“…Sweet sorghum [ Sorghum bicolor (L.) Moench], an annual C 4 plant belonging to Poaceae, is a natural variation of grain sorghum [ 5 ]. This species is characterized by high fermentable sugars in the juice of the stalks, which makes it attractive as a valuable bioenergy crop [ 6 , 7 ]. Meanwhile, sweet sorghum has been widely used as a forage due to its high biomass and growth rate, as well as prominent palatability and digestibility [ 8 ].…”

Sweet sorghum is an important bioenergy grass and valuable forage with a strong adaptability to saline environments. However, little is known about the mechanisms of sweet sorghum coping with ion toxicity under salt stresses. Here, we first evaluated the salt tolerance of a sweet sorghum cultivar “Lvjuren” and determined its ion accumulation traits under NaCl treatments; then, we explored key genes involved in Na+, Cl−, K+ and NO3− transport using transcriptome profiling and the qRT-PCR method. The results showed that growth and photosynthesis of sweet sorghum were unaffected by 50 and 100 mM NaCl treatments, indicative of a strong salt tolerance of this species. Under NaCl treatments, sweet sorghum could efficiently exclude Na+ from shoots and accumulate Cl− in leaf sheaths to avoid their overaccumulation in leaf blades; meanwhile, it possessed a prominent ability to sustain NO3− homeostasis in leaf blades. Transcriptome profiling identified several differentially expressed genes associated with Na+, Cl−, K+ and NO3− transport in roots, leaf sheaths and leaf blades after 200 mM NaCl treatment for 6 and 48 h. Moreover, transcriptome data and qRT-PCR results indicated that HKT1;5, CLCc and NPF7.3-1 should be key genes involved in Na+ retention in roots, Cl− accumulation in leaf sheaths and maintenance of NO3− homeostasis in leaf blades, respectively. Many TFs were also identified after NaCl treatment, which should play important regulatory roles in salt tolerance of sweet sorghum. In addition, GO analysis identified candidate genes involved in maintaining membrane stability and photosynthetic capacity under salt stresses. This work lays a preliminary foundation for clarifying the molecular basis underlying the adaptation of sweet sorghum to adverse environments.

“…On the other hand, the agave bagasse is an important residual biomass of the tequila alcoholic beverage industry in Mexico, and about of 40% of the total Agave Tequilana Weber blue variety is bagasse. In addition, the chemical composition composed of cellulose, hemicellulose, and lignin makes this biomass a promising raw material in the development of second-generation biorefineries [18][19][20][21][22][23][24]. Additionally, hot compressed water pretreatment is an important hydrothermal process where the water is pressurized in the liquid and vapor phase due to the thermodynamic equilibrium, causing an autoionization of the water and the production of acetic acid from the hemicellulosic fraction, both acting as catalysts in the process and fractionating the biomass in a liquid phase of hemicellulosic fraction and a solid fraction rich in cellulose and lignin [25][26][27][28][29].…”

Agave bagasse is a residual biomass in the production of the alcoholic beverage tequila, and therefore, it is a promising raw material in the development of biorefineries using hot compressed water pretreatment (hydrothermal processing). Surfactants application has been frequently reported as an alternative to enhance monomeric sugars production efficiency and as a possibility to reduce the enzyme loading required. Nevertheless, the surfactant’s action mechanisms in the enzymatic hydrolysis is still not elucidated. In this work, hot compressed water pretreatment was applied on agave bagasse for biomass fractionation at 194 °C in isothermal regime for 30 min, and the effect of non-ionic surfactants (Tween 20, Tween 80, Span 80, and Polyethylene glycol (PEG 400)) was studied as a potential enhancer of enzymatic saccharification of hydrothermally pretreated solids of agave bagasse (AGB). It was found that non-ionic surfactants show an improvement in the conversion yield of cellulose to glucose (100%) and production of glucose (79.76 g/L) at 15 FPU/g glucan, the highest enhancement obtained being 7% regarding the control (no surfactant addition), using PEG 400 as an additive. The use of surfactants allows improving the production of fermentable sugars for the development of second-generation biorefineries.
