This comprehensive review investigates the potential of cyanobacteria, particularly nitrogen-fixing strains, in addressing global challenges pertaining to plastic pollution and carbon emissions. By analyzing distinctive characteristics including their minimal growth requirements, high photosynthetic efficiency, rapid rates, this study elucidates crucial role transforming sequestration, biofuel generation, biodegradable production. The investigation emphasizes cyanobacteria’s efficiency photosynthesis, positioning them as optimal candidates for cost-effective bioplastic production with minimized land usage. Furthermore, explores unconventional yet promising utilization biodiesel production, mitigating environmental concerns such sulfur emissions presence aromatic hydrocarbons. resulting exhibits significant combustion potential, establishing cyanobacteria a viable option sustainable Through assessment both achievements encountered during commercialization process, offers valuable insights into diverse contributions cyanobacteria. Its objective is provide guidance researchers, policymakers, industries interested harnessing bio-inspired approaches structural applications, thereby advancing efforts towards environmentally conscious

The textile industry generates highly contaminated wastewater. It severely threatens local ecosystems without proper treatment, significantly diminishing biodiversity near the discharge point. With rapid growth rates, microalgae offer an effective solution to mitigate environmental impact of wastewater, and generated biomass can be valorised. This study sets out achieve two primary objectives: (i) assess removal pollutants by Chlorella vulgaris from distinct real wastewaters (without dilution) (ii) evaluate microalgal composition for further valorisation (in a circular economy approach). Microalgae grew successfully with rates ranging 0.234 ± 0.005 0.290 0.003 d−1 average productivities 78 3 112.39 0.07 mgDW L−1 d−1. All cultures demonstrated significant reduction in nutrient concentrations values below legal limits discharge, except COD effluent 2. Furthermore, pigment concentration culture increased during presenting advantage over conventional ones due economic value produced pigments. underscores promise wastewater treatment provides valuable insights into their role addressing challenges poses.

Despite of the possibility to include microalgae in civil wastewater treatment process, practice is still not common due lack available instruments implement it. In this study, a straightforward comprehensive approach for dealing with microalgal involving an original kinetic model proposed. A first set batch cultures native strain Chlorella was firstly carried out obtain parameters: maximum growth factor (μmax) and half-saturation constant (Ks), each limiting nutrient. Maximum values 0.0279 PO43−, 0.0319 h−1 NH4+, 0.0352 glucose, 0.0263 overall medium were found. Regarding Ks, 1.08 mg L−1, 27.70 1.34 found NH4+ glucose respectively, value 2.8 % total nutrients medium. These parameters used multi-substrate able predict continuous operation within laboratory scale raceway reactor. The removal capabilities addressed pollutant evaluated system at dilution rates 0.0025, 0.005, 0.01 0.015 h−1. This represents significant step towards addressing utilizing microalgae.

Microalgal technologies interact with other processes, enabling treatment systems to remove nutrients and pollutants while facilitating the reuse of final effluents. However, development these in various climates their specific characteristics has been poorly studied. The objective this work was evaluate influence different tropical seasons within Cerrado Biome on effluent a closed photobioreactor using consortium native microalgae. Cultivation performed bench scale anaerobically digested sanitary wastewater processed by two mechanisms from plant Bauru, Brazil: Upflow Anaerobic Filter (UAF) Baffled Reactor (ABR). cultivation took place an outdoor area constant aeration under natural climatic conditions during seasons: summer winter. Each season's occurred triplicate over 7 days. After cultivation, microalgal biomass were separated tannin-based organic coagulant (Tanfloc SG) quality for non-potable reuse. During summer, UAF achieved 76 ± 3 % 84 1.2 phosphorus nitrogen removal, respectively, ABR 83 4 85 respectively. In winter, 86 2 89 5 nitrogen, removed UAF, 68 6 93 ABR. removal generic bacteria exceeded 3.0 log most conditions, experiments showing absolute values E. coli below 100 CFU·100 ml⁻1, indicating that could be used unrestricted irrigation. technology can serve as tertiary countries climates, promoting reintegration water into production cycle, which aligns circular economy principles.
