The ability of selected bacteria: Myxococcus xanthus , Bacillus pumilus , Halobacterium salinarum , and Brevibacterium antiquum to produce phosphorus bio‐mineral in settled wastewater and sludge dewatering centrifuge liquors was investigated. B. pumilus and B. antiquum were capable of growing and producing bio‐minerals identified as struvite that reached up to 250 µm in size within ten days. This study opens a completely new route to remove and recover phosphorus as struvite from wastewater, with advantages such as being able to use streams with variable phosphorus concentrations of (7–30 mg/L) and no need for external chemicals.
