“…The methods of application range from seed coating application, root application, and foliar application, as well as incorporation directly into the soil to improve nutrient availability. Examples of microorganisms that promote plant growth include bacteria of the genera Rhizobium, Azospirillum, Bacillus, Streptomyces, Gluconoacetobacter, and Pseudomonas and filamentous mycorrhizal fungi such as Claroideoglomus, Glomus, and Rhizophagus, which are used in the production of bioinoculants [12][13][14]. Recently, there has also been an increase in studies on yeasts such as those of the genera Candida spp., Rhodotorula spp., Cryptococcus spp., and Saccharomyces sp., which have been reported to promote plant growth [15].…”

Agriculture plays a major role on society, especially in developing countries which rely on commodity exportation markets. To maintain high crop productivity, the use of agrochemicals was once employed as the main strategy, which in turn affected soil, water, and human health. In order to aid this issue, identifying some alternatives, such as the implementation of biofertilizers and inoculants as bioinputs in modern agriculture, are imperative to improve ecosystem quality. Among these bioinputs, a few bioproducts have shown good performances, such as phytohormones (e.g., auxins and giberellins), biosurfactants, and other enzymes; thus, it is extremely important to assure the quality and feasibility of their production in biorefinery scenarios. These bioproducts can be synthesized through fermentation processes through utilizing plant biomasses and agricultural byproducts as carbon sources. In this sense, to increase the tecno-economical availability of these processes, the implementation of solid-state fermentation (SSF) has shown great potential due to its ease of operation and cost-attractiveness. Therefore, this study aims to describe the main substrates used in SSF systems for the production of potential bioinputs; their associated operation hurdles, parameters, and conditions selection; the most suitable microorganisms; and the underlying mechanisms of these molecules in soil dynamics. Within this context, this study is expected to contribute to the development of new processes in modern biorefineries and to the mitigation of environmental impacts.

“…Advances in modern techniques have enabled us to investigate multiple AMF domains, such as physiology, function, and community associations of mycorrhizal fungi [11]. Worldwide, a diverse array of businesses, spanning from small to large enterprises and start-ups, actively participate in the production and distribution of AMF formulations or consortia products that encompass advantageous soil bacteria [12]. Over the past few decades, a substantial number of patents, exceeding 40 in total, have been generated, specifically pertaining to AMF.…”

Finding environmentally friendly solutions for crop growth and productivity has been gaining more attention recently. This meta-analysis aims to understand the combined application of arbuscular mycorrhizal fungi (AMF) and hydroponic systems compared to AMF in conventional (soil) systems. The analysis of up-to-date studies revealed that the root colonization, calculated as the proportion of colonized root segments relative to the total root length, by AMF in conventional (soil-based) culture exceeded hydroponic (or soilless) culture systems by 16.8%. The mean root colonization by AMF was determined to be 52.3% in hydroponic systems and 61.1% in conventional systems. Within hydroponic systems, the root colonization ranged from 2% to 20% after 10 days of inoculation, and notably, it exceeded 50% after 30 to 65 days, depending on the growing substrate and species. Under hydroponics, AMF application had a higher (compared to none-inoculated) positive effect on crop biomass and yield than fruit and leaf quality (antioxidants, phenols, and sugars) as well as leaf nutrients. However, AMF do not always have the potential to improve crop growth, quality and productivity in hydroponics. Among the studies analyzed in this review, approximately 34% (no effect: 29%; negative: 5%) reported no discernible positive effect on biomass or yield, 37% (no effect: 16%; negative: 21%) on fruit or leaf quality, and 60% (no effect: 47%; negative: 13%) on nutrient levels within plant tissues. To improve the performance of AMF in hydroponic systems, the meta-analysis recommended maintaining phosphorus levels in the nutrient solution within the range of 0.15 to 15.5 mg L−1 as elevated levels (40–75 mg L−1) were found to significantly reduce AMF colonization. Additionally, it was observed that certain hydroponic techniques, such as the presence of air bubbles generated by air pumps in floating hydroponic systems (Deep Flow technique) and continuous circulation of the nutrient solution (Ebb and Flow systems), may create dynamic conditions that could potentially hinder the introduction of AMF spores into hydroponic systems and potentially compromise the integrity of the spores and hyphae.

“…Furthermore, AMF positively affect plant tolerance to different abiotic and biotic stresses (Marro et al, 2022;Veresoglou and Rillig, 2012). These results have promoted the application in agriculture of AM fungal inoculants, and increasing numbers of commercial inoculants have been registered as amendments or biostimulants, and released onto the market in the last few decades (Benami et al, 2020;Sudheer et al, 2023).…”
