“…Repeated use of chemical fertilizers and pesticides that are rich in nitrogen, phosphorous, and potassium lead to soil, air, and groundwater pollution [ 220 ]. Interestingly, the use of PGPB is a potent and upcoming method to ensure sustainable agriculture without depleting natural resources [ 221 , 222 ]. The introduction of successful PGPB to soil ecosystems improves soil’s physical (e.g., reducing sodicity and bulk density, improving water infiltration rate, and increasing porosity and aeration) and chemical (e.g., reducing acidity) properties [ 223 ].…”

As a major food crop, rice (Oryza sativa) is produced and consumed by nearly 90% of the population in Asia with less than 9% produced outside Asia. Hence, reports on large scale grain losses were alarming and resulted in a heightened awareness on the importance of rice plants’ health and increased interest against phytopathogens in rice. To serve this interest, this review will provide a summary on bacterial rice pathogens, which can potentially be controlled by plant growth-promoting bacteria (PGPB). Additionally, this review highlights PGPB-mediated functional traits, including biocontrol of bacterial rice pathogens and enhancement of rice plant’s growth. Currently, a plethora of recent studies address the use of PGPB to combat bacterial rice pathogens in an attempt to replace existing methods of chemical fertilizers and pesticides that often lead to environmental pollutions. As a tool to combat bacterial rice pathogens, PGPB presented itself as a promising alternative in improving rice plants’ health and simultaneously controlling bacterial rice pathogens in vitro and in the field/greenhouse studies. PGPB, such as Bacillus, Pseudomonas, Enterobacter, Streptomyces, are now very well-known. Applications of PGPB as bioformulations are found to be effective in improving rice productivity and provide an eco-friendly alternative to agroecosystems.

“…However, this variation in plant height was only true in the ORG system when spraying was modified by the interaction with the system in Y1 (Table 4). Possibly, biofertilizer sprays have a positive effect on plant growth by increasing the absorption of relatively immobile nutrients including P, Zn and Cu from the soil, making them more readily accessible to plants, which promotes sprouting and shoot elongation [41]. In addition, at different stages of plant growth, different mineralization rates and nutrient availability can explain the variable levels of nutrients in the soil amendment [42].…”

A two-year study (harvest years 2019 and 2020) was conducted to investigate the effect of a commercially available biofertilizer, in combination with variable nitrogen (N) rate, on bread baking quality and agronomic traits in hard winter wheat grown in conventional (CONV) and organic (ORG) farming systems in Kentucky, USA. The hard red winter wheat cultivar ‘Vision 45’ was used with three N rates (44, 89.6 and 134.5 kg/ha as Low, Med and High, respectively) and three biofertilizer spray regimes (no spray, one spray and two sprays). All traits measured were significantly affected by the agricultural production system (CONV or ORG) and N rate, although trends in their interactions were inconsistent between years. In Y2, yield was greatest in treatments with high N rates and in the ORG system. Biofertilizer treatments had a negative to neutral effect on grain yield. Baking quality traits such as protein content, lactic acid solvent retention capacity and sedimentation value (SV) were consistently greater in the CONV system and increased with the higher N application rates. Similarly, biofertilizer application had no effect on predictive baking quality traits, except for SV in year 1 of the study, where it increased with two sprays. Loaf volume was consistently greater from wheat grown in CONV treatments. From these results, we conclude that further research is warranted to evaluate the potential for biofertilizers to enhance N uptake and affect bread baking quality or other end-use traits. Additional research may be especially useful in organic production systems where biologically based N fertilizers are utilized, and treatments were not negatively affected by biofertilizer applications. Such strategies may be needed to increase protein quantity and gluten quality to optimize winter wheat production for bread baking qualities in the southeastern USA.

“…However, there are some drawbacks to microalgae cultivation for biofertilizers. These drawbacks include the unpredictability of algae feedstock supply, regional and seasonal availability, and local energy supply; high production costs for cultivation, harvesting, transporting, storing, and pre-treating; variability in quality, low farmer awareness and assurance (Patra & Singh, 2019); and high initial capital investment. However, using wastewater and removing pollutants and nutrients is a win-win process that is more affordable and environmentally sustainable.…”

Microalgae are microscopic organisms that have a broad range of applications, from wastewater treatment, CO 2 mitigation to therapeutic proteins, and pharmaceuticals. Recently, the combination of wastewater treatment-based microalgae and the use of the obtained biomass as biofertilizers/stimulants/pesticides have been highly emphasized for their use in the agriculture field. Biofertilizers are a need of today's agriculture practices due to the increasing demand for food to feed a hungry planet while avoiding chemical contamination by the over-application of synthetic fertilizers. There is a constant need for modern techniques for the use of microalgae in a sustainable manner to harness their products to their full extent. Various types of bioreactors are available on the market, each with its own advantages and disadvantages, which, based on their efficiency, can be used for microalgae cultivation. This review aims at reporting recent developments in microalgae biotechnology, especially related to CO 2 mitigation, wastewater purification, biofuel, feedstock, future food, therapeutic proteins, pharmaceuticals, and biofertilizers, highlighting some of the current research in this field and future development priorities.
