“…It was discovered that the marginal increase in sugar recovered was not worth the economic implication of increasing the residence time above 30 min. Similar results were also reported in the hydrolysis of moso bamboo residues [12,46]. To further the dilute acid hydrolysis investigation, the impact of Solid Loading Ratio (SLR) was investigated as it was reported to be an important factor to determine the concentrations of released sugars [47,48].…”

The potential of using sorghum milling waste for the development of a biorefining strategy for the production of bioethanol was investigated. Both red and white sorghum were processed using a traditional Nigerian wet-milling process to sorghum flour. The sorghum milling waste, sorghum bran, was hydrolysed using both enzymatic and dilute acid hydrolysis to produce a generable fermentation feedstock. The hydrolysates were subsequently investigated for fermentative biofuel production. Following a hydrolysis step, a medium containing ~ 61 g/L glucose was obtained. Trace presence of inhibitors was detected in the hydrolysates and sufficient nitrogen content to support microorganism growth and bioethanol production. In test bioethanol production experiments using the sorghum milling waste derived hydrolysates only, 24.35 g/L bioethanol was produced by a yeast Kluyveromyces marxianus, equivalent to a yield of 0.15 gram bioethanol per gram of sorghum milling waste.

“…Alkaline hemicellulose extraction processes on lignocellulosic materials are also considered an effective pretreatment for enzymatic hydrolysis to make sugars and bioethanol. 22,23 Alkali pretreatments can cause the solubilization of hemicellulose and lignin and modifications in the crystalline state of the cellulose. 22 These effects can increase the internal surface of cellulose, decrease the degree of polymerization and crystallinity, and make the cellulose more accessible for enzymes.…”

Hemicellulose is a polymer found abundantly in lignocellulosic feedstocks, with many potential market applications. However, there has yet to be a large‐scale commercial process to isolate hemicellulose from lignocellulosic biomass. A techno‐economic assessment for hemicellulose extraction from sugarcane bagasse, switchgrass, and poplar was made. Two isolation processes after alkaline extraction were considered: (1) producing total hemicellulose and (2) producing hemicellulose A (water‐insoluble fraction) only. In a greenfield scenario, a byproduct of the process is sugar, whereas in a co‐location scenario the biomass after hemicellulose extraction is returned to the pulp mill for its fiber value. Operating costs, capital investment, minimum hemicellulose selling price (MHSP), the effect of input material and product prices along with several other process parameters on the MHSP were determined for each scenario. Co‐location scenarios had a dramatically lower capital cost and MHSP relative to greenfield scenarios. This was due to co‐location scenarios utilizing existing biomass processing and utilities equipment and not requiring a sugar‐production process. Among the three biomasses, hemicellulose extraction from sugarcane bagasse had the lowest MHSP for all scenarios, mainly due to a higher hemicellulose extraction yield. Extraction of hemicellulose A from sugarcane bagasse in a co‐location scenario had a low capital cost of 56 million USD and had a reasonable MHSP of 274 USD/t (metric ton). This research indicates that there is reasonable economic potential for hemicellulose extraction from lignocellulosic biomass for applications to replace starch or as a starting material for the production of xylo‐oligomeric prebiotics. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd

“…Bamboo is a useful plant which is widely distributed in both temperate and tropical regions of the world and offers a rich yield of bamboo shoots [20]. The eighth national forest resources inventory results shows that Moso bamboo covers an area of 4.43 million hm 2 in China, which provides abundant Moso bamboo shoots [21][22][23]. Bamboo shoots are well known as an excellent health food with dietary fiber, proteins, amino acids, carbohydrates, and minerals [24].…”

A novel fluorescent composition was firstly isolated from natural winter fresh Moso bamboo shoots, and its optical properties were fully investigated by fluorescence spectroscopy. It could emit strong blue light both in solid and solution state, providing high fluorescence intensity in ethanol. The solution's concentration and addition of water greatly affected the fluorescence intensity, high concentration and addition of much water could quench fluorescence. Apoptosis results showed that the fluorescent extract (0-25 mg/L) could not induce apoptosis of Hela cells. Confocal fluorescent microscopic imaging in human hepatocellular carcinoma cells (HepG2) was realized using the fluorescent extract, it could dye the whole cell well which was different from 4', 6-diamidino-2-phenylindole (DAPI) only dying cell nucleus. The fluorescent extract may be candidate for future natural fluorescent bio-imaging agent.
