We have been interested in immobilizing different adsorbents such as activated carbon powder and ion-exchange resins in hydrogels such as calcium alginate or potassium carrageenan. The... [Pg.128]

The immobilized XAD-4 resins in E-carrageenan and calcium alginate are non-toxic to the microbial culture. Thus, the adsorbents can be added directly to the fermenting broth. Both fermentation and product separation can occur at the same time (8). As shown in Table 1, the immobilized resin can be recovered from the fermentation broth. The cycloheximide product can be recovered from the immobilized beads by extraction using butyl acetate. The immobilized beads maintained its mechanical strength through the extraction. In some cases, the purity of the cycloheximide in the solvent is close to 95-100% pure. Very limited additional purification such as crystallization may be used to make the final pure product. [Pg.134]

Transformations with immobilized enzymes or cells Often the stability of the biocatalyst can be increased by immobilization and many different enzymes and cells have been immobilized by a variety of different methods. The most popular method for the fixation of whole cells is entrapment or encapsulation with calcium alginate. Other natural gels e.g., carrageenan, collagen, chemically-modified natural polymers e.g., cellulose acetate and synthetic gels and polymers e.g., polyacrylamide or polyhydroxyethylmethacrylate can also be used for this type of immobilization. [Pg.847]

Calcium alginate [345-347] as well as K-carrageenan [348-350] has been used for immobilizing baker s yeast, and a sodium alginate/calcium chloride-immobilized baker s yeast has been used during the synthesis of d- and L-armentomycin [351]. This system has also been used for tiie reduction of several p-keto esters [352], and the antiselectivity as well as the yields was improved compared to reductions using classical conditions [217,353-355]. Calcium alginate-immobilized cells of S. cerevisiae were pretreated at 50 °C for 30 min, and tiien the cells showed an increased performance (80%) and an excellent selectivity (ee 99%) in the reduction of 3-chloropropiophenone... [Pg.530]

In addition, whereas the bioreduction of the keto acid 73 (Fig. 20) with immobilized BY entrapped in carrageenan beads did not have satisfactory results, use of BY entrapped in calcium alginate gave 74 in 40% yield and with an e.e. of 95% [101]. Several a-ketols have been reduced by BY and gave the corresponding diols [102-104] or lactones [105]. [Pg.535]

As with carrageenan, another seaweed extract, the ability to bind to calcium makes alginates useful in dairy products as a thickener. It also makes alginates useful as wound dressings, where they absorb fluids, and stop bleeding, and act as a scaffold. [Pg.143]
