Biochar-derived dissolved organic matter (BDOM) plays key roles in soil ecosystem by affecting physicochemical and biological properties supplying nutrients to microbes. It can either enhance or suppress the growth of certain microorganisms, depending on its composition content labile compounds. This review aims discuss summarize role BDOM modifying microbial functioning, community structure, enzymatic activity. We mainly focus as a function concentration, type feedstock biomass, pyrolysis temperature (PT). Results show that saw dust- manure-based biochars produce higher concentrations than straw-, bone-, sludge-based biochars. The types biomass PT determine characteristics interaction with communities. Plant-derived biochar ≤300 °C often results more aliphatic ≥500 °C, which yields aromatic BDOM. plant contains specific ultraviolet absorbance (SUVA) humification index (HIX) manure biochar. SUVA HIX positively correlate (R2=0.68–0.96) total fatty acid methyl esters, but negatively abundances actinomycetes, arbuscular mycorrhizae, fungal However, environmental fate amended requires long-term experiment, both laboratory field scales, provide full understating microorganisms help tailor safe utilization agroecosystems.

Biochar is a carbonaceous material derived from the pyrolysis of carbon-rich biomass that has attracted increasing research and attention because its ability to enhance soil carbon storage, increase fertility, fix transform pollutants in soil, improve environment. These enhancements directly or indirectly affect microorganisms’ metabolic activities community structure. This paper reviews effects biochar on physicochemical properties, enzyme activities, nutrients, contaminants, related microbial activities. In addition, this work summarises possible mechanisms involved interaction between microorganisms potential hazards associated with use. Finally, study aims provide theoretical basis for future research.
