Bioremediation of Parboiled Rice Effluent Supplemented with Biodiesel-Derived Glycerol Using Pichia pastoris X-33

Figure 1

Chemical oxygen demand (COD), phosphorous (P-PO₄₃₋), nitrogen (TKN), and biomass after 70 h of culture in effluent from parboiled rice industry, with or without p.a. or biodiesel glycerol. AP: plain effluent from rice parboiled maceration tanks; AP/G5 supplemented with 5 g·L⁻¹ of p.a. glycerol.; AP/G15 with 15 g·L⁻¹ p.a. glycerol; AP/B5 with 5 g·L⁻¹ of biodiesel glycerol; AP/B15 with 15 g·L⁻¹ of biodiesel glycerol. Different superscripts letters: significant differences (𝛼=0.05).
