The efficiency of microorganisms in

The efficiency of microorganisms in degrading PHs is generally
investigated in soil microcosms following solid phase (SOP) bioremediation, but rarely by slurry phase (SLP) bioremediation (Nano
et al., 2003). Water phase is added in SLP to enhance the physical
mixing, whereas in SOP only nutrients are added and the soil bed is
agitated mechanically at intervals (Megharaj et al., 2014). Nonetheless, SLP bioremediation is much faster than many other
bioremediation techniques (Eziuzor and Okpokwasili, 2013; Saez
et al., 2014), and is very useful in cases where the contaminants
need to be broken down very quickly
