Antigen 43 (Ag43) is a surface-displayed autotransporter protein of Escherichia coli.By virtue of its self-association characteristics, this protein is able to mediate autoaggregation and flocculation of E. coli cells in static cultures. Additionally, surface display of Ag43 is associated with a distinct frizzy colony morphology in E. coli.Here we show that Ag43 can be expressed in a

The E. coli K-12 reference strain BD1428 exhibits different colony morphotypes. We have previously demonstrated that phase-variable expression of Ag43 is directly involved in this phenomenon. Escherichia coli is commonly found in the lower intestine of warm-blooded organisms (endotherms).

E coli colony morphology

Escherichia coli is commonly found in the lower intestine of warm-blooded organisms (endotherms). Most E. coli strains are harmless, but some, such as serotype O157:H7, can cause serious food poisoning in humans.

E coli colony morphology

They typically have a cell volume of 0.6-0.7 μm, most of which is filled by the cytoplasm. Grow an E. coli quality control strain for 18-24 hours on a MacConkey agar at 35-37°C with ~5% CO2 (or in a candle-jar). Observe the MacConkey for specific colony morphology. As a sterility test, incubate an uninoculated plate for 48 hours at 35-37°C with ~5% CO2 (or in a candle-jar).

To confirm that the altered phenotype was a result of Can functionality, an empty vector lacking can (pBBR1empty) was transformed into E. coli SH4888; this transformation did not rescue the carbon dioxide-dependent phenotype ( Fig. 1 D). 2016-11-01 · Scanning electron microscopy studies on morphology of E. coli harboring pBHR68 and CRISPRi systems targeting various ftsZ gene sites, respectively. E. coli (pBHR68+CRISPRi systems) were cultivated in Luria Bertani medium containing 2% (w/v) glucose at 37 ºC for 48 h under induction of aTc after 12 h as described in Section 2. Most E. coli (about 97%) produce beta-glucuronidase which produces a blue precipitate associated with the colony indicated by the blue to red-blue colonies. The top film traps gas produced by the lactose fermenting coliforms and E. coli.
