Bacterial microcompartments are widespread, organelle-like structures that are made of a protein shell that surrounds and encloses various enzymes. provide a further level of organization; they are compartments within bacteria that are surrounded by polyhedral protein shells, rather than by lipid membranes. These "polyhedral organelles ...
The cell wall of both gram-positive and gram-negative bacteria is a tight covalently bound and cross-linked peptidoglycan network and essential for bacterial growth, cell division and cellular structure. Therefore, bacteria need enzymes that can cleave the cell wall during bacterial growth and cell division. The cell wall of bacteria is built ...
It contains a sprawling palace with vibrantly colored murals painted in Maya style. The nearby site of Xochitecatl was a more public ceremonial complex associated with Cacaxtla. Cacaxtla and Xochitecatl prospered 650–900 CE, probably controlling important trade routes through the region with an enclave population of no more than 10,000 people.
Colibactin is only produced by bacterial strains containing a polyketide synthase genomic island (pks) [1] or clb biosynthetic gene cluster. [4] About 20% of humans in high-income countries are colonized with E. coli that harbor the pks island. [5] [6] Colibactin forms DNA inter-strand cross-links by alkylation of adenine moieties on opposing ...

A detailed and comprehensive literature review on the various aspects of sophorolipids production (e.g. producing micro-organisms, bio-synthetic pathway, effect of medium components and other fermentation conditions and downstream process of sophorolipids is available in the published work of Van Bogaert et al. [5] [16] This work also discusses potential application of sophorolipids (and their ...
