The fungus Aspergillus nidulans reduces nitrate to ammonium and simultaneously oxidizes ethanol to acetate to generate ATP under hypoxic conditions in a mechanism called ammonia fermentation (Takasaki, K. et al.. J. Biol. Chem. 2004, 279, 12414-12420). To elucidate the mechanism, the fungus was cultured under normoxic and hypoxic (ammonia fermenting)(More)
Hypoxia imposes stress on filamentous fungi that require oxygen to proliferate. Global transcription analysis of Aspergillus oryzae grown under hypoxic conditions found that the expression of about 50% of 4,244 affected genes was either induced or repressed more than 2-fold. A comparison of these genes with the hypoxically regulated genes of Aspergillus(More)
Aromatic polymers include novel and extant functional materials although none has been produced from biotic building blocks derived from primary biomass glucose. Here we screened microbial aromatic metabolites, engineered bacterial metabolism and fermented the aromatic lactic acid derivative β-phenyllactic acid (PhLA). We expressed the Wickerhamia(More)
Cinnamic acid (CA) is the chemical basis for bulk production of flavoring reagents and chemical intermediates, and it can be fermented from biomass. Phenylalanine ammonia lyase (PAL) has been used exclusively in the bacterial fermentation of sugar biomass in which the fermentation intermediate phenylalanine is deaminated to CA. Here, we designed an(More)
We report the draft genome sequence of Microbacterium sp. strain HM58-2, which produces hydrazidase, an enzyme hydrolyzing acylhydrazides. The estimated genome size is 3.9 Mb. Genome sequence information of this strain will help to identify an assimilating mechanism of nonnatural compounds in this strain and to develop ecological applications.
Structural investigation of polymers by various available analytical methods is important in order to correlate the structure with polymer properties for which understanding of polymer structure is very important factor. The data presented here in this article shows the (1)H NMR spectra used for the characterization of prepared poly(amic acid)s (PAAs). It(More)
Aromatic amines containing an aminobenzene or an aniline moiety comprise versatile natural and artificial compounds including bioactive molecules and resources for advanced materials. However, a bio-production platform has not been implemented. Here we constructed a bacterial platform for para-substituted aminobenzene relatives of aromatic amines via(More)
Ethyl-2-hydroxy-4-methylpentanoate (ethyl leucate) contributes to a fruity flavor in Japanese sake. The mold Aspergillus oryzae synthesizes leucate from leucine and then the yeast Saccharomyces cerevisiae produces ethyl leucate from leucate during sake fermentation. Here, we investigated the enzyme involved in leucate synthesis by A. oryzae. The A. oryzae(More)
