Summary: This work focused on the production of cellulosic ethanol from sugarcane bagasse in a pilot scale unit by applying current bioprocessing strategies, with the aim of recovering and characterizing the end products. The fermentation resulted in a reproducible performance, with a yield of 0.49 g/g, productivity of 6.96 g/(L·h), and cell viability of 95.3%. However, the distilled fractions showed higher content of higher alcohols and sulfur than the standard specification for ethanol fuel.

Summary: Potassium impregnation enhances the thermal decomposition and reactions of biomass. This study investigated the addition of potassium carbonate (K2CO3) to sugarcane bagasse (SCB) and found that it significantly affects the cellulose structure and thermal decomposition temperature of SCB. The optimal conditions for K2CO3 pretreatment were determined using response surface methodology (RSM), resulting in improved torrefaction of SCB for biomass power plant applications.

Summary: This study investigates the high gravity fed-batch simultaneous saccharification and fermentation (FB-SSF) of sequentially pretreated sugarcane bagasse (SCB) for enhanced bioethanol production, using the inhibitor tolerant Kluyveromyces marxianus JKH5 C60. The optimized lab-scale FB-SSF, with intermittent feeding of SCB and enzyme, resulted in maximum ethanol titer, efficiency, and productivities of 73.4 g/L, 78%, and 3.0 g/L/h, respectively, after 72 h in the presence of inhibitors. Additionally, fermentation of pentose rich dilute acid hydrolysate of SCB by Pichia stipitis NCIM 3499 yielded an ethanol titer of 6.8 g/L. The overall ethanol yield during the developed process was 260.1 g/kg native SCB, indicating the industrial potential of this bioethanol conversion process.

Summary: High energy consumption is a major obstacle for the conversion of lignocellulose into biofuels and biochemicals. In this study, a self-designed pilot-scale device with recycling of black liquor and waste washing water was used for low-temperature pretreatment and high-solid enzymatic hydrolysis of sugarcane bagasse. The results showed that the enzymatic hydrolysis of the treated sugarcane bagasse achieved a high glucose concentration and glucan conversion. A low-energy strategy for cellulosic ethanol production with low emission was proposed.

Summary: A new one-pot synthesis method optimized by a 2(3) experimental design was developed to prepare a biosorbent SBSPy, which showed efficient removal of Cu(II) and Zn(II) from single-component aqueous solutions. The bi-functionalization of the biosorbent improved its selectivity, with different functional groups favoring the adsorption of Cu(II) and Zn(II) respectively. Batch and continuous modes were used for the removal process, and the biosorbent showed potential for water treatment in fixed-bed column adsorption.

Summary: H-1 time domain nuclear magnetic resonance (H-1 TD-NMR) at a low magnetic field is a powerful technique for characterizing the structure and dynamics of soft organic materials. The sensitivity to H-1-H-1 magnetic dipolar couplings allows for real-time monitoring of processes affecting molecular mobility. Different dipolar echo methods are evaluated for probing polymerization reactions, with good agreement in results and the Dipolar Filtered Magic Sandwich Echo (DF-MSE) method showing advantages for data handling and processing.

Summary: Supercritical impregnation (SFI) can be used to load polyphenols into corn starch aerogels, creating new delivery systems for the food industry. This study examined the effects of SFI pressure and temperature on the loading of polyphenols from passion fruit bagasse into corn starch aerogels. The best SFI condition for total phenolics and antioxidant capacity was found to be 65 degrees C/37.5 MPa. The efficiency of SFI was confirmed by the decrease in aerogel surface area, volume, and particle diameter.
