Production and Biotransformation of Phytosterol Microdispersions to Produce 4-Androstene-3,17-Dionent technologies. However, the initial concentration of phytosterols in batch cultures is limited due to its low solubility in aqueous media, causing serious difficulties for scaling up because of the low mass transfer. In this chapter, we describe a fermentation method of a phytosterol microdispersiExposure 发表于 2025-3-23 16:25:45

These plates, due to the standard footprint, can be integrated with liquid-handling systems and associated equipment expanding considerably their application and use. However, care has to be垫子 发表于 2025-3-23 21:53:10

Scale-Up of Phytosterols Bioconversion into Androstenedione,nto steroid intermediates by removing the C17 side chain. This chapter shows the scale-up, from flask to fermentor, of the phytosterols bioconversion into 4-androstene-3,17-dione (androstenedione; AD) with . B-3805. Due to the fact that phytosterols and AD are nearly insoluble in water, two-phase sy商品 发表于 2025-3-24 06:18:40

Process for Biotransformation of Androsta-4-ene-3, 17-Dione (4-AD) to Androsta-1,4-Diene-3,17-Dioneone, estradiol, estriol and other related derivatives. De novo synthesis of this molecule is not yet reported in any form of living system, i.e., microbial, plant, and animal. The structural complexities due to presence of several chiral carbon centers create significant hurdles in chemical synthesi蜈蚣 发表于 2025-3-24 12:17:54

,Obtaining of 11α-Hydroxyandrost-4-ene-3,17-dione from Natural Sterols,or obtaining 11α-hydroxyandrost-4-ene-3,17-dione (11α-HAD) from cheap and available natural sterols (phytosterols or cholesterol)..11α-HAD is a primary adrenal steroid in mammals and also a key precursor in the syntheses of halogenated corticoids. Conventional routes for its obtaining are based on coutrage 发表于 2025-3-24 21:41:43
