“…Future research should explore the cost-effectiveness of producing and using different concentrations of A. maxima-sonicated biomass for promoting plant growth and yield in basil, to determine an optimal concentration based on the effects on growth and economic feasibility. Moreover, it is worth investigating whether ultrasonication is a necessary step in the production, as drying biomass is an effective cell-lysing method [49]. Recent research suggests that ultrasonication may be redundant for cell lysis when sun-drying is also part of the protocol (unpublished).…”

The continued increase in human populations and use of chemical fertilizers remain a threat to the health and stability of human–ecological systems worldwide. To ameliorate this problem and achieve long-term food security, a variety of ecofriendly technologies have been developed, including the production of cyanobacteria-based biofertilizers. This technology can be optimized through experiments that assess how plant growth is enhanced under different biofertilizer concentrations (g L−1). In this study, the biofertilizer capabilities of various concentrations of sonicated biomass (0, 2.5, 5, 10, 20, and 40 g L−1) derived from the cyanobacteria Arthrospira maxima on the growth of basil (Ocimum basilicum, Lamiaceae) were assessed, comparing their effectiveness with that of a positive control, a commercial biofertilizer (OptiMar Algas Marinas®) administered at 4 mL L−1. Generally, increased concentrations led to enhanced growth parameters; however, discernible differences from the negative control (0 g L−1) were often observed only when concentrations exceeded 5 g L−1. Surprisingly, the negative and positive controls often yielded similar results. A chemical composition analysis of A. maxima revealed high concentrations of the phytohormones, macronutrients, and essential amino acids that likely explain how our A. maxima sample enhanced growth in basil. Further research is required to determine how other crop plants respond to different concentrations of A. maxima. Additionally, assessing the feasibility of creating an economically accessible product with a higher concentration of A. maxima is crucial for practical applications.

Continued increase of human populations and use of chemical fertilizers remain a threat to the health and stability of human-ecological systems worldwide. To ameliorate this problem and achieve sustainable agriculture, a variety of ecofriendly technologies have been developed, including the production of cyanobacteria-based biofertilizers. This technology can be optimized through experiments that assess how plant growth is enhanced under different biofertilizer concentrations (g L− 1). Here we assess the biofertilizer potential of hydrolysates derived from the cyanobacteria Arthospira maxima on the growth of basil (Ocimum basilicum) under six different concentrations (0, 2.5, 5, 10, 20, and 40 g L− 1), and an additional treatment where we applied the registered product Optimar ® (4 mL L− 1). For all response variables except stem length, a concentration of 40 g L− 1 yielded significantly higher values. The beneficial effects of the application of Optimar were often surpassed when plants received cyanobacteria concentrations above 10 g L− 1. A chemical composition analysis of A. maxima revealed high concentrations of the phytohormones gibberellic acid (0.19 g L− 1), 6-benzyladenine (0.37 g L− 1), and 1-naphthaleneacetic acid (0.25 g L− 1) that are likely responsible for the cyanobacteria’s biostimulant activity. Further research is required to determine how other crop plants respond to different concentrations of A. maxima and the viability of creating an economically accessible product with a higher concentration of A. maxima using circular economy and biorefinery concepts to obtain high value-added by-products.
