Erythritol is a natural sugar abundant in fruits and fermentingfoods. Pathogenic bacterial strains that catabolize erythritolcontain four closely spaced genes, all involved in erythritolmetabolism. One of the four genes (eryD) encodes a productthat represses the expression of the other three genes. Erythritolcatabolism is stimulated by erythritol. Present a regulatorymodel to account for the regulation of erythritol catabolism insuch bacterial strains. Does this system appear to be underinducibleor repressible control?
Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.
Erythritol is a natural sugar abundant in fruits and fermenting
foods. Pathogenic bacterial strains that catabolize erythritol
contain four closely spaced genes, all involved in erythritol
that represses the expression of the other three genes. Erythritol
catabolism is stimulated by erythritol. Present a regulatory
model to account for the regulation of erythritol catabolism in
such bacterial strains. Does this system appear to be under
inducible
or repressible control?
