“…The cultivable bacterial diversity was explored extensively from various habitats such as soil (Miwa, 1975;Yi and Chun, 2006;Ruckert, 1985;Shivaji et al, 1988;1989a;1989b;1991;Wery et al, 2003;Bozal et al, 2007), water (Lo Giudice et al, 2012;Michaud et al, 2012;Soller et al, 2000;Labrenz et al, 2000;Cristóbal et al, 2011), algal mats (Reddy et al, 2000;2002;2003a;2003b;Van Trappen et al, 2002;Spring et al, 2003;Peeters et al, 2011), ice Antibus et al, 2012;Bowmen et al, 1998) and sediments (Shivaji et al, 2011;Yu et al, 2011) and reviewed by Shivaji and Reddy (2009) (Hirsch et al, 2004;Antibus et al, 2012;Franzmann & Dobson, 1992;Chattopadyay et al, 2014). Among the Proteobacteria, Gammaproteobacteria leads in abundance in soil (3%) and water (0.6%) while members of Epsilonproteobacteria were absent (Reddy et al, 2016 (Reddy et al, 2016 Chattopadhyay et al, 2014;Reddy et al, 2016).…”
