Table 2.

Comparison of maximum specific growth rate, % COD reduction, biomass produced, and bio-oil content for different process inoculums.

Wastewater process inoculum type	Maximum specific growth rate	Time required for 90% COD reduction	Total biomass produced	Bio-oil content
	mg VSS/mg VSS·d	hrs	gm/lit	% w/w
Mucor circinelloides	1.083	>96	0.60	22.11
Trichoderma reesei	0.498	>96	0.68	9.82
Conventional bacterial process*	1.343	48	1.55	3.21

^*The bacterial inoculum used in this process was collected from tube settler of MBBR plant, containing mixed bacterial flora.
