Producing large beads from alginate. Principle and equipment. Principle. Alginate solution + divalent cations (Ca, Ba, etc.) = solidified matrix (gel-like material). If alginate solution is forced into a droplet shape, the result will be a solid bead (sphere).

Producing large beads from alginate
Principle and equipment
Alginate solution +divalent cations
(Ca, Ba, etc.)=solidified matrix(gel-like material)
If alginate solution is forced into a
droplet shape, the result will be a
solid bead (sphere)
…If all you need are a few grams of beads for your experiments…
The method just shown is ideal and you need not read further.
…If your experiment requires large quantities of beads (one or more liters)…
You will find the syringe method very tiresome, especially when hard beads are needed when employing highly viscous alginate solutions
Some equipment is needed
Microorganisms entrapped in alginate are
often grown in large fermentation vats,
similar to the vat pictured at left.
The products they produce are harvested,
while the beads remain inside the vat.
Something for the future--
Large-scale treatment by
immobilized and co-
The sky is the limit…
Use your imagination
