Fosse Way Fosse Way The Fosse Way was a Roman road in England that linked Exeter ("Isca Dumnoniorum") in South West England to Lincoln ("Lindum Colonia") in Lincolnshire, via Ilchester ("Lindinis"), Bath ("Aquae Sulis"), Cirencester ("Corinium") and Leicester ("Ratae Corieltauvorum"). It joined Akeman Street and Ermin Way at Cirencester, crossed Watling Street at "Venonis" (High Cross) south of Leicester, and joined Ermine Street at Lincoln. The word "Fosse" is derived from the Latin "fossa", meaning "ditch". For the first few decades after the Roman invasion of Britain in CE 43, the Fosse Way marked the western frontier of Roman rule in Iron
Aphanizomenon flos-aquae (dietary supplement) from the air, and water to synthesize proteins, carbohydrates, and lipids. AFA is also able to directly use molecular nitrogen from the air to produce proteins and other nitrogen-containing biomolecules. This ability is widespread in prokaryotes, but unknown in eukaryotes. "Aphanizomenon flos-aquae" as a species has both toxic and non-toxic forms. While benefits have been indicated, toxicity has been shown in some strains of the species "Aphanizomenon flos-aquae", with cylindrospermopsin and saxitoxins present, and microcystins found contaminating AFA dietary supplements. The World Health Organization's "Guidelines For Drinking Water Quality" note Anatoxin-a, saxitoxins, and cylindrospermopsins are present in the Aphanizomenon genus.
