Deletion of arcA, iclR, and tdcC in Escherichia coli to improve l‐threonine production

Biotechnology and applied biochemistry, 2019
l‐Threonine is an important amino acid supplemented in food, medicine, or feed. Starting from glucose, l‐threonine production in Escherichia coli involves the glycolysis, TCA cycle, and the l‐threonine biosynthetic pathway.

Citrate utilization under anaerobic environment in Escherichia coli is under direct control of Fnr and indirect control of ArcA and Fnr via CitA-CitB system.

Environmental Microbiology, 2020
Most Escherichia coli (E. coli) strains do not cause disease, naturally living in the lower intestine and is expelled into the environment within fecal matter. E. coli can utilize citrate under anaerobic conditions but not aerobic conditions.

Mutual interplay between ArcA and σE orchestrates envelope stress response in Shewanella oneidensis.

Environmental Microbiology, 2020
To survive and thrive in harsh and ever-changing environments, intricate mechanisms have evolved for bacterial cells to monitor perturbations impacting the integrity of their envelope and to mount an appropriate response to contain or repair the damage ...

Activation of regulator ArcA in the presence of hypochlorite in Salmonella enterica serovar Typhimurium.

Biochimie, 2020
Oxidative stress is the main mechanism behind efficient disinfectants, causing damage in bacterial macromolecules. Importantly, bacteria activate resistance mechanisms in response to damage generated by oxidative stress.

Arcas Swainson 1832

2019
Arcas Swainson, 1832 Type species: Papilio imperialis Cramer The species currently placed in Arcas have been recognized as a distinct and widespread Neotropical group for more than a century (Godman & Salvin 1887 –1901; Draudt 1919 –1920). Nicolay (1971) first revised the genus, recognizing seven species.
