Abstract

In the era of science and modern technology, environmental pollution is still the threat to survival of mankind. With the increasing urbanization process, anthropogenic sources of toxic heavy metals like mercury, lead, arsenic, chromium are also rising rapidly. Inadequate measures have been taken to mitigate the detrimental effects of such pollution. Among many mitigations process like physical, chemical and biological methods; microbial remediation is eco-friendly and cost-effective process and converts the toxic substances to the least toxic forms. By the blessing of modern science, various advanced molecular techniques (i.e. genetically modified organisms) can also be utilized. This review article summarizes the mitigation techniques of toxic heavy metals with emphasis to microbial remediation. However, more research is required to make them more expedient for mass use. Above all the remedies, cognition and circumspection are the exigent demands. Stamford Journal of Microbiology, 2023. Vol. 13, Issue 1, p. 42-51

减轻重金属污染--孟加拉国微生物修复与前景概述
在科学和现代科技发达的时代,环境污染仍然是人类生存的威胁。随着城市化进程的加快,汞、铅、砷、铬等有毒重金属的人为来源也在迅速增加。目前还没有采取足够的措施来减轻这些污染的有害影响。在物理、化学和生物方法等众多缓解过程中,微生物修复法是一种生态友好、经济高效的方法,可将有毒物质转化为毒性最小的形式。得益于现代科学的发展,各种先进的分子技术(即转基因生物)也可以得到利用。这篇综述文章总结了有毒重金属的缓解技术,重点是微生物修复技术。不过,还需要进行更多的研究,使其更便于大规模使用。在所有补救措施中,认知和谨慎是当务之急。斯坦福微生物学杂志》,2023 年。第 13 卷,第 1 期,第 42-51 页
