Prodiginine Biosynthesis
The prodiginines are a family of red tripyrrole dyestuffs produced by Gammaproteobacteria (e.g. ''Serratia marcescens'') as well as some Actinomycetota (e.g. ''Streptomyces coelicolor''). The group is named after prodigiosin (prodiginine) and is biosynthesized through a common set of enzymes. They are interesting due to their history and their varied biological activity.

They are also found in Actinomycetes, for example ''Streptomyces coelicolor'' and some marine bacteria, including '' Hahella chejuensis'' and ''Pseudoalteromonas denitrificans''. Cyclononylprodigiosin was isolated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bloody Bread - Serratia Marcescens In Action
''Bloody'', as an adjective or adverb, is a commonly used expletive attributive in British English, Australian English, Irish English, Indian English and a number of other Commonwealth nations. It has been used as an intensive since at least the 1670s. Considered respectable until about 1750, it was heavily tabooed during c. 1750–1920, considered equivalent to heavily obscene or profane speech. Public use continued to be seen as controversial until the 1960s, but since then, the word has become a comparatively mild expletive or intensifier. In American English, the word is used almost exclusively in its literal sense and is seen by American audiences as a stereotypical marker of British English, without any significant obscene or profane connotation. Canadian English usage is similar to American English, but use as an expletive adverb may be considered slightly vulgar depending on the circumstances. Origin Use of the adjective ''bloody'' as a profane intensifier preda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
