“…It was observed that experimental plants co-inoculated with G. fasciculatum and G. mosseae showed the highest content of flavonoids in T5 and T6, which were 48.02 and 40.46% greater than that of control plants. Investigation of antioxidant biosynthesis and induction of phytochemicals including flavonoids by AMF has earlier been documented in several reports (Carlsen et al 2008 ; Eftekhari et al 2012 ; Nisha and RajeshKumar 2010 ). Similarly, phenolic acids were also recorded to be significantly higher in all treatments compared with control.…”

BackgroundThis study evaluates the influences of bio fertilizers containing mycorrhizal fungi (Glomus fasciculatum, Glomus mosseae) individually or in combination with N-fixer (Azotobacter chroococcum), K solubilizer (Bacillus mucilaginous) and P solubilizer (Bacillus megaterium) on soil fertility and phytochemical levels of spinach.ResultsRoot colonization by mycorrhizal fungi was increased in the presence of bacterial inoculation in comparison to individual inoculation treatments. Inoculation of bio fertilizer containing mycorrhizal fungi and bacterial species considerably augmented the concentration of total phenolic compounds, flavonoids and phenolic acid contents. The 1, 1-diphenyl-2-picrylhydrazyl (DPPH) scavenging capacity of spinach was found to be positively coincided with flavonoid contents, while partially correlated with total phenolic compounds and phenolic acids. Further, the HPLC analysis showed that significantly higher antioxidant activity of spinach was correlated with quercetin contents and chlorogenic acid. Chlorophyll contents were also increased following the bio fertilization treatments.ConclusionResults revealed that these microbes are useful tool for improving health promoting compounds in spinach.

Taxonomic resolution is a determinant of biodiversity effects in arbuscular mycorrhizal fungal communities

et al. 2016

Summary1. Arbuscular mycorrhizal fungi (AMF) are key regulators of ecosystem processes, yet how their biodiversity works in ecosystems remains poorly understood. 2. We documented the extent to which taxonomic resolution influenced the effect of biodiversity of AMF taxa on plant performance (growth, nutrient uptake and stress tolerance) in a meta-analysis of 902 articles. 3. We found that the effect of biodiversity of AMF taxa depended on taxonomic resolution. Plant performance was positively promoted by AMF family richness, while no effect was found for fungal species richness. In addition, negative effect was found between AMF phylogenetic diversity and plant growth. This pattern can be explained by functional conservatism within AMF families and functional differentiation among AMF families. 4. Synthesis. Conservation of AMF communities to maintain a full complement of ecosystem functions requires the presence of diverse families and not simply diverse species within a family. This finding may be of key importance for the function of ecosystems under various environmental perturbations to which AMF families may respond differently.

“…Higher (48.02 and 40.46%) flavonoid content (antioxidant) was observed in lettuce co-inoculated with G. fasciculatum and Glomus mosseae ( Baslam et al, 2011 ). Antioxidant biosynthesis by Arbuscular Mycorrhizal Fungi (AMF) has been reported ( Carlsen et al, 2008 ; Nisha and RajeshKumar, 2010 ; Eftekhari et al, 2012 ). Taie et al (2008) , documented a 75% increase of phenolic acid biosynthesis in soybean seedlings inoculated with Rhizobacteria.…”

Microbial Inoculants for Improving Crop Quality and Human Health in Africa

Current agricultural practices depend heavily on chemical inputs (such as fertilizers, pesticides, herbicides, etc.) which, all things being equal cause a deleterious effect on the nutritional value of farm product and health of farm workers and consumers. Excessive and indiscriminate use of these chemicals have resulted in food contamination, weed and disease resistance and negative environmental outcomes which together have a significant impact on human health. Application of these chemical inputs promotes the accumulation of toxic compounds in soils. Chemical compounds are absorbed by most crops from soil. Several synthetic fertilizers contain acid radicals, such as hydrochloride and sulfuric radicals, and hence increase the soil acidity and adversely affect soil and plant health. Highly recalcitrant compounds can also be absorbed by some plants. Continuous consumption of such crops can lead to systematic disorders in humans. Quite a number of pesticides and herbicides have carcinogenicity potential. The increasing awareness of health challenges as a result of consumption of poor quality crops has led to a quest for new and improved technologies of improving both the quantity and quality of crop without jeopardizing human health. A reliable alternative to the use of chemical inputs is microbial inoculants that can act as biofertilizers, bioherbicide, biopesticides, and biocontrol agents. Microorganisms are able to carry out the plant growth promotion, pest and disease and weed control. Microbial inoculants are beneficiary microorganisms applied to either the soil or the plant in order to improve productivity and crop health. Microbial inoculants are natural-based products being widely used to control pests and improve the quality of the soil and crop, and hence human health. Microbial inoculants involve a blend of microorganisms that work with the soil and the soil life to improve soil fertility and health and by extension improve human health. Microbial inoculants have the ability to minimize the negative impact of chemical input and consequently increase the quantity and quality of farm produce. Microbial inoculants are environmental-friendly and deliver plant nutrients to plants in a more sustainable manner. Microbial inoculants can help reduce chemical fertilizer application. Microbial inoculants could include bacteria, fungi and algae. This research summarizes the impact of agricultural chemical inputs on human health. The contribution of microbial inoculants in sustainable maintenance of human health will be expatiated. Advances in microbial inoculants and technology and strategies to explore this natural, user friendly biological resource for sustainable maintenance of plant health will be discussed.
