Cellulosic ethanol was produced via simultaneous enzymatic hydrolysis and fermentation of steam pretreated sugarcane bagasse. Sugarcane bagasse underwent steam pretreatments at Log Ro 3.05-4.09, under catalysed (SO2 2% and H2SO4 0.25%) and uncatalysed conditions. Digestibilities of the steam pretreated bagasse were assessed via enzymatic hydrolysis using cellulase (Celluclast 1.5L) and B-glucosida

Popular Abstract in Swedish Ansträngningen att framställa nya förnyelsebara drivmedel har under de senaste årtionden ökat markant. Anledningarna har varit flera, dels oron för klimatpåverkan vid användningen av fossila bränslen, dels från ett nationellt energisäkerhetsperspektiv då lokal produktion skulle kunna stabilisera tillgången. Bioetanol är ett av de största biobränslena i världen och produFuel ethanol from lignocellulosic biomass has the potential to provide a sustainable replacement for traditional oil-based fuels. This dissertation assesses the processing of three different lignocellulosic materials – spruce, wheat straw and giant reed – at industrially relevant solid loadings. The work is divided into two main parts. The first part deals with the degradation of biomass to sugars

Thin-butted flint axes are one of the most frequently occurring types in Scandinavian prehistory. While most of the type's morphological features show a narrow range of variation, the length of whole thin-butted axes can vary from 11 to 47 cm. The object of the article is to apply various methods of lithic analysis, including edge-wear analysis and experiment, to explain this variation. In examini
