Hemicelluloses currently represent the largest polysaccharide fraction wasted in most
cellulosic ethanol pilot and demonstration plants around the world. The reasons are based …

Citric acid is regarded as a metabolite of energy metabolism, of which the concentration will
rise to appreciable amounts only under conditions of substantive metabolic imbalances …

Background The organic acid producer Aspergillus oryzae and Rhizopus delemar are able
to convert several alternative carbon sources to malic and fumaric acid. Thus, carbohydrate …

Abstract This Mini-Review summarizes the current knowledge on the biochemical and
physiological events leading to massive citric acid accumulation by Aspergillus niger under …

Citric acid is a commodity chemical produced and consumed throughout The World. It is
used mainly in the food and beverage industry, primarily as an acidulant. Although it is one …

Microbial fermentation was widely explored to produce malic acid. Previously, Aspergillus
niger has been successfully engineered, and a high titer of malic acid was achieved with …

In an attempt to provide a rational basis for the optimization of citric acid production by A.
niger, we developed a mathematical model of the metabolism of this filamentous fungus …

The creA gene of A. nidulans encodes a wide‐domain regulatory protein mediating carbon
catabolite repression. Northern blot analysis of creA mRNA revealed a complex expression …

Background The glucose dual-affinity transport system (low-and high-affinity) is a conserved
strategy used by microorganisms to cope with natural fluctuations in nutrient availability in …

A sugar-transporter-encoding gene, mstA, which is a member of the major facilitator
superfamily, has been cloned from a genomic DNA library of the filamentous fungus …
