چکیده
Cultivation of photosynthetic microorganisms in wastewater is a potential cost-effective method treating and simultaneously providing the essential nutrients for high-value biomass production. This study investigates cultivation cyanobacterium Arthrospira platensis non-diluted non-pretreated brewery under non-sterile alkaline growth conditions. The system’s performance terms productivity, pollutant consumption, pigment production composition was evaluated different media formulations (i.e., addition sodium chloride and/or bicarbonate) irradiation conditions continuous illumination 16:8 light:dark photoperiod). It observed that combination bicarbonate with resulted maximum recorded at end experiments, use photoperiod led to increased removal (up 90% initial concentrations) concentration (950 mg/L). microbial communities established during experiments also determined. heterotrophic bacteria dominated by phyla Pseudomonadota, Bacillota, Bacteroidota prevailed, while cyanobacteria population showcased dynamic behavior throughout as it towards (relative abundance 10% 30% application, respectively). Overall, platensis-based proved be an effective treatment, although large numbers limit usage produced applications such biofuel biofertilizer

In this study, zeolite was employed for the separation and recovery of P from synthetic wastewater and its use as phosphorus (P) source for the cultivation of the green microalga Chlorella vulgaris and the cyanobacterium Arthrospira (Spirulina) platensis. At P-loaded zeolite concentration of 0.15-1 g/L, in which P was limited, the two species displayed quite different behavior regarding their g...

The genus Arthrospira comprises a group of filamentous multicellular cyanobacteria and can be used for animal feed and human food. Solid state fermentation or cultivation (SSF) involves the use of a culture medium composed of solid material with given moisture content. No studies have been published about the cultivation of microalgae or cyanobacteria on solid medium. Furthermore, although suga...
