“…As compared to the observed values, a prominent difference of elevated Zn concentration was studied by Ogundiran et al (2012) in the cow feces of control (56.5 mg/kg) and contaminated sites (83.6 mg/kg). The enhanced level of Zn also showed correspondence with the ndings of Svane and Karring (2019) whereas the Omonona et al (2019) studied the 0.04-0.17 mg/kg value in the dry season that was identi ed as a lowered one as compared to examined range of this study. Animal body receives the Zn metal mainly from Soil-Plant system.…”

“…These samples were rinsed with acetone and then follow distilled water to remove external contamination. Further, they were dried in oven for at least 3-4 days and then they are ready for digestion (Gabryszuk et al, 2018) The collected fecal samples are taken directly from the selected animals upon excretion to avoid further contamination (Svane and Karring, 2019). Labeled samples are stored in plastic bags.…”

Heavy metal pollution has thoroughly worldwide apprehensions due to the instantaneous growth of industries. Farming regions are irrigated mainly with wastewater which contains both municipal and industrial emancipations.Therefore, three sites irrigated with ground, canal and municipal-wastewater in the District Jhang were selected to determine the zinc accumulation and its transfer in the soil, plant and animal food-chain. Soil, forage and animal samples of cow, buffalo and sheep were selected from each site. Various pollution indices were also measured to assess the zinc exposure to grazing animals. Zinc concentration was ranged as 18.85-35.59mg/kg in the soil, 26.42-42.67 mg/kg in the forage and 0.982-2.85mg/kg in the animal samples. Investigated zinc concentration in soil and forages was found to be within the recommended WHO/FAO limits but blood samples exceeding the standards of NRC ( 2007). Maximum level of pollution load index (0.427-0.805mg/kg) and enrichment factor (0.373-0.894 mg/kg) for zinc was noticed upon waste water irrigation. Daily intake (0.039 to 0.082 mg/kg/day) and health risk index (0.130 to 0.275 mg/kg/day) of zinc metal was higher in the buffaloes that feed on waste water irrigated forages. Bio-concentration factor (0.840 to 2.01mg/kg) for soil-forage was >1 represented that these plants accumulated the zinc concentration into their tissues and raised health issues in grazing animals on consumption of waste water contaminated forages. Overall ndings of this study, suggested that animal herds should be monitored periodically to devise preventive measures regarding the toxic level of heavy metals availability to livestock.

“…Eisenia spp . earthworms are epigeic species that thrive in organic waste and manure (Domínguez and Edwards 2010 ), and the Zn concentrations in these materials can reach 245–607 mg Zn kg −1 and 79–315 mg Zn kg −1 , respectively (Ozores-Hampton et al 1997 ; Ogiyama et al 2005 ; Terzano et al 2008 ; Svane and Karring 2019 ). The texture and physicochemical properties of these media are drastically different from those of Lufa 2.2 loamy sand soil.…”

In this study, the effects of zinc nanoparticles (ZnO-NPs) and ions (ZnCl2) on the mortality, growth, maturation, and cellular respiration of the earthworm Eisenia andrei were assessed. Earthworms were individually exposed for 98 days, starting from the juvenile stage, to soils contaminated with either ZnO-NPs or ZnCl2 (125, 250, 500 and 1000 mg Zn kg−1 dry weight (dw)). Exposure to the highest-concentration ionic treatments (500 and 1000 mg kg−1) caused 100% mortality, while for other treatments, mortality did not exceed 15% at the end of exposure. Compared to the control treatment, both 125–1000 mg kg−1 ZnO-NPs and 125 or 250 mg kg−1 ZnCl2 stimulated earthworm growth, which might be due to a hormetic effect. ZnO-NPs and ZnCl2 caused different responses at medium Zn concentrations (250 and 500 mg kg−1): earthworms exposed to ionic treatment at 250 mg kg−1 were characterized by a significantly lower growth constant, lower cellular respiration rate, later inflection point, and higher final body weight than those exposed to ZnO-NPs treatments at the same (250 mg kg−1) or twice as high (500 mg kg−1) nominal Zn concentrations. However, differences were not observed in all examined parameters between the studied forms when the highest-concentration ZnO-NPs treatment was compared with the lowest-concentration ionic treatment, which was likely due to the same levels of available Zn concentrations in those treatments. Overall, different growth and maturation strategies accompanied by pronounced differences in cellular respiration were adopted by earthworms exposed to low and medium levels of either ZnO-NPs or ZnCl2.

“…Previously, it was found that manure slurry from pigs contains 11.54 µM Ni 2+ , which is more than enough to maintain ureolysis. (Svane & Karring, 2019) In summary, the ureolytic activity assay with the M9U medium is capable of screening cell-based and cell-free urease activity with a medium-to-high-throughput setup. The assay distinguishes itself from other related methods by using an optimized defined M9-based urea medium (M9U), which differs from other urea media based on M9 medium by having a lower buffer capacity, lower urea concentration, and lower nickel content, which altogether allow for increased sensitivity.…”

The enzyme urease is widespread in nature and catalyzes the hydrolysis of urea to form ammonia and carbonic acid. The high proficiency of the enzyme is associated with a wide range of societal challenges. In agriculture, bacterial urease activity leads to loss of fertilizer through NH3 emission, which has a negative impact on the environment and human health. Urease is also an essential virulence factor for several pathogenic bacteria. To screen for potential urease inhibitors, efficient, sensitive, and accurate urease activity assays are needed. However, most urease activity assays are labor‐intensive and become time‐consuming when used to screen multiple samples. Based on systematic optimization, we have developed a urea‐containing growth medium and method for continuous real‐time monitoring and screening of urease activity from both bacterial cells and pure urease in a plate reader setup. The defined M9‐based urea (M9U) medium was found to be more sensitive and suitable for a plate reader setup than both Christensen's urea broth (CUB) and Stuart's urea broth (SUB), which are established and well‐known complex urea media that formed the principle foundation of M9U. Furthermore, we show that urease activity measurements using the M9U medium in our plate reader‐based method allow reliable high‐throughput screening of urease inhibitors.
