“…When treatment time was at 60 min, the highest yield and the concentration of reducing sugars were 26.7% and 66.7 g/L, increasing by 80.0 and 74.6%, respectively, compared with those at 15 min. Enough pretreatment time is required for allowing more small cellulose fibers exposed on the pretreated surface of JAS, which may improve the hydrolysis of cellulose [ 26 , 27 ]. On the other hand, the increase in treatment time leads to lignin degradation in the severe conditions [ 28 ].…”

BackgroundButanol as an important chemical and potential fuel could be produced via ABE fermentation from lignocellulosic biomass. The use of food-related feedstocks such as maize and sugar cane may not be a sustainable solution to world’s energy needs. Recently, Jerusalem artichoke tubers containing inulin have been used as feedstock for butanol production, but this bioprocess is not commercially feasible due to the great value of inulin as functional food. Till now, there is a gap on the utilization of Jerusalem artichoke stalk (JAS) as feedstock for microbial butanol production.ResultsBiobutanol production from JAS was investigated in order to improve cellulose digestibility and efficient biobutanol fermentation. Compared with 9.0 g/L butanol (14.7 g/L ABE) production by 2% NaOH pretreatment of JAS, 11.8 g/L butanol (17.6 g/L ABE) was produced in the best scenario conditions of NaOH–H2O2 pretreatment, washing times and citrate buffer strengths etc. Furthermore, more than >64% water in washing pretreated JAS process could be saved, with improving butanol production by >25.0%. To mimic in situ product recovery for ABE fermentation, the vapor stripping–vapor permeation (VSVP) process steadily produced 323.4–348.7 g/L butanol (542.7–594.0 g/L ABE) in condensate, which showed more potentials than pervaporation for butanol recovery.ConclusionsTherefore, the present study demonstrated an effective strategy on efficient biobutanol production using lignocellulosic biomass. The process optimization could contribute to significant reduction of wastewater emission and the improvement of lignocellulosic biomass digestibility and biobutanol production, which makes biobutanol production more efficient using JAS.

“…On the other hand, the impurities in the raw biomass, in particular calcium cations, poisoned the active tungsten species possibly by forming insoluble calcium tungstate [24]. Therefore, both lignin and poisoning impurities have to be removed prior to the catalytic reaction, for which various pretreatment technologies have been explored [10,[27][28][29][30]. Interestingly, a recent work by Miao et al showed that microalgae (Chlorococcum sp.)…”

“…Finally, the decomposition of sulfolene into sulfur dioxide (see above) has also been applied in a more biological context to decompose the lignocellulosic network of a biofuel crop. [36] The full biological results are outside the scope of this review but are discussed in a recent review [16] and the original reports.…”

The Development and Application of Sulfur Dioxide Surrogates in Synthetic Organic Chemistry

Sulfur dioxide has a rich and varied chemistry that can be traced back to the early 1900s. Despite the potential utility of sulfur dioxide based reactions, delivering products such as sulfones, sulfonamides and sulfinic acids, the number of examples of these reactions being exploited in synthesis is arguably lower than would be expected. One significant contributing factor to this is undoubtedly the toxic and gaseous nature of SO2. One strategy to overcome this limitation is to employ an equivalent, or surrogate, so that the gaseous reagent is no longer needed. This strategy has proven to be a success, with a number of methods being described. The reactions reported include variants of traditional reactions in which the gaseous reagent has been replaced with a surrogate, and also new transformations for which no gaseous reaction is known. This Focus Review discusses the origin of sulfur dioxide surrogates and then considers their application to synthetic organic chemistry.
