“…At present, atrazine degradation genes have been extensively investigated and proven to be highly conserved in many bacteria ( de Souza et al, 1998 ; Singh and Jauhari, 2017 ). According to the different genetic compositions, atrazine-degrading bacteria are divided into two types.…”

“…This result was consistent with Gao et al (2018) and Chen et al (2021) , which was possibly related with two reasons First, with the continuous removal of atrazine after inoculation of P. ureafaciens ZY, the inhibition effect of atrazine on soil microorganisms gradually decreased ( Ros et al, 2006 ). Secondly, most microorganisms in the soil could not have the abllity to metabolize atrazine and cannot directly absorb atrazine as a carbon source and nitrogen source ( Singh and Jauhari, 2017 ). After the decomposition of atrazine by P. ureafaciens ZY, atrazine metabolites could be acted as nitrogen and carbon source by soil microorganisms to meet their growth and proliferation ( Chen et al, 2021 ).…”

An atrazine-utilizing bacterium, designated as ZY, was isolated from agricultural soil and identified as Paenarthrobacter ureafaciens. The P. ureafaciens ZY demonstrated a significant degradation capacity of atrazine, with the degradation efficiency of 12.5 mg L−1 h−1 in liquid media (at pH 7, 30°C, and the atrazine level of 100 mg L−1). The P. ureafaciens ZY contained three atrazine-degrading genes (i.e., trzN, atzB, and atzC) could metabolize atrazine to form cyanuric acid, which showed lower biotoxicity than the parent atrazine as predicted by Ecological Structure Activity Relationships model. A laboratory-scale pot experiment was performed to examine the degradation of atrazine by P. ureafaciens ZY inoculation and investigate its effects on the native microbial communities. The results exhibited that the P. ureafaciens ZY was conductive to the degradation of atrazine, increased the total soil phospholipid fatty acids at the atrazine level of 50, 70, and 100 mg kg−1. By using high-throughput sequencing analysis, Frateuria, Dyella, Burkholderia-Caballeronia-Paraburkholderia were considered as the most important indigenous atrazine-degrading microorganisms due to their relative abundances were positively correlated with the atrazine degradation rate. In addition, P. ureafaciens ZY also increased the abundance of atrazine-degrading genus Streptomyces and Bacillus, indicating that there may be a synergic relationship between them in the process of atrazine degradation. Our work provides a new insight between inoculums and native microorganisms on the degradation of atrazine.

The study on development of solid termite bait matrix and its efficacy against the Heterotermes indicola was performed in Peshawar, during 2023. The study was performed with completely randomized design (CRD) with different treatments i.e., developed bait, patent bait, popular wood and blotting paper. Each treatment was replicated three times. The laboratory experiment consisted of no-choice, free choice and aggregation test. While the semi-field experiment consisted of free choice test. During the no-choice test of the laboratory experiment, H. indicola showed a consumption rate of 6.29% for the popular wood and developed bait. However, in the blotting paper treatment, the termites consumed only 2.81%. In terms of choice test conducted in the lab, the popular wood exhibited the highest weight consumption percentage of 2.87%, while the patent bait displayed the lowest weight consumption percentage of 2.25%. Under the choice test maximum number of termites were attracted towards popular wood (77.00 Number of termites) while minimum number of termites were attracted towards patent bait (54.66 Number of termites). Whereas, in aggregation test, of the lab experiment, maximum number of termites were also aggregated towards popular wood (37.77 Number of termites) while minimum termites were aggregated for patent bait (25.22 Number of termites). In the case of free choice under semi-field conditions, the highest number of termites were observed on popular wood i.e., 380.00 followed by the developed bait, which recorded 293.50 termites. On the other hand, the lowest number of termites were recorded on the patent bait i.e., 231.50. Similarly, when considering the maximum consumed weight in percentage, popular wood exhibited the highest value at 16.24%, closely followed by the developed bait at 15.67% while the patent bait displayed minimum consumed weight percentage of 12.89%. In overall experiments it is concluded that among all the tested treatments, termites mostly consumed popular wood and developed bait. Since the developed bait showed promising results in attracting termites, it is recommended to continue refining its formulation. Conduct additional research to identify the key components or additives that enhance its attractiveness and consumption by termites. This optimization process can help maximize the effectiveness of the bait as a termite control strategy. Adding more popular wood saw dust in the bait may achieve more significant and desired results and can also prove to be cost efficient rather than adding more cellulosic material.

English Judicial Approach towards Piercing the Corporate Veil after Prest v Petrodel

The application of the evasion principle by Lord Sumption in Petrodel v Prest is critically inspected and investigated to highlight how the doctrine of piercing the corporate veil has been applied by the English Courts. To this end, it is pinpointed that the scope of the doctrine has been narrowed, and the courts frequently misinterpreted the evasion principle, as evinced by the recent case Akhemodova v Akhemdov and Wood v Baker
