Biodiversity works both ways
The influence of biodiversity on the functioning of ecosystems has been a focus for extensive research over the last decade. In the July issue of Ecology Letters, Gamfeldt, Hillebrand and Jonsson show that changes in consumer species richness within a simple food chain of microbial organisms affected both the biomass of consumers and their prey. The results show that loss of biodiversity can change production both up and down the food chain. (2005-06-10)

What can ice reveal about fire?
Scientists studying a column of Antarctic ice spanning 650 years have found evidence for fluctuations in biomass burning -- the consumption of wood, peat and other materials in wildfires, cooking fires and communal fires -- in the Southern Hemisphere. (2010-12-03)

Predator-prey pattern consistent across diverse ecosystems
Ecological communities around the world are richly varied, but a new study finds that many of these diverse communities follow an unexpected, yet consistent pattern: where prey are abundant, there are not proportionally more predators. (2015-09-03)

Light energy and biomass can be converted to diesel fuel and hydrogen
A research group led by Professor WANG Feng at the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences recently developed a method to produce diesel fuel and hydrogen by exploiting light energy (solar energy or artificial light energy) and biomass-derived feedstocks.

Hydrogen distribution not an option in biomass gasification
When using fuel cells to generate electricity from biomass, the best approach is to do so centrally, in combination with a gas turbine. The production and subsequent distribution of hydrogen is an inefficient process. This is the view of Richard Toonssen, who will defend his doctoral dissertation on this subject at TU Delft in the Netherlands on Thursday, July 8. (2010-07-08)

Sustainable gas from 'roasted' wood is a feasible option

CO2 emissions from biomass combustion
CO2 emissions resulting from bioenergy production have traditionally been excluded from most emission inventories and environmental impact studies because bioenergy is carbon- and climate-neutral as long as CO2 emissions from biofuel combustion are sequestered by growing biomass. Its climate impact has not therefore been considered. An article in the current issue of Global Change Biology Bioenergy proposes a new method to account for CO2 emissions from biomass combustion in bioenergy systems. (2011-03-16)

Researchers look at lower-cost alternative protein source for pig diets
Threonine is an indispensable amino acid, which is often provided in supplement form in swine diets. With US production of crystalline amino acids increasing, more co-products from amino acid production are becoming available, and these co-products can also be fed to pigs. Researchers at the University of Illinois are investigating a co-product of synthetic threonine as a lower-cost alternative protein source to fish meal. (2015-06-11)

Green fuel versus black gold
A life cycle assessment of growing crops for fuel as opposed to refining and using fossil fuels has revealed that substitution of gasoline by bioethanol converted from energy crops has considerable potential for rendering our society more sustainable, according to a Japanese study published in the International Journal of Foresight and Innovation Policy. (2012-02-24)

New method for measuring biomass reveals fish stocks are more stable than widely believed
Fish and marine species are among the most threatened wildlife on earth, due partly to over exploitation by fishing fleets. Yet there are differences in assessing trends in worldwide fishing stocks which, researchers writing in Conservation Biology argue, stem from inappropriate use of time trends in catches. (2011-04-28)

Turning over a new leaf for future energy supplies
A global energy supply based on biomass grown to generate electricity and produce fuel is a real possibility. According to Prof. Juergen O. Metzger from Carl von Ossietzky University of Oldenburg in Germany and Prof. Aloys Huettermann from the University of Goettingen in Germany, it is both a sustainable and economical scenario, contrary to current thinking which suggests it is unrealistic. Their findings are published online this week in Springer's journal, Naturwissenschaften. (2008-12-15)

Neither more food nor better food -- still, fish biomass increases
To increase the biomass of fish, contemporary ecological theory predicts that either the amount of food or the quality of the food has to increase. In a recent experiment, researchers at Umeå University doubled the fish biomass under identical food supply and food quality by only controlling how much of total food supply that was channeled to juvenile and adult fish, respectively. The results have major implications for the exploitation (harvest) of fish populations and the coexistence of predatory fish and their prey. (2015-03-16)

Nagoya University chemists turn metal catalysis on its head for a sustainable future
Nagoya University team used high-valent transition metal catalysts for an unconventional hydrogenation of carboxylic acid groups, common to biomass feedstocks. The high-valent catalysts showed good selectivity under mild conditions. (2017-06-27)

Better planning required if EU is to meet energy targets
The EU has set itself a target to increase the proportion of renewable energy to 20 per cent by the year 2020. Over the same period, greenhouse gas emissions are to decrease to 20 per cent below 1990 levels. However, are the current European bioenergy initiatives sufficiently consistent and coherent to meet these targets? Niina Kautto is a researcher at the International Institute for Industrial Environmental Economics at Lund University. (2011-09-27)

Harnessing gut fungi of herbivores to break down biomass

Ecology insights improve plant biomass degradation by microorganisms
Microbes are widely used to break down plant biomass into sugars, which can be used as sustainable building blocks for novel biocompounds. Getting the right microbial community for this process is still a matter of trial and error. New insights by University of Groningen microbial ecologist Diego Javier Jiménez and colleagues could make a rational design possible. They argue this point in an opinion paper published in the journal Trends in Microbiology on June 22. (2017-06-22)

Context affects opinion about novel energy sources
Opinions people have about innovations are influenced by the context in which they form their opinion. For example, opinions about a novel energy source like biomass are influenced by thoughts regarding other energy sources. The less knowledge, interest or time people have, the stronger this effect. Sustainable energy options must therefore be promoted in the right context, says Dutch researcher Wouter van den Hoogen. (2007-07-12)

The commercialization of these enzymes has now begun in the Netherlands. (2013-01-08)

Seaweed as biofuel? Metabolic engineering makes it a viable option
Is red seaweed a viable future biofuel? Now that a University of Illinois metabolic engineer has developed a strain of yeast that can make short work of fermenting galactose, the answer is an unequivocal yes. Yong-Su Jin and his colleagues have recently identified three genes in Saccharomyces cerevisiae, the microbe most often used to ferment the sugars, whose overexpression increased galactose fermentation by 250 percent when compared to a control strain. (2010-12-15)

Dutch government could do more to promote sustainable energy
Dutch researcher Simona Negro discovered that seven key factors exert a major influence on the success or failure of sustainable energy in the Netherlands.

Plant stems and leaves are always proportional to roots
Cornell and University of Arizona researchers have found that the mass of a plant's leaves and stems is proportional to that of its roots in a mathematically predictable way, regardless of species or habitat. Biologists can now estimate how much biomass is underground by looking at the stems and leaves above ground. (2002-02-22)
