Comparative genomics study of industrial fungus seeks to better harness potential for biofuels applications

Green Car Congress

Aspergillus niger, shown here with its DNA lit up in green, is a fungus that can be used on an industrial scale to produce enzymes or chemicals such as citric acid. niger is thus a well understood fungal fermentation process. Aspergillus niger is an industrial workhorse for enzymes and small molecules such as organic acids.

Tohoku researchers develop efficient hydrodynamic reactor for pretreatment of biomass

Green Car Congress

For their study, the researchers used corn stover as the feedstock for the new HD-SP reactor as well as the US-SP process they had developed earlier, subjected the output to enzymatic saccharification using a mixture of cellulase from Trichoderma reesei and β-glucosidase from Aspergillus niger , and characterized the results. 5b04375.
