“…Microbes can be manipulated and used as food sources and nutrient providers for humans and livestock. Microbes can produce carbohydrates, lipids, proteins, minerals, and vitamins (Wang et al, 2021 ; Akkaya and Can-Guven, 2022 ; Kurniawan et al, 2022 ). Proteins are essential in human diets and animal feed formulations (Silva et al, 2022 ; Pyne et al, 2022 ).…”

“…Nanoparticle-based fertilizers (NPF) offer an advantage over bulk or conventional fertilizers due to their easy absorption and transportation in plant vascular tissues. They can also be used as carriers for fertilizers and pesticides, which can enhance chemical efficiency and reduce operational costs (Rastogi et al, 2017 , 2019 ; Ng et al, 2021 ; Noor-Hashim et al, 2021 ). The technique of using microbial enzymes (bacterial or fungal) in the production of NPs is referred to as “green synthesis of nanoparticles” (Zielonka et al, 2018 ).…”

“…Silica nanoparticles (Si-NP) are an example of fertilizers that are successfully produced using Aspergillus parasiticus (Zielonka et al, 2018 ) or Trichoderma (review by Ramirez-Valdespino and Orrantia-Borunda, 2021 ). Additionally, the use of silicon has been reported to enhance the growth and productivity of rice, which is one of the main staple food crops (Zielonka et al, 2018 ; Ng et al, 2021 ; Noor-Hassim et al, 2021 ).…”

As the global human population continues to grow, the demand for food rises accordingly. Unfortunately, anthropogenic activities, climate change, and the release of gases from the utilization of synthetic fertilizers and pesticides are causing detrimental effects on sustainable food production and agroecosystems. Despite these challenges, there remain underutilized opportunities for sustainable food production. This review discusses the advantages and benefits of utilizing microbes in food production. Microbes can be used as alternative food sources to directly supply nutrients for both humans and livestock. Additionally, microbes offer higher flexibility and diversity in facilitating crop productivity and agri-food production. Microbes function as natural nitrogen fixators, mineral solubilizers, nano-mineral synthesizers, and plant growth regulator inducers, all of which promote plant growth. They are also active organisms in degrading organic materials and remediating heavy metals and pollution in soils, as well as soil-water binders. In addition, microbes that occupy the plant rhizosphere release biochemicals that have nontoxic effects on the host and the environment. These biochemicals could act as biocides in controlling agricultural pests, pathogens, and diseases. Therefore, it is important to consider the use of microbes for sustainable food production.

“…It was reported that the Si-nanoparticle have been used as nutrient carrier such as urea to promote plant growth and development as well as nanosensor for crop monitoring. Si-NPs have also been used to improve soil fertility and water retention capacity in mitigating the environmental stresses due to high salinity, drought and heavy metal pollutions (reviewed by Ng et al, 2021) as illustrated in Figure 1.…”

The naturally occurring and synthesised nanoparticles (NPs) display significant effects on the physiology of plants. This paper emphasised the current application of synthetic NPs in agriculture, several advantages and physiological responses during the growth of plants. Nano pore size of particles provides higher surface areas hence enhances the water holding capacity of the soil, efficacy delivery of fertilisers and pesticides (pest and diseases infestation) on crops. The application of NPs via soil or mist involves uptake by plant via roots or foliar cell wall and translocation to other organs through vascular system and plasmodesmata within the cells. The physicochemical properties of NPs have advantages including enabling the increase of soil water retention in mitigating the drought and/or salinity stresses in plants. Nanoparticles enhance the germination of seed and maintain plant growth by promoting the production of enzymes in scavenging oxygen radicals, phytohormone balancing, nutrient metabolisms and expression of amino acid biosynthetic genes and photosystem. Given the diverse physiological and molecular effects of NPs, precautionary steps prior to their application either as fertiliser or carrier should be considered to avoid toxicity and destructive effects on plants, animals, water body and the environment.
