Elucidating bacteria’s roles in ant fungal gardens

Leafcutter ants cultivate fungal gardens that serve as their primary food source. Working toward the goal of harnessing novel enzymes for breaking down plant biomass to produce cellulosic biofuels, Great Lakes Bioenergy Research Center (GLBRC) researchers have been studying the process by which the fungi break down the plant leaves harvested by the ants and… [Read More]

A toolkit for T. reesei

The availability of an organism’s genome sequence is useful for improving downstream applications such as large-scale biofuel production, but it is only the first step on this path. In the case of the fungus Trichoderma reesei, whose genome sequence was published by the DOE JGI in 2008, the cellulases in T. reesei have multiple industrial… [Read More]

A.niger genome project on The Bioenergy Site

Published online ahead of print May 4, 2011 in Genome Research, a team led by Scott Baker of the Pacific Northwest National Laboratory compared the genome sequences of two Aspergillus niger strains to, among other things, better harness its industrial potential in biofuels applications. As more than a million tons of citric acid are produced annually, the production… [Read More]

Fungal lessons for large-scale “green” chemical production

The chemical compound citric acid has been produced on a large-scale basis for decades with the help of the filamentous fungus Aspergillus niger. The fungus also has enzymes that can be used to help break down plant cell walls for biofuel production, and it plays a key role in the carbon cycle. Aspergillus niger (Sue… [Read More]

Toward a Genomic Encyclopedia of Fungi

Fungi are key components of terrestrial ecosystems and help maintain the interactions between a myriad of species of animals, plants and bacteria that make up these environments. With the ability to thrive in a wide variety of ecological niches, fungi are essential to the global carbon cycle, and the enzymes and metabolites they produce are… [Read More]

Shewanella research on ScienceDaily

Researchers have completed the first thorough, system-level assessment of the diversity of an environmentally important genus of microbes known as Shewanella. Microbes belonging to that genus frequently participate in bioremediation by confining and cleaning up contaminated areas in the environment. The team of researchers from the Georgia Institute of Technology, Michigan State University and the… [Read More]

T. reesei research on ISA’s InTech

During World War II, Trichoderma reesei frustrated American Army quartermasters in the South Pacific by speeding up the rate at which canvas supplies wore out. Now the same fungus is a key producer of industrial enzymes that break down biomass for biofuel production. In 50 short years, the fungus has gone from being the bane… [Read More]

T. reesei work on MycoRant

A recent post at sciencedaily.com, Fungal Map Of Mutations Key To Increasing Enzyme Production For Bioenergy Use, discussed once again the use of Trichoderma reesei as a possible biofuel producer. This time some work at Pacific Northwest National Laboratory (PNNL) was mentioned. “We want to understand the path that we’ve taken to high enzyme production… [Read More]

Shewanella research on Environmental Protection

Researchers have completed the first thorough, system-level assessment of the diversity of an environmentally important genus of microbes known as Shewanella. Microbes belonging to that genus are used to confine and clean up contaminated areas in the environment. The team of researchers from the Georgia Institute of Technology, Michigan State University and the Pacific Northwest… [Read More]

T. reesei research on R&D Daily

Now an international team of researchers led by scientists at the DOE Joint Genome Institute (JGI), the French applied research center IFP—particularly concerned with renewable resources and energies—and the Vienna Univ. of Technology (TU Vienna) provides the first genome-wide look at what these mutations are in order to understand just how cellulase production was first… [Read More]
