“…Among them, atrazine inhibited the activities of sucrase and catalase, but activated soil urease and cellulase. Most soil enzymes are extracellular metabolites secreted by soil [ 54 , 55 ]. The application of atrazine altered the structure and abundance of soil microbial community, thus affecting the activity of soil enzymes [ 21 ].…”

Bioremediation of atrazine-contaminated soil is considered a safe and effective approach in removing contaminates from the soil. However, the effects of adding foreign organisms to assist bioremediation on soil environmental quality and ecosystem are unclear. Here, the ecological remediation potential of strain Paenarthrobacter ureafaciens ZF1 on atrazine-contaminated soil was investigated through miniature experiments using variations in soil enzymes and bacterial communities as indicators. The results showed that strain ZF1 accelerated atrazine degradation, which could completely degrade atrazine at concentrations of 100 mg·L− 1 atrazine within 2 h in liquid medium and could remove up to 99.3% of atrazine (100 mg·kg− 1 in soil) within 6 days. During soil bioremediation, atrazine promoted the activities of urease and cellulase, and inhibited the activities of sucrase and catalase, while the strain ZF1 significantly promoted the activities of these four enzymes. High-throughput sequencing of 16S rRNA genes showed that ZF1 affected the relative abundance and bacterial community structure, and promoted bacterial diversity and evenness. Furthermore, redundancy analysis revealed a certain correlation among the strain ZF1, atrazine residue, soil enzyme activity, and soil bacterial community. The strain ZF1 in this work demonstrated remarkable potential for ecological restoration, and can be an effective and environmentally friendly alternative in remediating atrazine-contaminated soil.

“…It was placed at 37°C for 20 min, and the absorbance value was recorded at 578 nm. Sucrase activity was determined according to the method proposed by Yang et al (2020). The mixture system for assessing soil sucrase activity was obtained by mixing soil with the solution of 8% sucrose at a ratio of 1:3 (w/v), followed by adding 5 ml of phosphate buffer and 5 ml of toluene.…”

Biochar application ameliorated the nutrient content and fungal community structure in different yellow soil depths in the karst area of Southwest China

et al. 2022

The influence of biochar on the change of nutrient content and fungal community structure is still not clear, especially in different yellow soil depths in karst areas. A soil column leaching simulation experiment was conducted to investigate the influence of biochar on soil content, enzymatic activity, and fungal community diversity and structural composition. Three biochar amounts were studied, namely, 0%(NB, no biochar), 1.0%(LB, low-application-rate biochar), and 4.0% (HB, high-application-rate biochar). The results showed that biochar increased the pH value and the contents of soil organic matter (SOM), total nitrogen (TN), available phosphorus (AP), and available potassium (AK) but reduced the microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN). Furthermore, this effect was enhanced with increasing biochar amount. Biochar was conducive to improving the nutrient availability in topsoil (0–20 cm), especially TN, AK, and MBN. Meanwhile, biochar affected the enzymatic activity, especially the sucrase activity. Biochar affected the diversity and structure of the fungal community, of which HB treatment had the most obvious effect. Among these treatments, Aspergillus, unclassified_Chaetomiaceae, Mortierella, Spizellomyces, Penicillium, Fusarium, and unclassified_Chromista fungal genera were the highest. Moreover, biochar inhibited the growth of harmful pathogens and increased the abundance of beneficial fungi in soil, and the effect was enhanced with increasing biochar amount and soil depth. Redundancy analysis (RDA) showed that AK was an important factor in yellow soil, although the main environmental factors affecting the fungal community structure were different in different soil depths. Overall, biochar had a positive effect on improving the land productivity and micro-ecological environment of yellow soil in the karst area.

“…macrolides, sulfonamides, tetracyclines and uoroquinolones -FQs) and antibiotic resistant bacteria or genes in poultry litter and soil samples from Brazil (Leal et al 2012;Parente et al 2019), Canada (Furtula et al 2010), China (Wei et al 2019;Gu et al 2019) and the United States (Cook et al 2014). Among antibiotics, FQ have attracted special attention due to their wide environmental occurrence, soil persistence and adverse effects on terrestrial organisms (Riaz et al 2018;Yang et al 2021). Considering that soils may be associated with multiple contaminants, a trend towards toxicological assessments based on two or more active principles have been proposed (Li et al, 2016;Wang et al, 2019;Wei et al, 2018).…”

Poultry litter is widely applied as a fertilizer even though it is one of the main antibiotic sources for agricultural soils. Long-term sublethal effects (56 days) on the antioxidant system of Eisenia andrei earthworms following exposure to uoroquinolone-contaminated poultry litter (enro oxacin + cipro oxacin) at 5.0, 10 and 20 g kg -1 were evaluated. The following biomarkers were assessed: superoxide dismutase (SOD), catalase (CAT), glutathione-S-trasferase (GST), reduced glutathione (GSH) and a lipid peroxidation (LPO) proxy. Signi cant CAT and SOD increases and a moderate positive correlation (ρ = 0.67, p < 0.05) between these enzymes was observed. Glutathione-S-trasferase levels increased signi cantly at 10 g kg -1 , while GSH exhibited a dose-dependent response at 5.0 mg kg -1 (4 -106%), 10 mg kg -1 (28 -330 %) and 20 mg kg -1 (45 -472%). LPO levels exhibited a decreasing trend with increasing poultry litter concentrations of 8 -170% (5.0 g kg -1 ), 7 -104% (10 mg kg -1 ) and 3 -6% (20 mg kg -1 ). A Principal Component Analysis (PCA) highlighted increased SOD and CAT activities, possibly due to increases in reactive oxygen species (ROS) concentrations. Biological Health Status assessments based on the Biomarker Response Index indicate major alterations in the rst month of exposure, changing to moderate in the second month. These ndings indicate an antioxidant system attenuation trend. It is possible, however, that successive poultry litter applications may reduce the long-term recovery capacity of the evaluated biomarkers.
