Rejuvelac is a kind of grain water that was invented and promoted by Ann Wigmore, born in Cropos, Lithuania. The beverage is closely related to a traditional Romanian drink, called borș, a fermented wheat bran that can be used to make a sour soup called ciorbă or as the basis for vegan cheeses.

Optochin (or ethylhydrocupreine hydrochloride) is a derivative of quinine introduced in 1911 by Morgenroth and Levy with the intention to treat pneumococci infection. In very high dilutions, it inhibits the growth of representatives of all four groups of pneumococci in vitro. That is the main reason it is now used in bacteriology for the differentiation of Streptococcus pneumoniae, which is optochin-sensitive, from the other, resistant alpha-hemolytic streptococci, sometimes called the viridans streptococci because of the green colouration on blood agar around colonies.

In molecular biology, pertactin (PRN) is a highly immunogenic virulence factor of Bordetella pertussis, the bacterium that causes pertussis. Specifically, it is an outer membrane protein that promotes adhesion to tracheal epithelial cells. PRN is purified from Bordetella pertussis and is used for the vaccine production as one of the important components of acellular pertussis vaccine.

One of the serum substances which is part of the dissolution process of bacteria, the enzymes will promote the dissolution of the bacterial cell wall and cause the death of the bacteria.
