work presented in this thesis studied the regulation of TE PCD by characterizing the function of the candidate PCD regulator METACASPASE 9 (MC9) in Arabidopsis thaliana xylogenic cell suspensions. These cell suspensions can be externally induced to differentiate into a mix of TEs and parenchymatic non-TE cells, thus representing an ideal system to study the cellular processes of TE PCD. In this system, TEs with reduced expression of MC9 were shown to have increased levels of autophagy and to trigger the ectopic death of the non-TE cells. The viability of the non-TE cells could be restored by down-regulating autophagy specifically in the TEs with reduced MC9 expression. Therefore, this work showed that MC9 must tightly regulate the level of autophagy during TE PCD in order to prevent the TEs from becoming harmful to the non-TEs. Hence, this work demonstrated the existence of a cellular cooperation between the TEs and the surrounding parenchymatic cells during TE PCD. The potential cooperation between the TEs and the neighbouring parenchyma during the biosynthesis of lignin was also investigated. The cupin domain containing protein PIRIN2 was found to regulate TE lignification in a non-cell autonomous manner in Arabidopsis thaliana. More precisely, PIRIN2 was shown to function as an antagonist of positive transcriptional regulators of lignin biosynthetic genes in xylem parenchyma cells. Part of the transcriptional regulation by PIRIN2 involves chromatin modifications, which represent a new type of regulation of lignin biosynthesis. Because xylem constitutes the wood in tree species, this newly discovered regulation of non-cell autonomous lignification represents a potential target to modify lignin biosynthesis in order to overcome the recalcitrance of the woody biomass for the production of biofuels.
