Glucose-mediated catabolite repression in Sinorhizobium meliloti

, 2017
: Alfalfa plants and the bacteria Sinorhizobium meliloti interact in a symbiotic relationship in which the alfalfa plant receives a usable form of nitrogen, ammonia, to use as a fertilizer, while the bacteria receive a carbon and energy source from the ...

l-Arabinose triggers its own uptake via induction of the arabinose-specific Gal2p transporter in an industrial Saccharomyces cerevisiae strain

Biotechnology for Biofuels, 2018
Bioethanol production processes with Saccharomyces cerevisiae using lignocellulosic biomass as feedstock are challenged by the simultaneous utilization of pentose and hexose sugars from biomass hydrolysates.

Nutritional Heterogeneity Among Aspergillus fumigatus Strains Has Consequences for Virulence in a Strain- and Host-Dependent Manner

Frontiers in Microbiology, 2019
Acquisition and subsequent metabolism of different carbon and nitrogen sources have been shown to play an important role in virulence attributes of the fungal pathogen Aspergillus fumigatus, such as the secretion of host tissue-damaging proteases and ...

Carbon catabolite repression of penicillin biosynthesis by Penicillium chrysogenum.

The Journal of Antibiotics, 1984
The addition of glucose to batch cultures of Penicillium chrysogenum AS-P-78 reduced the biosynthesis of penicillin. This regulatory effect was also observed in penicillin biosynthesis by nitrogen-limited resting cells when cultures were previously grown in high concentrations of glucose.

Fructose Mediated Catabolite Repression in Sinorhizobium meliloti

, 2015
Plants are unable to utilize the N2 form found in the soil environment. Bacteria known as rhizobia are capable of fixing this nitrogen into a form useable by the plant and initiate a symbiotic relationship in the legume root.

Mutations in the Global Transcription Factor CRP/CAP: Insights from Experimental Evolution and Deep Sequencing

Computational and Structural Biotechnology Journal, 2019
The Escherichia coli cyclic AMP receptor protein (CRP or catabolite activator protein, CAP) provides a textbook example of bacterial transcriptional regulation and is one of the best studied transcription factors in biology.

Promoter-independent catabolite repression of the Bacillus subtilis gnt operon

, 1993
The mechanism underlying catabolite repression in Bacillus species remains unknown. A recent study of the promoter-independent catabolite repression of the gnt operon implicat-ed a consensus sequence (ATTGAAAG) in catabolite repression in the genus ...

Experimental evolution reveals an effective avenue to release catabolite repression via mutations in XylR

, 2017
Significance Lignocellulosic biomass is a promising renewable feedstock for microbial production of fuels and chemicals. D-glucose and D-xylose are the most abundant sugars in lignocellulosic materials.

Engineering mixed sugar metabolic channels in Pseudomonas putida to produce vanillic acid

Synthetic and Systems Biotechnology
Hydrolysis of lignocellulosic biomass produces the mixed sugars of glucose (60–70 %), xylose (20–30 %), and arabinose (2–20 %), etc. Using mixed sugars instead of pure glucose for microbial biosynthesis will reduce the cost of carbon source and maximize ...
