“…Urease activity change in response to treatment appears to result from fertilizer incorporation. Incorporation of fertilizer had a significant effect on the soil urease activity compared to when biochar was added alone, suggesting that the addition of urea in the fertilization regime enhanced the activity of many enzymes catalyzing N. However, single application of biochar without fertilization still showed significant difference with the control soil and this result is consistent with urease and phosphodiesterase activity data obtained in many previous studies [44][45][46]. However, a significant difference of phosphodiesterase activity due to the phosphate addition in the biochar amended soil co-applied with fertilizer (FPK and FRH) was not observed.…”

Soil microbial properties are frequently used as indicators of soil fertility. However, the linkage of these properties with crop biomass is poorly documented especially in biochar amended soil with high carbon:nitrogen (C:N). A short-term field trial was conducted to observe the growth response of maize to biochar treatment in a highly weathered Ultisol of humid tropics and to observe the possible linkage of the measured microbial properties with maize biomass. Soil microbial biomass (carbon (C), nitrogen (N), phosphorus (P)), enzyme activity (β-glucosidase, urease, phosphodiesterase) and gene abundance (bacterial 16S rRNA, fungal ITS) were analyzed. For comparison, total soil C, N, and P were also analyzed. The data revealed no significant linkage of soil C, N, and P with maize biomass. A significant association of enzyme activity and gene abundance with maize biomass was not recorded. Strong positive correlation between maize above ground biomass with microbial biomass N was found (r = 0.9186, p < 0.01). Significant negative correlation was recorded between microbial biomass C:N with maize biomass (r = −0.8297, p < 0.05). These statistically significant linkages observed between microbial biomass and maize biomass suggests that microbial biomass can reflect the soil nutrient status, and possibly plant nutrient uptake. Estimation of microbial biomass can be used as a fertility indicator in soil amended with high C:N organic matter in the humid tropics.

“…Ahmad et al (2016) observed that biochar produced at a low temperature could increase the abundance of fungi, Gram-positive, and Gram-negative bacteria, actinobacteria, and actinomycetes in a Pb-and As-contaminated soil. As a result, the capacity of biochar to change the soil pH, organic matter content, and available nutrients has a great impact on soil microbial activity in contaminated soils amended with biochar (Beesley et al 2010(Beesley et al , 2011Huang et al 2017).…”

“…The reduced bacterial communities at the early stages can be attributed to the accelerated microbial succession caused by biochar-induced microbial activities and growth. As a result, the dominant microbes may occupy the space and consume the nutrients rapidly which lead to inhibit the other microorganism (Huang et al 2017). On the other hand, reduction of metal toxicity caused by biochar and the changes in environmental conditions over the time could account for the increased bacterial community at the later stages (Chen et al 2017b).…”

Application of biochar to soils changes soil physicochemical properties and stimulates the activities of soil microorganisms that influence soil quality and plant performance. Studying the response of soil microbial communities to biochar amendments is important for better understanding interactions of biochar with soil, as well as plants. However, the effect of biochar on soil microorganisms has received less attention than its influences on soil physicochemical properties. In this review, the following key questions are discussed: (i) how does biochar affect soil microbial activities, in particular soil carbon (C) mineralization, nutrient cycling, and enzyme activities? (ii) how do microorganisms respond to biochar amendment in contaminated soils? and (iii) what is the role of biochar as a growth promoter for soil microorganisms? Many studies have demonstrated that biochar-soil application enhances the soil microbial biomass with substantial changes in microbial community composition. Biochar amendment changes microbial habitats, directly or indirectly affects microbial metabolic activities, and modifies the soil microbial community in terms of their diversity and abundance. However, chemical properties of biochar, (especially pH and nutrient content), and physical properties such as pore size, pore volume, and specific surface area play significant roles in determining the efficacy of biochar on microbial performance as biochar provides suitable habitats for microorganisms. The mode of action of biochar leading to stimulation of microbial activities is complex and is influenced by the nature of biochar as well as soil conditions.

“…To overcome these shortcomings, great efforts have been committed to develop peroxidase mimetics. Among them, many peroxidase mimetics, such as porphyrin, hemin, cyclodextrin, and hematin, have been successfully developed and applied to H 2 O 2 detection . Since it was reported first that Fe 3 O 4 magnetic nanoparticles (MNPs) possessed intrinsic peroxidase‐like activity in 2007, thus opening the door for the development of nanomaterial‐based peroxidase‐like.…”

Diabetes is a dominating health issue with 425 million people suffering from the disease worldwide and 4 million deaths each year. To avoid further complications, the diabetic patient blood glucose level should be strictly monitored despite there being no cure for diabetes. Colorimetric biosensing has attracted significant attention because of its low cost, simplicity, and practicality. Recently, some nanomaterials have been found that possess unexpected peroxidase‐like activity, and great advances have been made in fabricating colorimetric glucose biosensors based on the peroxidase‐like activity of these nanomaterials using glucose oxidase. Compared with natural horseradish peroxidase, the nanomaterials exhibit flexibility in structure design and composition, and have easy separation and storage, high stability, simple preparation, and tunable catalytic activity. To highlight the significant progress in the field of nanomaterial‐based peroxidase‐like activity, this work discusses the various smart nanomaterials that mimic horseradish peroxidase and its mechanism and development history, and the applications in colorimetric glucose biosensors. Different approaches for tunable peroxidase‐like activity of nanomaterials are summarized, such as size, morphology, and shape; surface modification and coating; and metal doping and alloy. Finally, the conclusion and challenges facing peroxidase‐like activity of nanomaterials and future directions are discussed.
