一般描述

Hy-Case® SF是一种酪蛋白的高品质水解产物。酪蛋白含有丰富的氨基氮。经过强酸处理后，酪蛋白会发生水解，产生游离氨基酸和若干短肽片段。通过特殊处理将无机离子降到最低，因此Hy-Case® SF实际上是含盐量最少的高浓度游离氨基酸。它是一种精制级水解物，具有较高的溶液透明度。属于食品级，建议在需要高可溶性游离氨基酸混合物时使用。当无机离子水平需要保持在最低水平时，尤其推荐使用。

应用

建议用作需要高溶解性游离氨基酸混合物的实验室培养基、发酵和组织培养应用中的微生物营养物质。
酪蛋白水解产物 Hy-Case ® SF 用于 DMCY 培养基，在一项实验研究中研究了 ssgA 基因产物在促进灰色链霉菌产孢和细胞分裂中的作用。 它也可以在与脱氮盐杆菌 相关的研究中用于 YH 培养基，脱氮盐杆菌，被认为是一种碳水化合物利用、反硝化、极端嗜盐菌。

  5. How are the Amicase® (product A2427) and Hy-Case® SF (product C9386) different?

    The Amicase® (product A2427) and Hy-Case® SF (product C9386) are related items, but they are not exactly the same.  The Amicase® is prepared to keep the inorganic ions to a minimum so it is high in total nitrogen.  This is also the case for the Hy-Case® SF; however, this item is prepared to be essentially salt free (contains a maximum of 2.0% sodium chloride).  The Hy-Case® SF is recommended for use as a microbiological nutrient in laboratory media and fermentations, where a mixture of highly soluble free amino acids is required. It is especially recommended when inorganic ion levels need to be kept at a minimum.

Halobacterium denitrificans was one of several carbohydrate-utilizing, denitrifying, extremely halophilic bacteria isolated by anaerobic enrichment in the presence of nitrate. Anaerobic growth took place only when nitrate (or nitrite) was present and was accompanied by the production of dinitrogen.
