Anaerobic respiration can be investigated in yeast immobilised in alginate balls. These notes outline the procedure. Once you have mastered the technique you can explore your own questions about respiration in yeast, such as the effects of temperature, different sugars or conduct a search for inhibitors. Materials 1.5% sodium alginate solution

Immobilised yeast Additional investigations Ordinary bakers’ yeast, Saccharomyces cerevisiae, is unable to ferment the sugar lactose. The enzyme b-galactosidase breaks down lactose to glucose and galactose. Yeast that is co-immobilised with this enzyme is able to grow in a medium that contains lactose. Of the two sugars formed by enzyme

2012年1月1日 · Yeast Saccharomyces cerevisiae was immobilized using 3% (w/v) of sodium alginate and 2% (w/v) calcium chloride using entrapment technique, in the form of beads.

2019年3月2日 · An enzyme is usually immobilized onto an inert, insoluble material e.g. Calcium alginate. This is produced by the reaction of a mixture of Sodium alginate solution with Calcium chloride. These beads provide increased resistance to …

1986年3月1日 · A method for immobilizing yeast cells in alginate particles by internal gelation was investigated. The alginate is gelled in situ by the liberation of Ca ions from insoluble calcium compounds through the pH lowering which accompanies d-glucono-1,5-lactone hydrolysis in the presence of solution. With the internal gelation method gel particles of ...

Yeast protoplasts may regenerate the cell wall and revert to cells if immobilized in a 2%–5% Ca-alginate gel and cultured in an osmotically stabilized medium. The method of protoplast immobilization and subsequent isolation from the gel is described in detail.

2019年5月28日 · Alginate-chitosan (AC) microcapsules were prepared as immobilization carriers by emulsification-internal gelation and complexation reaction, and their contribution on facilitating the growth and metabolism of yeast cells were testified successfully in culture medium-solvent biphasic systems.
