E nature the nature of matrix: derivatives of HA humic acids is going to be characterized by depend on from the humic the humic matrix: derivatives of HA humic acids are going to be characa slowed a slowed reaction rate as in comparison to the of fulvic acids. In the exact same time, terized byreaction price as compared to the derivatives derivatives of fulvic acids. At the the type of modifier utilized for incorporation in to the initial the initial humic ensemble precisely the same time, the kind of modifier employed for incorporation intohumic ensemble will definewill worth of its antioxidant capacity. It may be concluded that the directed modification of define the value of its antioxidant capacity. It could be concluded that the directed modiHS with phenolic phenolic a promising tool for preparing humic antioxidants with the fication of HS withcenters is centers is usually a promising tool for preparing humic antioxidants desired preferred properties (KL1333 medchemexpress Figure eight). with theproperties (Figure 8).Figure eight. Humic and fulvic derivatives as electron acceptors and donors. Figure eight. Humic and fulvic derivatives as electron acceptors and donors.We’ve not too long ago demonstrated good prospects of this approach for suppressing We emission by consortium great prospects of bacteria [46]: addition of 2-OH methanehave not too long ago demonstrated of methanogenic this approach for suppressing methane emission by consortium of into Leukotriene D4 In Vivo cultivation medium substantially 2-OH-naphtho-naphthoquinone-HA-derivative methanogenic bacteria [46]: addition ofreduced the price quinone-HA-derivative into cultivation medium substantiallyof fulvic the price and the and also the level of the emitted methane, while addition decreased acids and their amount of the emitted methane, whilethe production of methane. From an agricultural hydroquinone derivatives stimulated addition of fulvic acids and their hydroquinone viewpoint, it could possibly be suggested that of methane. From an agricultural point of view, it derivatives stimulated the production fulvic acids, in particular, those modified with hydroquinones, could that fulvic acids, in specific, those modified with associated to ability may well be suggestedpossess enhanced electron-shuttling capacity, that is hydroquinones, of humic substances for eliciting biostimulating activity on plant growth [47]. If slow-acting could possess enhanced electron-shuttling capacity, that is connected to ability of humic agents are for eliciting biostimulating activity on to humic acids and slow-acting agents substances required, the preference needs to be givenplant development [47]. If their derivatives. are needed, the preference need to be offered to humic acids and their derivatives.Author Contributions: Conceptualization, I.V.P.; methodology, A.B.V., A.Y.Z., E.N.N. and D.S.V.; investigation, N.V.M., A.B.V., A.I.K., A.A.M. and S.V.M.; writing–original draft E.N.N., D.S.V.; inAuthor Contributions: Conceptualization, I.V.P.; methodology, A.B.V., A.Y.Z.,preparation, A.B.V., N.V.M., A.E.B. plus a.B.V., A.I.K., A.A.M., and editing, I.V.P., A.Y.Z. and preparation, A.B.V., vestigation, N.V.M.,M.E.G.; writing–review S.V.M.; writing–original draftM.V.Z.; visualization, A.B.V.; A.E.B., acquisition, I.V.P.
