This study explored the potential of abundantly available sodium lignosulfonate (LS) as a reducer and fabricating agent in preparing silver nanoparticles (LS–Ag NPs). The operational conditions were optimized to make the synthesis process simpler, rapid, and eco-friendly. The prepared LS–Ag NPs were analyzed via UV–Vis spectroscopy, X-ray diffraction spectroscopy, Fourier transform infrared spectroscopy, and high-resolution transmission electron microscopy. Results demonstrated that LS–Ag NPs were of crystalline structure, capped with LS constituents, and spherical in shape with a size of approximately 20 nm. Under optimized conditions, LS–Ag NPs exhibited significant photocatalytic activity in Reactive Yellow 4G degradation. The effects of photocatalyst (LS–Ag NPs) dosage, dye concentration, and its reusability for dye degradation were studied to make the process practically applicable in textile wastewater treatment. Additionally, the synthesized LS–Ag NPs displayed significant free radical scavenging against 2-diphenyl-1-picrylhydrazyl (DPPH) with an IC50 value of (50.2 ± 0.70 µg/mL) and also exhibited antidiabetic activity in terms of inhibition in the activity of carbohydrate-degrading marker enzyme α-glucosidase with an IC50 value of (58.1 ± 0.65 µg/mL). LS–Ag NPs showed substantial antibacterial potential against pathogenic strains, namely E. coli and S. aureus. In conclusion, LS–Ag NPs can be a reliable and eco-friendly material for their possible application in the treatment of dye-containing wastewater and have a great perspective in the biomedical and pharmaceutical sectors.

“…Furthermore, cell wall enzymes reduce the metal ion to nanoparticles, and later, these nanoparticles spread across the bacterial cell wall. The extracellular generation of nanoparticles in the case of fungi is the nitrate reductase-mediated production in the presence of enzyme nitrate, which helps to bio-reduce metal ions into nanoparticles (Duygu et al 2019;Hulkoti and Taranath 2014). It provides a short description of recent PSM work involving in metallic nanoparticles synthesis.…”

Phosphorus (P) is one of the most important factors regarding plant growth and development. Its deficiency can be compensated by adding chemical fertilizers which are expensive and have an overall negative impact on the ecosystem. Their continuous use leads to the depletion of soil fertility, accumulation of toxic elements which will affect the normal soil micro flora, leading to an imbalance in equilibrium. Phosphate solubilizing microbes (PSM) may be an alternative way to overcome the P deficiency without causing any harm to environment. For this, their biodiversity, mode of action, colonizing ability and their careful relevance should be used as trustworthy components in sustainable agricultural systems. Due to variability in the performance of these microbes, their exploitation in the area of nanotechnology becomes a challenge in sustainable agriculture. In this review, we have discussed the use of PSM as biofertilizers, responsible factors and the strains that are used for the synthesis of different nanoparticles whose implementation will not only promote sustainable agriculture but also be helpful in commercial applicability.

“…To reduce microalgae biomass production costs, methods have been developed to utilize wastewater to culture strains with high sedimentation rates (Cheng et al, 2019;Leite and Daniel, 2020). Multicellular strains with high sedimentation rates, such as those belonging to the Pediastrum genus, were proposed for this application (DA LUZ et al, 2002); however, culturing Pediastrum requires more time than that required for unicellular strains with lower sedimentation rates and biomass productivity, such as members of the Chlorella genus (Duygu et al, 2019;Stone et al, 2019). In addition, while the sedimentation rates of multicellular strains are relatively high, it takes a long time to harvest the sedimented biomass (Su et al, 2012).…”

Bacterial and algal floc formation was induced by inoculating three species of wastewater-derived bacteria (Melaminivora jejuensis, Comamonas flocculans, and Escherichia coli) into algal cultures (Chlorella sorokiniana). Bacterial and algal flocs formed in algal cultures inoculated with M. jejuensis and C. flocculans, and these flocs showed higher sedimentation rates than pure algal culture. The floc formed by M. jejuensis (4988.46 ± 2589.81 μm) was 10-fold larger than the floc formed by C. flocculans (488.60 ± 226.22 μm), with a three-fold higher sedimentation rate (M. jejuensis, 91.08 ± 2.32% and C. flocculans, 32.55 ± 6.33%). Biomass and lipid productivity were improved with M. jejuensis inoculation [biomass, 102.25 ± 0.35 mg/(L·day) and 57.80 ± 0.20 mg/(L·day)] compared with the productivity obtained under pure algal culture conditions [biomass, 78.00 ± 3.89 mg/(L·day) and lipids, 42.26 ± 2.11 mg/(L·day)]. Furthermore, the fatty acid composition of the biomass produced under pure algal culture conditions was mainly composed of C16:0 (43.67%) and C18:2 (45.99%), whereas the fatty acid composition of the biomass produced by M. jejuensis was mainly C16:0 (31.80%), C16:1 (24.45%), C18:1 (20.23%), and C18:2 (16.11%). These results suggest the possibility of developing an efficient method for harvesting microalgae using M. jejuensis and provide information on how to improve biomass productivity using floc-forming bacteria.
