Biobleaching of loblolly pine kraft pulp with Trametes trogii culture fluids followed by a peroxide stage. Application of Doehlert experimental design to evaluate process parameters

Evaluation of hematin-catalyzed Orange II degradation as a potential alternative to horseradish peroxidase

“…Furthermore, the strategies for optimization using HRP and RSM have used principally CCD (Ghasempur et al, 2007;Yousefi and Kariminia, 2010;Deyhimi and Nami, 2011). The Doehlert approach has been applied to process design using combinations of fungi and peroxide (Da Re et al, 2010) and for other applications (Zolgharnein et al, 2010), but studies about its application for dye removal using HRP and biomimetics in comparative terms are scarce. A recent review reports on the suitability of Box Behnken and Doehlert optimization designs due to more efficient matrices than CCD.…”

Biopulping of wood chips with Phlebia brevispora BAFC 633 reduces lignin content and improves pulp quality

“…The main objective of the paper manufacturing processes is the removal of lignin from wood; this is the first step in chemical pulping. Kraft pulping is the most widespread process (Da Re et al, 2010). Kraft pulping and bleaching stages use large amounts of chlorine and chloride chemicals (Polaina and MacCabe, 2007;Selvam et al, 2011).…”

Biodegradation of cassava root sieviate with enzymes extracted from isolated fungi

“…Apart from the fact that β-glucans and the insoluble NSPs arabinoxylans are also found in crude fibre and they are in endosperm cell walls. Crude fibres were hydrolyzed by the synergetic action of xylanase and glucanases (Dare et al, 2010;Hughes et al, 2000). Table 3 shows mineral composition of undegraded and degraded cassava root sieviates.…”
