一般說明

聚乳糖酸钠能隔离金属离子,在真菌培养中,它被用作多聚半乳糖醛酸酶的碳源和诱导剂。

應用

钠盐可以用来隔离金属离子。在真菌培养中,它被用作多聚半乳糖醛酸酶的碳源和诱导剂。多聚半乳糖醛酸已被用于研究评估来自链霉菌属的一种碱活性和碱稳定的果胶酸裂解酶。S27 在纺织工业中具有潜力。 还应用于黄鼠多聚半乳糖醛酸酶合成条件的优化研究。

生化/生理作用

在陆生植物中,多聚半乳糖醛酸是细胞壁多糖(果胶)的主要成分。结合多聚半乳糖醛酸酶抑制肽 (PGIP) 保护果胶免受真菌多聚半乳糖醛酸酶的降解。

The effects of glucose and of a pectic substrate in the duplication cycle, spore polarization and septation of Aspergillus nidulans were tested in poor and rich media. Growth on poor conditions and on sodium polypectate slowed nuclear duplication and reduced

A pectate lyase (PL1) from the tomato vascular wilt pathogen Fusarium oxysporum f.sp. lycopersici was previously characterized, and evidence was obtained for its production in planta. The gene encoding PL1 was isolated from a genomic library of F. oxysporum f.

Penicillium frequentans synthesized eleven polygalacturonases and three pectinesterases when grown in the presence of pectin, sodium polypectate or monogalacturonic acid. When glucose was the sole carbohydrate source in the medium two of these polygalacturonases and one pectinesterase were produced. The
