“…The treatment with AMF showed photosynthetic pigment contents in lettuce leaves similar to the control. In our study, although the application of AMF did not show a positive effect on the pigment contents, some previous studies indicated that AMF induces accumulation of those pigments in some leafy vegetables such as lettuce (Baslam et al 2011) and spinach (Khalid et al 2017).…”

Two pots experiments were conducted, during two successive winter seasons of 2016/2017 and 2017/2018, to test the role of biofertilizer inoculations (arbuscular mycorrhizal fungi, AMF; Bacillus megaterium, B. megaterium; and their mixture) in improving growth and quality of lettuce (Lactuca sativa L. cv. Balady) under different levels (0, 100, 200 and 300 ppm) of lead (Pb). The results illustrated that the growth and quality of lettuce were greatly affected by the escalated levels of Pb in soil. Clearly, the increased levels of Pb decreased plant growth parameters, the contents of macronutrient and micronutrient as well as photosynthetic pigments, but increased the contents of Pb in the different parts of lettuce plants. Among the tested biofertilizer inoculations, the combined inoculation (AMF + B. megaterium) showed superior effects for increasing plant growth, contents of nutrient and photosynthetic pigments. AMF and the combined inoculation treatment exhibited an equal efficiency for reducing the content of Pb in the old and new leaves (edible parts) of lettuce plants, while B. megaterium showed the best performance in reducing the content of Pb in lettuce roots. Our study suggested that the combined inoculation (AMF + B. megaterium) is an effective tool for improving growth and quality of lettuce in high-contaminated soil with Pb.

“…Substantial contribution of Biofertilizer in sustainable maintenance of human health has been reported. Biofertilizers improve the nutritious properties of fresh vegetables by increasing; the antioxidant activity, the total phenolic compounds and chlorophyll ( Khalid et al, 2017 ). Spinach inoculated with different biofertilizers was found to have 58.72 and 51.43% higher total phenolic content than the un-inoculated control ( Khalid et al, 2017 ).…”

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.

Biofortification has been used to improve micronutrient contents in crops for human consumption. In under-developed regions, it is important to fortify crops so that people can obtain essential micronutrients despite the limited variety in their diets. In wealthy societies, fortified crops are regarded as a “greener” choice for health supplements. Biofortification is also used in crops to boost the contents of other non-essential secondary metabolites which are considered beneficial to human health. Breeding of elite germplasms and metabolic engineering are common approaches to fortifying crops. However, the time required for breeding and the acceptance of genetically modified crops by the public have presented significant hurdles. As an alternative approach, microbe-mediated biofortification has not received the attention it deserves, despite having great potential. It has been reported that the inoculation of soil or crops with rhizospheric or endophytic microbes, respectively, can enhance the micronutrient contents in various plant tissues including roots, leaves and fruits. In this review, we highlight the applications of microbes as a sustainable and cost-effective alternative for biofortification by improving the mineral, vitamin, and beneficial secondary metabolite contents in crops through naturally occurring processes. In addition, the complex plant–microbe interactions involved in biofortification are also addressed.
