There are several of them, try gum acacia and LAB, you can use freeze drying or spay drying.

Thank you for your reference. Could you able to give an idea about the lifetime calculation of emulsified probiotics?

GUNA

There is no straight forward calculation. There will be loss during processing and storage, it will depend on encapsulation technology, encapsulation matrix, storage condition , the strain used etc......

Yeah. I understand. Do you know, how to inoculate bacterial culture into water column, like beads? I wish to introduce probionts into aquarium tanks with prebiotics, like starch, alginate.

there are many carrier and natural promising material that i think should be natural mainly if you will used for human consumption

Materials used for Microencapsulation • Various types of encapsulating materials are used for the process. • Namely: – Alginate – Gellan gum and xanthan gum – k-Carrageenan – Cellulose acetate phthalat – Chitosan – Starch – Pectin – Gelatin – Whey proteins – Chickpea protein

The assortment of any material depends on 1) its capsule forming capability, 2) its strength, 3) its enhancing viability of probiotics, 4) its cheapness, 5) its availability, 6) biocompatibility
