Catabolite repression control protein antagonist, a novel player in Pseudomonas aeruginosa carbon catabolite repression control [PDF]
In the opportunistic human pathogen Pseudomonas aeruginosa (Pae), carbon catabolite repression (CCR) orchestrates the hierarchical utilization of N and C sources, and impacts virulence, antibiotic resistance and biofilm development.

Development of an auto-inducible expression system by nitrogen sources switching based on the nitrogen catabolite repression regulation [PDF]
Background The construction of protein expression systems is mainly focused on carbon catabolite repression and quorum-sensing systems. However, each of these regulatory modes has an inherent flaw, which is difficult to overcome.

Removing carbon catabolite repression in Parageobacillus thermoglucosidasius DSM 2542 [PDF]
Parageobacillus thermoglucosidasius is a thermophilic bacterium of interest for lignocellulosic biomass fermentation. However, carbon catabolite repression (CCR) hinders co-utilization of pentoses and hexoses in the biomass substrate.

Preliminary study on the effect of catabolite repression gene knockout on p-nitrophenol degradation in Pseudomonas putida DLL-E4 [PDF]
P-nitrophenol (PNP) is a carcinogenic, teratogenic, and mutagenic compound that can cause serious harm to the environment. A strain of Pseudomonas putida DLL-E4, can efficiently degrade PNP in a complex process that is influenced by many factors ...

When metabolic prowess is too much of a good thing: how carbon catabolite repression and metabolic versatility impede production of esterified α,ω-diols in Pseudomonas putida KT2440 [PDF]
Background Medium-chain-length α,ω-diols (mcl-diols) are important building blocks in polymer production. Recently, microbial mcl-diol production from alkanes was achieved in E. coli (albeit at low rates) using the alkane monooxygenase system AlkBGTL and

Atmospheric hydrogen consumption is regulated by glycerol-mediated catabolite repression in mycobacteria [PDF]
Consumption of atmospheric hydrogen (H2) enables diverse aerobic microorganisms to grow and persist in resource-deprived environments. In the aerobic saprophyte Mycobacterium smegmatis, hydrogen oxidation is catalyzed by two differentially expressed ...

Modulating Chitinase in the QS Biosensor Strain CV026: Do Not Forget to Release Carbon Catabolite Repression. Comment on Deryabin et al. Quorum Sensing in Chromobacterium subtsugae ATCC 31532 (Formerly Chromobacterium violaceum ATCC 31532): Transcriptomic and Genomic Analyses. Microorganisms 2025, 13, 1021 [PDF]
Chitinolytic activity is a well-documented phenotype controlled by quorum sensing (QS) in Chromobacterium strains but also regulated by carbon catabolite repression mechanisms.

What are the signals that control catabolite repression in Pseudomonas? [PDF]
Metabolically versatile bacteria exhibit a global regulatory response known as carbon catabolite repression (CCR), which prioritizes some carbon sources over others when all are present in sufficient amounts.

Utilization of carbon catabolite repression for efficiently biotransformation of anthraquinone O-glucuronides by Streptomyces coeruleorubidus DM [PDF]
Carbon catabolite repression (CCR) is a highly conserved mechanism that regulates carbon source utilization in Streptomyces. CCR has a negative impact on secondary metabolite fermentation, both in industrial and research settings.
