Highlights
- Tannery wastewater is rich in organic and inorganic components which act as nutrient source for cyanobacteria and microalgae.
- Constructed simple photobioreactor is used for cultivating cyanobacteria and microalgae using tannery wastewater.
- Cultivated biomass of cyanobacteria and microalgae are rich in nitrogen and phosphorus.
- The biomass of cyanobacteria and microalgae used as liquid biofertilizers to analyze and enhance the germination indices of Vigna radiata.
Abstract: Tannery wastewater serves as a nutritional source for cyanobacteria and microalgae to grow and accumulate nutrients, which could be further utilized for the production of value-added products. Various nutrients present in wastewaters support microalgae for the accumulation of biomass that consists of various fertilizer components (nitrogen, phosphorus, and potassium). The gold liquid of wastewater and microalgae/cyanobacteria may be severe in various ways. This research is focused on the concept of liquid biofertilizers. In this study, the secondary treated tannery wastewater (STTWW) was used as a nutrient source to grow cyanobacteria Planktothrix agardhii NIVA-CYA (OR287155) and microalgae Chlorella sorokiniana NMLX (OR287445) and then the cyanobacteria and microalgae containing STTWW was used as liquid biofertilizer on Vigna radiata L seeds. The results revealed that cyanobacteria-incorporated STTWW increased root growth (76.8%) at 80% dilution while microalgae-incorporated STTWW promoted drastic shoot growth with an increase of 88% at 100% dilution. Also, all the seeds were able to germinate at 100% cyanobacteria and microalgae containing STTWW. Overall, connecting liquid cyanobacterial/microalgal biofertilizers to seed growth can be a valuable research field to demonstrate how sustainable and nutrient-rich alternatives can positively impact plant growth and contribute to sustainable agriculture practices.
