“…Biological nitrification inhibition (BNI) shows great potential as a component of sustainable agriculture because it uses the natural nitrification inhibitory potential of field crops (Coskun et al 2017;Subbarao et al 2013b;Subbarao and Searchinger 2021;Wendeborn 2020). BNI is a specific ecological phenomenon that occurs in the plant rhizosphere, where secondary metabolites emitted from plant roots inhibit nitrification of nitrifying microbes.…”

To control agronomic N losses and reduce environmental pollution, biological nitrification inhibition (BNI) is a promising strategy. BNI is an ecological phenomenon by which certain plants release bioactive compounds that can suppress nitrifying soil microbes. Herein, we report on two hydrophobic BNI compounds released from maize root exudation (1 and 2), together with two BNI compounds inside maize roots (3 and 4). On the basis of a bioassay-guided fractionation method using a recombinant nitrifying bacterium Nitrosomonas europaea, 2,7-dimethoxy-1,4-naphthoquinone (1, ED50 = 2 μM) was identified for the first time from dichloromethane (DCM) wash concentrate of maize root surface and named “zeanone.” The benzoxazinoid 2-hydroxy-4,7-dimethoxy-2H-1,4-benzoxazin-3(4H)-one (HDMBOA, 2, ED50 = 13 μM) was isolated from DCM extract of maize roots, and two analogs of compound 2, 2-hydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one (HMBOA, 3, ED50 = 91 μM) and HDMBOA-β-glucoside (4, ED50 = 94 μM), were isolated from methanol extract of maize roots. Their chemical structures (1–4) were determined by extensive spectroscopic methods. The contributions of these four isolated BNI compounds (1–4) to the hydrophobic BNI activity in maize roots were 19%, 20%, 2%, and 4%, respectively. A possible biosynthetic pathway for zeanone (1) is proposed. These results provide insights into the strength of hydrophobic BNI activity released from maize root systems, the chemical identities of the isolated BNIs, and their relative contribution to the BNI activity from maize root systems.

“…The enzymatic process of nitrification can be divided into three pathways: NH 3 oxidation pathway, NH 2 OH oxidation pathway, and NO 2 oxidation pathway. The enzymatic process is carried out by an electron transport chain and the reaction is exergonic (a biochemical reaction that releases energy) (Wendeborn, 2019). Ammonia monooxygenase (AMO) turns ammonia into NH 2 OH with the gain of two electrons (Daims et al, 2015).…”

Sustainable intensification is a means that proffer a solution to the increasing demand for food without degrading agricultural land. Maize is one of the most important crops in the industrial revolution era, there is a need for its sustainable intensification. This review discusses the role of maize in the industrial revolution, progress toward sustainable production, and the potential of nitrifying bacteria and archaea to achieve sustainable intensification. The era of the industrial revolution (IR) uses biotechnology which has proven to be the most environmentally friendly choice to improve crop yield and nutrients. Scientific research and the global economy have benefited from maize and maize products which are vast. Research on plant growth-promoting microorganisms is on the increase. One of the ways they carry out their function is by assisting in the cycling of geochemical, thus making nutrients available for plant growth. Nitrifying bacteria and archaea are the engineers of the nitrification process that produce nitrogen in forms accessible to plants. They have been identified in the rhizosphere of many crops, including maize, and have been used as biofertilizers. This study's findings could help in the development of microbial inoculum, which could be used to replace synthetic fertilizer and achieve sustainable intensification of maize production during the industrial revolution.

“…It is estimated a world nitrogen (N) fertilizer demand of around 110.000 thousand tonnes N for 2020 (FAO 2017) . Industrial N fixation to produce ammonium (NH 4 + ) fertilizers accounts for approximately two percent of the world's energy consumption (Wendeborn 2019). But crops use fertilizer N inefficiently as more than 50 % of its N is not assimilated by plants.…”

“…Once checked enough BNI activity on Nitrosomona s sp. in pure cultures, it is necessary to test the effectiveness in the field (Wendeborn 2019). Lu et al (2019) found that 1,9-decanediol decreased AOB and AOA abundance in three different soils and changed AOB community structure.…”
