Romano-Celtic temple purpose within the ritual environment of the temple. The temple at Woodeaton produced evidence for multiple hearths within the temple superstructure, suggesting the use of fire within the religious worship at that site. A priest would perform religious ceremonies within the temple or outside in the enclosure, although the exact daily role they played in Romano-Celtic temples is not well understood. Performing sacrifice, prayers, and overseeing festivals are key features of priesthoods in the Roman Empire. In Aquae Sulis (modern Bath, England), an altar was dedicated by a "haruspex"; this religious position may have been utilised elsewhere in Britannia. Fragments
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.
