“…The literature on the causes of gender inequality also contributes to the proposed research. In various areas of life, current studies have investigated drivers of gender disparity, such as political factors (Saleem et al , 2017), education-related factors (Mujahid et al , 2019; ur Rahman et al , 2018), wage-related factors (Jaffri et al , 2015) and cost-related factors (Shahriari et al , 2009). However, there is minimal empirical data on the effects of gender discrimination in the formal financial sector of legal and policy empowerment initiatives.…”

Purpose This paper aims to address the issues of Asian countries toward why females are discouraged and more likely to be removed from the formal financial system than males. Further, whether there is any connection between religion and women’s financial inclusion is also addressed. Design/methodology/approach This paper explores gender disparities in the use of structured financial services through multilevel models tailored to the individual. The data from 2004 to 2017 have been used for eight South Asian countries, including Bangladesh, India, Pakistan, Sri Lanka, Afghanistan, Maldives, Nepal and Bhutan. We used a multilevel modeling methodology to estimate the impact of the socio-economic climate on women’s financial inclusion while controlling for individual-level features, with all control variables included, the two-level logistic regression model used for this study. Findings The results of this study demonstrate that sex appears to be strongly correlated with the usage of financial services. The study also found that in nations where religious restrictions limit women’s willingness to work for a living, they are less likely than males to own a bank account. However, through legislation and regulations, countries that encourage gender equality in the labor market and have effective regulatory mechanisms to maintain these initiatives appear to have more financially active women. Practical implications This research advises that government authorities strengthen women’s empowerment in South Asian countries. Originality/value To the best of the authors’ knowledge, this is the first paper that explains the linkage between financial inclusion and women empowerment and will contribute to existing knowledge.

“…Bacterial strain with lead resistance system initiates the synthesis of metallothioneins upon higher exposure of lead toxicity. This phenomenon was reported in several bacterial species (Bacillus megaterium, Proteus penneri GM-10, Providencia vermicola strain SJ2A, P. aeruginosa strainWI-1, Salmonella choleraesuis, and Streptomyces sp., 4A [28,29,31]. In the bacterial system, the presence of genomic DNA metal-binding metallothionein genes such as bmtA and smtAB may be attributed to the intracellular sequestration of lead and reduced toxicity.…”

Excessive lead accumulation is a severe concern for the environment as its toxicity is associated with soil microbial diversity, agricultural production, and human health. Physico-chemical methods of remediation of lead from the existing environment are generally costly and also not efficient due to the production of another form of the toxic compound. Bioremediation has been now considered the most efficient method to remove heavy metals from the surrounding by using microorganisms and plants. Microbes are generally more resistant than any eukaryotic organism and act as a key player in mitigating lead toxicity. The absorption and accumulation of toxic metals by bacteria exhibit many metabolically related and independent processes. Biotransformation, biosorption, precipitation, and encapsulation are the most efficient strategies opted by the microbial system to remediate lead metal from wide sources such as soil, sludge, and wastewaters to clean the environment. Genetically improved bacterial strains have good efficiency and have multiple modes of remediation from soil and other industrial waste. However, environmental biotechnology has not yet explored many aspects of the interaction between metals and microorganisms, and further development and applications are needed to deliver the non-toxic form of lead into the ecosystem. This review also highlights the potential of lead-resistant bacteria used as a biosensor for lead contamination sites.
