Individual colonies could be appreciated standing out as dome-shaped growth till 48-72 hours, since the time of inoculation after which the culture gets contaminated with saprophytic bacteria
and other yeasts and moulds.
Application of a rapid method for gram differentiation of plant pathogenic and saprophytic bacteria
Suslow TV, Schroth MN, Isaka M (1982) Aplication of rapid method for Gram differentiation of plant pathogenic and saprophytic bacteria
The majority of the soil microorganisms are nonpathogenic saprophytes, but there also exist such saprophytic bacteria
that are pathogenic for human beings and animals.
The tests are useful in eliminating other saprophytic bacteria
that are normally occur together with the pathogen.
Aerobic saprophytic bacteria
are mainly represented by non spore-formers from the Pseudomonas genus, including fluorescent and pigmented bacteria and mycobacteria.
Phosphorus solubilization is occurs by a huge amount of saprophytic bacteria
and fungi acting on scarcely soluble soil phosphates .
