설명

일반 설명

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

애플리케이션

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.

생화학적/생리학적 작용

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

Buffer component, may be used for the removal of peripheral membrane proteins.

기타 정보

Salt component in the fractionation of multivalent nucleotides by inorganic salt co-precipitation
