Nitrogen fertilization increased non-aromatic compounds in WEOC and the stability of WEOC at Breton but not at Ellerslie.
Laccases belongs to multinuclear copper-containing oxidase and can act on a variety of aromatic and non-aromatic compounds.
This reduction is clearly due to the degradation of HA to non-aromatic compounds or conversion to FA-like substances, since there was no fungal biomass present, hence no biosorption could occur.
Laccases have the ability to oxidize a wide range of aromatic and non-aromatic compounds which includes substituted phenols, some inorganic ions, and variety of non-phenolic compounds (Matera et al. 2008; Songulashvili et al. 2016; Nguyen et al. 2016; Surwase et al. 2016).
Laccase (EC 1.10.3.2) is a blue copper oxidase secreted by white rot fungi (WRF) not only an important component of the ligninolytic enzyme system responsible for lignin degradation, but can even degrade non-aromatic compounds in the presence of low molecular weight redox mediator compounds [1].
8, 9 Moreover, the carbon atoms of aromatic compounds are counted in arabic numerals (eg, 1, 2, 3) rather than the Greek letter designations (eg, alpha, beta, gamma) applying to aliphatic structures (non-aromatic compounds).
In general, all analyzed samples produced a mixture of low molecular weight compounds representing different derivatives of aromatic and non-aromatic heterocyclic compounds, and oxygenated compounds, such as phenols, toluene, pyrrole, indolizine, indole, piperidine, pyran, cyclopentene and cyclohexene.
According to experiments that were carried out at 400 °C and 25 MPa, aromatic sulfur compounds do not react in SCW, but SCW can convert non-aromatic sulfur compounds.
The sulfuric compounds in fossil fuels are divided into non-aromatic and aromatic compounds.
This non-aromatic class of compounds have pharmacological importance such as anti-HIV, antibacterial, antiviral, anticancer and anti-inflammatory activities [ 29].
