- The chb operon in E. coli helps the bacteria use specific sugars like chitobiose and cellobiose, with the chbG gene playing a crucial role in this process.
- ChbG encodes a monodeacetylase essential for utilizing acetylated forms of chitooligosaccharides, while it is not needed for growth on non-acetylated forms like cellobiose.
- ChbG's activity is important for the chb promoter activation by the regulatory protein ChbR, and understanding chbG is significant in broader contexts, including its homologs linked to human gut development and diseases.
Article Synopsis
- Bacterial symbionts in nitrogen-fixing nodules of Mimosa pudica from North and South India matched closely with Ralstonia taiwanensis based on carbon-source usage and 16S rDNA sequences.
- Isolates from both regions displayed similar ARDRA patterns, but showed differences with the AluI enzyme, indicating genetic variation between the two populations.
- Analysis of nifH sequences suggests that nitrogen-fixing genes in these bacteria may have been transferred laterally from alpha-rhizobia to R. taiwanensis, while also indicating the existence of functional dinitrogenase reductase, though nitrogen-fixing activity was not observed under N-free conditions.
Azospirillum brasilense is a microaerophilic, plant growth-promoting bacterium, whose nitrogenase activity has been shown to be sensitive to salinity stress. Growth of A. brasilense in semi-solid medium showed that diazotrophic growth in N-free medium was relatively less sensitive to high NaCl concentrations (200-400 mM) than that in presence of NH4+.
