产品描述

General description

Sodium carbonate is also termed as soda ash. Solvay process uses sodium chloride and limestone to produce sodium carbonate.[2]

Application

Sodium carbonate has been used as a component in BG11 liquid media for cyanobacterial growth[3] and in G625 growth medium for Anabaena flos-aquae.[4] It has also been used to impregnate mixed-cellulose ester (MCE) filter.[5]

Biochem/physiol Actions

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

缓冲剂组分,可用于除去外周膜蛋白。
