TLDR
The results showed that the electron accepting capacity (EAC) and electron donating capacity (EDC) of compost-derived DOM were 3.29-40.14μmole- (gC)(-1) and 57.1- 346.07μmoles- (GC)(1) respectively, which increased the EDC and EAC of the DOM during composting.About:

Effect of organic acids production and bacterial community on the possible mechanism of phosphorus solubilization during composting with enriched phosphate-solubilizing bacteria inoculation.
TL;DR: It is pointed out that inoculation affected pH, total acidity and the production of oxalic, lactic, citric, succinic, acetic and formic acids and a possible mechanism of P solubilization with enriched PSB inoculation, which was induced by bacterial community and organic acids production.
Journal ArticleDOI
Effect of precursors combined with bacteria communities on the formation of humic substances during different materials composting.
TL;DR: An adjusting method to promote HS amount during composting is proposed based on the relationship between the key bacteria communities and the precursors as well as physical-chemical parameters.
Journal ArticleDOI
Remediation of multiple heavy metal-contaminated soil through the combination of soil washing and in situ immobilization.
TL;DR: The combination of soil washing and in situ immobilization is an effective method to amend the soils contaminated with multiple heavy metals and lime was the most effective material, indicating that low soil pH and high acid-soluble metal concentrations might restrain the activity of soil enzymes.
Journal ArticleDOI
Effect of thermo-tolerant actinomycetes inoculation on cellulose degradation and the formation of humic substances during composting
TL;DR: Redundancy analysis showed that the different inoculation phases had different impacts on the relationship between exogenous actinobacteria and physical-chemical parameters, so an optimized inoculation strategy to increase the content of humic substances, alleviate CO2 emission during composting is suggested.

TL;DR: Redundancy analysis enabled the relationship between spectral indices and composting parameters to be explained, demonstrating that these indices can be used for assessing the degree of humification.

TL;DR: In this article, a new approach for parameterizing dissolved organic matter (DOM) ultraviolet-visible absorption spectra is presented, where two distinct spectral slope regions (275-295 nm and 350-400 nm) within log-transformed absorption spectras were used to compare DOM from contrasting water types, ranging from wetlands (Great Dismal Swamp and Suwannee River) to photobleached oceanic water (Atlantic Ocean).

Biodegradation of lignin in a compost environment: a review
TL;DR: The optimum temperature for thermophilic fungi is 40-50°C which is also the optimal temperature for lignin degradation in composting as discussed by the authors, however, very little is known about the degradation by mixed microbial compost populations.

Fluorescence Inner-Filtering Correction for Determining the Humification Index of Dissolved Organic Matter
TL;DR: This study suggests that for quantitative results which can be used to compare humification of natural organic matter across different studies, correction of the fluorescence emission spectra for innerfiltration effects is needed.
