Adsorption is just the first part of our journey. We took metals from wastewater and now we want to release it from biomass and use/deposit further? But how?
Team in BioBureau is working on it. We are trying different approaches to release bacteria from biomass: to be effective, economically favorable, and to try to keep bacteria alive.
So far we gave chance to 1M HCl, 1mM EDTA, andCO2.
At this moment, the results show that HCl releases more metal ions from biomass, but kills bacteria. In the future research we should try to optimize process. Plan is to take even more metal from bacteria, while preserving bacteria, so that biomass can be used again.
