I wish to express my sincerest gratitude to my mentor, the illustrious Professor M K Rai, Head, Department of Biotechnology, Amaravati University, Amravati, Maharastra, for critical suggestions, help, guidance and encouragement all through my research career.

I would like to thank Professor S A Brown, Ex-Principal, Danielson College, Chhindwara, from the core of my heart, for uplifting my spirits in the testing times and augmenting my motivations besides going out of the way to provide me support and lab facilities during my research and showing me a path of courage and success even today.

I wish to express all my thanks to Dr Sanjay Pawar who is gem of a person; he is still active part of my Patalkot mission.

I am delighted to have friends like Dinesh Gautam, Amit Rupda, Raman Gupta, Manish Shrivastava, Pandula Sreehari, Dhananjay Pane, Shailendra Ujwane, Anshu Shrivastava, Alok Shrivastava in my life. They are everything for me.

I would like to express my gratitude to Mr Santosh Gautam, Mr Satyajeet Dholey, Abhijeet Dholey, Sanjay Soni, Ajay Gupta, Poorvi Reddy, Paridhi Nama, Dr Vatsala Sharada, Anitha Babusekhar, Mamta Gupta, Moumita, Reema Bedi and all my friends for being with me always.

Special thanks to Mr Ravindra Nafde, Mr Naveen Malviya (Jeemi), Mr Panna Lal Raut, Mr Lakhan Sahu, Mr Dinesh Shakrawar for supporting me during my research tenure at Danielson College, Chhindwara.

I can not forget to mention about Mr Pradeep Jain (Babla), Paras Printing Press, Chhindwara, whose life inspired me. I learnt how to survive during odds in life. He is my inspiration. I must thank him for boosting me up all the time.

I am delighted to have a sister in Guyana, Mrs Kamini Ramrattan. She encouraged me a lot all these years. Thanks are due to Pooran Jijaji and Beena too for their love and blessings.

I must thank Mr Manish Singh, Ahmedabad for giving his upper hand to me and the love from his family members is greatly admired specially from Nipa Bhabhiji and Daksh.

From the abyss of my heart comes out the uninhibited gratefulness for my respected maternal uncle Dr Ramakrishna Madabhushi, Senior Scientist, Livermore National Laboratory, CA, USA; and to Neeraja Aunty and all other kith and kin for motivating me always.

My sincerest thanks are to due to my tribal folks in Patalkot who shared their valuable knowledge and many more information.

Last but certainly the greatest, lest I am unable to mention the untold patience and sufferings of the divine lights who kept me adrift through the tides of times, my mother (Smt Radha Narayanan), who works as hard as one can, who was there where I needed her the most and who kept burning the oil in me. My Brother (Mr Vijay Acharya), Bhabhi (Mrs Anamika Vijay Acharya) and the cutest possible kiddos with their adorable antics rejuvenated my energy and all dreams that I ever aspired for my niece (Baby Gautami Acharya) and nephew (Master Gautam Acharya). I can not forget the love, care and support given to me by my wife Dr Garima S Acharya. Thanks to you Garima.

Thanks to all of you for being with me always……
