“…The demand of materials from renewable resources which can replace oil based chemicals and fuels is increasing lately because of the progressive depletion of natural resources, instability of oil prices and environmental impact caused by pollution [1] [2]. Several developing and developed countries are investing in the development of products renewable and sustainable, which do not cause harm to the environment, based mainly on lignocellulosic biomass [3] [4].…”

Brazil is the world largest producer of sugarcane (Saccharum officinarum) leading to a great generation of residues such as bagasse and straw, which represent two thirds of sugarcane energetic potential. Regarding these residues energetic potential, it is interesting to study their application in biorefinery processes. Thus, this work aimed at performing a chemical characterization of sugarcane straw and bagasse from RB867515 cultivar grown in Rio Grande do Sul-Brazil aiming at their use as feedstock in biorefinery processes. The obtained results were compared to data from other states and it was possible to conclude that edaphoclimatic conditions of Rio Grande do Sul have little influence in sugarcane residues chemical composition. Sugarcane bagasse presents larger potential for energetic use because of its volatiles content (74.82%) slightly higher than straw (68.90%), besides its high lignin content (21.85%) and higher calorific value (18.70 MJ/kg). Both sugarcane residues produced in Rio Grande do Sul have potential use as substrate in the obtainment of high value-added products from their cellulosic fractions (41.30% and 37.25%, respectively). The evaluation of energetic and chemical potential of sugarcane bagasse and straw produced in Rio Grande do Sul leads to the conclusion that these materials have high potential for use as feedstock in biorefineries.

“…In fact, attempts to remove pathogenicity factors of K. pneumoniae are being addressed [27]. Another recent report described the conversion of glycerol to 2,3-BD with Serratia sp., with a yield of 0.43 (w w −1 ) [28] and 0.42 (w w −1 ) by a genetically modified Raoultella ornithinolytica strain and glycerol [17]. However, unsurpassed yields of 0.50 (w w −1 ) were achieved with the mutants obtained in this work.…”

“…All intersections between parameters are assumed negligible. The assayed parameters were: initial glycerol concentration (60, 75, 90 g L −1 ), CoCl 2 concentration (0.012, 0.024, 0.036 g L −1 ), and temperature (28,30, 33 • C). The oxygen saturation was kept fixed at 5% with 500 rpm of agitation.…”

Improved Raoultella planticola Strains for the Production of 2,3-Butanediol from Glycerol

Raw glycerol is an industrial byproduct from biodiesel production and is one of the most promising substrates for 2,3-butanediol (2,3-BD) production; however, 2,3-BD is not yet produced by fermentation from glycerol on a commercial scale due to poor process economics. Class 1 microorganism collections were screened and Raoultella planticola strain CECT 843 proved to be the best 2,3-BD producer, achieving (23.3 ± 1.4) g 2,3-BD per L and a yield of 36% (g 2,3-BD per g glycerol). To further increase product concentration and yield, R. planticola CEC T843 was subjected to random mutagenesis using ultra-violet (UV) light and ethyl methane sulfonate (EMS). Two mutant strains were found to produce at least 30% more 2,3-BD than the wild type: R. planticola IA1 [(30.8 ± 3.9) g 2,3-BD per L and 49% yield] and R. planticola IIIA3 [(30.5 ± 0.4) g 2,3-BD per L and 49% yield].

“…Due to the ever-growing demand for energy, environmental impact caused by pollution, and the depletion of fossil fuel reserves, the demand for materials from renewable resources has become an important matter [1,2]. Lignocellulose biomass is considered one of replacing chemicals as well as fuels based on oil [3].…”

Separation of cellulose from agricultural straw is one of the key bottlenecks hindering the application of such kind of biomass resources. In this chapter, we provide three environmental-friendly ways for separation of cellulose from agricultural straw pretreated with steam explosion, which include delignification with recyclable water-polar aprotic organic solvent, selective bio-degradation of the lignin component, and extraction of cellulose with imidazolium-based ionic liquids from the steam-exploded rice straw. The isolated rice straw celluloses have been adopted as an enhancement for all-cellulose composites (ACCs) and cellulose/cement composites. Ultra-high tensile strength (650.2 MPa) can be achieved for the ACCs containing the activated straw cellulose fiber (A-SCF). The cellulose/cement composites show a significant promotion in the flexural strength and fracture toughness. The new nonderivative solvent for cellulose, tetrabutylammonium hydroxide (TBAH) aqueous solution with urea as additives has been proved to be manipulable for dissolving cellulose.
