Beschreibung

Allgemeine Beschreibung

Sodium carbonate is also termed as soda ash. Solvay process uses sodium chloride and limestone to produce sodium carbonate.

Anwendung

Sodium carbonate has been used as a component in BG11 liquid media for cyanobacterial growth and in G625 growth medium for Anabaena flos-aquae. It has also been used to impregnate mixed-cellulose ester (MCE) filter.

Biochem./physiol. Wirkung

Pufferbestandteil, kann zur Entfernung peripherer Membranproteine eingesetzt werden.

Sodium carbonate helps to improve the pretreatment of rice straw and develops delignification process.

Sonstige Hinweise
