Project: Bio-treatment of sewage water and recovery  of eroded soils

Principal Researcher: Dr. Yoav Bashan Binjamin

The main objective of this project is to develop a new combined strategy for sewage water bio-treatment and eroded soil recovery using growth promoting bacteria in micro-algae (MGPB) and micro-algae trapped together in polymers (gelling substratum).

Specific Objectives:

  • Study different combinations of micro-algae and beneficial bacteria for micro-algal growth to find the best system for sewage water treatment.

  • Scaling up the sewage water bio-treatment system with organisms trapped in alginate spheres to bio-reagents of 5 liter capacity.

Electron micrography of plant growth promoting bacteria Azospirillum brasilense (Az) and the microalga Chlorella vulgaris (ch), sharing the same cavity (c) within an alginate sphere (Al). This combination is used for sewage water treatment.

Microalgae and bacteria co-immovilized in alginate spheres are cultured in a chemostat in semi-continuous systems.
