The blue–white screen is a screening technique that allows for the rapid and convenient detection of recombinant bacteria in vector-based molecular cloning experiments. This method of screening is usually performed using a suitable bacterial strain, but other organisms such as yeast may also be used. DNA of transformation is ligated into a ...
The acidity of the dyes causes them to bind more strongly to the cell walls of the bacteria than to other cells or tissues. This results in the selective staining of only those cells that have a high density of cell wall material, such as acid-fast bacteria. [27] The Ziehl-Neelsen stain is a two step staining process. In the first step, the ...
Agar diffusion was first used by Martinus Beijerinck in 1889 to study the effect of auxins on bacterial growth. However, the method has been developed, refined and standardized by many scientists and scientific organizations over the years including George F. Reddish, Norman Heatley, James G. Vincent, [8] Alfred W. Bauer, William M.M. Kirby, John C. Sherris, [4] [5] Hans Martin Ericsson, the ...
A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions. Microbial cultures are foundational and basic diagnostic methods used as research tools in molecular biology .
Endospores can last for decades in multiple hard conditions, such as drying and freezing. This is because the DNA inside the endospore can survive over a long period. Most bacteria are unable to form endospores due to their high resistance, but some common species are the genera Bacillus ( over 100 species) and Clostridium (over 160 species). [2]
The FTC said organizers use cryptocurrency to fund the scams, and today, people report losing more money using cryptocurrency than any other method of payment. The scams work like this:

During last night's game there was an on-court skit that missed the mark. The skit included bad decision making and poor communication. Simply put, we turned the ball over and we apologize.
