Ethanol production from steam pretreated sugarcane bagasse via simultaneous saccharification and fermentation (SSF) using cellulase and b.glucosidase enzymes

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

Processing Lignocellulosic Biomass into Ethanol - Implications of High Solid Loadings

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

Lithic Technological Analysis of the Thin-butted Flint Axe

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

On Speciation in Birds – Genomic Signatures across Space and Time

Popular Abstract in Swedish Ända sedan Charles Darwin 1859 publicerade Om arternas uppkomst har just frågan om hur en art delas i två varit en central del av evolutionsbiologin. Darwin hade under resorna på HMS Beagle iakttagit hur bland annat härmtrastar och finkar på Galápagos varierade mellan öarna och drog slutsatsen att flera närbesläktade arter inom grupperna delade samma ursprung. Darwin beThe process of speciation is a cornerstone in evolutionary biology. In Darwin’s On the Origin of Species, he described how he imagined that a new species would evolve to fill an empty niche. This focus on ecology shifted with Mayr towards the importance of isolation, and for many decades the geographic modes of speciation were debated. Speciation in sympatry, i.e. without any isolation between the
