About the Author: Dr Saranya Kuppusamy obtained MSc in Agricultural Microbiology (2009-11) from the Tamil Nadu Agricultural University, Coimbatore, India. She joined the University of South Australia, Mawson Lakes, Australia in 2012 for her doctoral research with the prestigious International Postgraduate Research Scholarship together with the top-up fellowship from the Cooperative Research Centre for Contamination Assessment and Remediation of the Environment and obtained PhD in Environmental Remediation and Public Health in 2015. Her research findings on 'A new microbial formulation to clean up contaminated sites' have been highlighted in Research Edge Newsletter of the University of South Australia in 2015. Later she joined the Gyeongsang National University, Jinju, South Korea in November 2015 and worked as a Research Professor until June 2018. She received 'Excellent thesis presentation award' offered by the Korean Society of Environmental Agriculture (KSEA) in the International Symposium and Annual Meeting of the KSEA held at Muju, the Republic of Korea in 2016. She has been availing the DST-SERB Ramanujan Fellowship (Scientist D) awarded (2018-23) by the Govt. of India at the Centre for Environmental Studies Anna University, Chennai, India. She has been actively involved in different areas of Agriculture and Environment (Soil chemistry, Fertility and management, Environmental biotechnology, Biochar, Soil and water remediation, Waste management, Crop quality improvement), and published 46 journal articles (over 850 citations, h-index of 16 and i10-index of 23), two book chapters and a book, 'Agricultural and Industrial Microbiology'.
Dr Naga Raju Maddela received MSc (1996-98) and PhD (2012) in Microbiology from Sri Krishnadevaraya University, Anantapuramu, India. During his doctoral program in the area of Environmental Microbiology, he investigated the effects of industrial effluents/insecticides on soil microorganisms and their biological activities. He worked as a faculty in Microbiology for 15 years, teaching undergraduate and postgraduate students. He received 'Prometeo Investigator Fellowship' (2013-15) from Secretaría de Educación Superior, Ciencia, Tecnología e Innovación, Ecuador, and 'Postdoctoral Fellowship' (2016-18) from Sun Yat-sen University, China. He received external funding from 'China Postdoctoral Science Foundation' in 2017 and worked in the area of Environmental Biotechnology. He participated in 19 national/international conferences and presented research data in China, Cuba, Ecuador and Singapore. Currently, he is working as a Professor at Facultad de Ciencias de la Salud, Universidad Técnica de Manabí, Portoviejo, Ecuador. He has 37 research papers to his credit besides co-authoring two books, one published by SpringerBriefs and the other by Springer.

Dr Mallavarapu Megharaj joined the Global Centre for Environmental Remediation (GCER), the University of Newcastle as Professor of Environmental Biotechnology in May 2015. Prior to joining the University of Newcastle, Megh worked as Professor of Environmental Biotechnology (University of South Australia), Senior/Research Scientist (CSIRO Land & Water), and Postdoctoral Fellow (Otago University, New Zealand; GBF-National Research Centre for Biotechnology, Germany; University of Liverpool, UK). Also, for the past 14 years, he has been leading the 'Remediation Technologies Program' within the Cooperative Research Centre for Contamination Assessment and Remediation of the Environment (CRC-CARE). Megh is an internationally recognized expert in the areas of microbial degradation of pollutants and environmental toxicology/remediation. Most of his research involved multidisciplinary teams for which he provided the leadership role. Megh and his colleagues have field implemented and monitored natural attenuation as an effective remedial option for petroleum hydrocarbon-contaminated sites in addition to providing new scientific knowledge on fate and behaviour of emerging contaminants such as firefighting foams. Also, Megh and his colleagues have developed, and field implemented novel bioremediation technologies for petroleum hydrocarbon-contaminated soils. He currently serves as a member of the editorial board for Environmental Geochemistry and Health, and Ecotoxicology and Environmental Safety. He is an author/co-author of 390 refereed journal papers, 18 invited book chapters, five patents and co-editor of four books. He supervised 37 PhD students, and has an h-index of 61, i10-index of 270 and total citations over 13800.

Dr. Kadiyala Venkateswarlu was a Professor of Microbiology, Sri Krishnadevaraya University, Anantapuramu, India until 2011. Taught General Microbiology, Microbial Genetics, Molecular Biology, and Genetic Engineering to MSc students. Served as Dean, Faculty of Life Sciences, and Professor-in-Charge of Biotechnology Department. His research area of interest has been Environmental Biotechnology, particularly concerned with microbial degradation of pollutants and environmental toxicology/remediation.
