Isolation and Identification of Actinomycetes
Phosphate-solubilizing actinomycetes have been isolated from diverse environment
(Matsumoto et al.
1998
; Rai et al.
2007
; Lee et al.
2008
) such as soil (Xu et al.
1996
;
Debananda et al.
2009
; Salcedo et al.
2014
), rhizospheres (Norovsuren et al.
2007
),
phyllosphere (Gupta et al.
2010
), and salt and alkaline environments (Jiang
et al.
2005
) (Table
6.1
). The bioprospecting of actinomycetes from the usual or
routine habitat is likely to result in rediscovery or the recovery of the same strain
with the similar mode of actions (Jensen et al.
2005
).
Actinomycetes represent one of the largest domains of bacteria involving
145 genera and more than 4,000 species (Berdys
2005
). Their population has
been reported highest at the soil surface which, however, decreases with increasing
soil depth (Takahashi and Omura
2003
). Prior to isolation, soil is pretreated in order
