Fig. 2From: Valorisation of cotton post-industrial textile waste into lactic acid: chemo-mechanical pretreatment, separate hydrolysis and fermentation using engineered yeastGlucose yields obtained with different pretreatment conditions of cotton waste material. NENC: No Enzymes No Chemical pretreatment control, mechanically treated sample exposed to the same buffers and solutions, without chemical and enzymatic treatments. NE: No Enzymes control, mechanically and chemically pretreated sample without the addition of enzymes. NC: No Chemical pretreatment control, only mechanically pretreated sample with the addition of enzymes. LG: mechanical and chemical pretreatments, with Lab Grade NaOH and hydrolysis. IG: mechanical and chemical pretreatments with Industrial Grade NaOH and hydrolysis. EWW: mechanical and chemical pretreatments with Effluent Wastewater containing NaOH. a p < 0.05 compared to NENC, b p < 0.0001 compared to NC, c p < 0.0001 compared to IG 20% and IG10%Back to article page
