“…Certain soil bacteria decompose biuret (Aukema et al., 2020; Cameron et al., 2011; Esquirol et al., 2018, 2020; Jensen & Schrøder, 1965; Martinez et al., 2001; Robinson et al., 2018). Biuret in soil occurs as an impurity of urea fertilizer.…”

“…It is also produced by the degradation of cyanuric acid, an intermediate metabolite of s ‐triazine compounds such as melamine and atrazine (Aukema et al., 2020). The evolution of biuret catabolizing enzymes in bacteria is considered to be associated with the use of urea fertilizer and s ‐triazine herbicide (Esquirol et al., 2020; Robinson et al., 2018). One molecule of biuret is converted into three ammonium and two bicarbonate ions via the biodegradation pathway.…”

“…Although it is not known yet how much biuret plants would take up and accumulate, introduction of biuret hydrolase from soil bacteria might contribute to biuret detoxification in plant cells. Furthermore, biuret could act as a slow‐release N fertilizer as researchers have suggested (Esquirol et al., 2020; Sahrawat, 1981) and as a weed controller (Figure ) if we could confer the biuret‐detoxifying ability to crop plants.…”

Urea, currently the most widely used nitrogen (N) fertilizer worldwide (IFASTAT, https://www.ifast at.org/datab ases), might contain biuret [(CONH 2) 2 NH], as a common impurity. Biuret is formed by the thermal condensation of urea. It has been known since the 1950s that excessive amounts of biuret in urea fertilizers cause injury in crops (Jones, 1954; Sanford et al., 1954). A wide range of crops can be potentially affected by biuret toxicity, which often manifests as leaf chlorosis and stunted growth, especially in the young seedling stage (Mikkelsen, 1990). Earlier studies indicated that biuret inhibited protein synthesis in Xanthium pensylvanicum leaves (Webster et al., 1957) and wheat (Triticum aestivum) germplasms (Ogata & Yamamoto, 1959). The protein content, however, did not so much decrease in biuret-injured orange (Citrus sinensis) leaves (Impey & Jones, 1960). It remains uncertain whether biuret has a direct effect on the protein synthetic machinery. Additionally, ultrastructural analyses showed that changes in chloroplast structure in biuret-injured leaves were similar to those in senescent leaves in grapefruit (Citrus paradise) and orange plants (Achor & Albrigo, 2005). Moreover biuret seems to remain unmetabolized in plants, because it was still detected in orange leaves, eight months after foliar spraying was performed (Impey & Jones, 1960). The exact mechanism underlying biuret toxicity in plants, however, is still far from being understood.

“…PFAS were first deployed over 70 years ago in the 1950s. Pesticides, such as triazine herbicides and organophosphate insecticides, were introduced in the same 1950s and 1930s, respectively, and microbial degradation of these compounds has been observed and characterized in molecular detail since before the start of this millennium ( 33 , 191 ). None of these compounds are toxic to bacteria but instead provide access to otherwise limited nutrients, providing a selective pressure by virtue of the growth advantage their catabolism provides ( 192 ).…”

“…In contrast, biodegradation provides a potentially favorable alternative approach for achieving complete PFAS degradation via a low-cost, environmentally friendly technology. Biodegradation using microbes or cell-free enzymes has been demonstrated to be technically effective for a range of contaminants, including herbicides ( 33 ), insecticides ( 34 , 35 ), fungicides ( 36 – 38 ), and industrial solvents ( 39 , 40 ). The biodegradation of naturally occurring and synthetic organochlorides has been investigated and documented extensively ( 41 , 42 ).…”

Per- and polyfluoroalkyl substances (PFAS) are highly fluorinated synthetic organic compounds that have been used extensively in various industries owing to their unique properties. The PFAS family encompasses diverse classes, with only a fraction being commercially relevant. These substances are found in the environment, including in water sources, soil, and wildlife, leading to human exposure and fueling concerns about potential human health impacts. Although PFAS degradation is challenging, biodegradation offers a promising, eco-friendly solution. Biodegradation has been effective for a variety of organic contaminants but is yet to be successful for PFAS due to a paucity of identified microbial species capable of transforming these compounds. Recent studies have investigated PFAS biotransformation and fluoride release; however, the number of specific microorganisms and enzymes with demonstrable activity with PFAS remains limited. This review discusses enzymes that could be used in PFAS metabolism, including haloacid dehalogenases, reductive dehalogenases, cytochromes P450, alkane and butane monooxygenases, peroxidases, laccases, desulfonases, and the mechanisms of microbial resistance to intracellular fluoride. Finally, we emphasize the potential of enzyme and microbial engineering to advance PFAS degradation strategies and provide insights for future research in this field.
