Less than
one part in 1012 of the earths’ soil has been screened for
Actinomycetes (Baltz, 2007). Only 1-3% of Streptomycete
antibiotics have been discovered and to find the remaining 97-99%
will require modern technologies for screening, selection and
enrichment of Actinomycetes (Clardy et al., 2006; Goodfellow,
2010).
