“…Common reed (Phragmites australis), a prominent herbaceous species, emerges as a candidate for bioenergy production because of its robust growth kinetics, high biomass productivity, and notable resilience to a spectrum of environmental stress factors [16]. Recently, some pretreatment methods, such as H 2 SO 4 -or NaOH-assisted choline chloride (ChCl)/glycerol DES pretreatment [17,18], microwaveassisted ChCl/p-toluene sulfonic acid DES pretreatment [19], and ammonia/sodium sul te pretreatment [20], have been explored to increase the enzymatic hydrolysis yield of ~ 85-88%. However, the use of inorganic alkaline reagent has corrosive to pretreatment equipment, and the cost of DES is relative higher.…”

Producing fermentable sugars from lignocellulosic biomass could provide renewable substrate for biofuel production by microbial fermentation. However, the structure of lignocellulose hinders enzymatic saccharification efficiency to obtain sugars, thus development of efficient pretreatment methods to reduce the biomass recalcitrance is an important issue. In this study, the effects of two typical processes including hydrothermal (HTP) and citric acid pretreatments (CAP) on the enzymatic hydrolysis yield of reed biomass were investigated. The results indicate that a higher glucose yield of 87.1% was achieved using cellulase of 10 FPU/g substrate following HTP conducted at 180 ℃ for 120 min. Subsequently, a yield of 63.4% glucose was realized after enzymatic hydrolysis with cellulase when subjected to reed pretreatment with 6% (w/v) CA at 150 ℃ for 60 min. The enhancement in enzymatic yield to 84.2% was also achieved by adding Tween-80 of 100 mg/g substrate. The mechanism of enhanced enzymatic hydrolysis by HTP and CAP processes was elucidated through physicochemical characterization techniques. Overall, this study offers valuable insights for the production of fermentable sugars from renewable lignocellulose.

BACKGROUNDThe potential for the efficient conversion of lignocellulosic biomass has been extensively explored to produce a wide range of bioproducts. Many approaches have been sought for the deep conversion of lignin to generate products that are toxin‐free and beneficial for processing into high‐value‐added components.RESULTSThis study reported a fungus isolated from the deep sea with strong synthesis of multiple lignocellulases, conversion of lignin and guaiacol (0.1%) by 71.6% and 86.1% within 9 days at 30 °C respectively, and outstanding environmental adaptability (20–50 °C and pH 3–8). Metabolic pathway profiling showed that this fungus utilized lignin to rapidly activate multiple ring‐opening reactions including the 2,3‐ and 3,4‐cleavage pathways, with the 2,3‐cleavage pathway predominating after 5 days. Conversion of metabolic intermediates confirmed the superb potential of this strain for lignin treatment. Meanwhile, its shikimic acid pathway was metabolically active under lignin.CONCLUSIONThis further expands the potential to produce valuable bioproducts during lignin treatment, especially under ambient conditions, which can significantly enhance high‐value precursor compound production. © 2024 Society of Chemical Industry.
