Hydrogen production from mushroom farm waste with a two-step acid hydrolysis process

Biohydrogen production from xylose by Thermoanaerobacterium thermosaccharolyticum KKU19 isolated from hot spring sediment

“…Recent research has considered using lignocellulosic materials as potential feedstock for bioenergy production because they are in abundance and locally available [10,11]. Sugars that are obtained in the hydrolysate after the hydrolysis pretreatment of lignocellulosic materials are hexose (glucose) and pentose (xylose and trace amounts of arabinose).…”

Techno-economic evaluation of biohydrogen production from wastewater and agricultural waste

“…Mushroom farm waste, mainly spent mushroom substrate, rich in cellulose and also an efficient biohydrogen resource, which was collected from a mushroom farm in Shinshou, Taichung County. The spent mushroom substrate was composed of 55.29% cellulose and hemicellulose; 16.54% lignin and 28.17% of other components [28]. The amount of agricultural waste was 4 million tons/year.…”

“…The feedstock of agricultural waste was pretreated with a two-step acid hydrolysis process using sulfuric acid (55%) to degrade cellulose at a temperature of 40 C for 20 min in the first-step and then hydrolyzed with sulfuric acid (5.9%) for 20 min in the second-step. The data obtained in a batch reactor with a working volume of 50 mL, using the hydrolysate from the two-step hydrolysis process, obtained a hydrogen production rate of 4.38 L/d/L [28].…”

Optimizing biohydrogen production from mushroom cultivation waste using anaerobic mixed cultures

“…Therefore, proper treatment or usage of this waste could avoid the environmental problems. Moreover, recent studies show that this waste could be a feedstock for biohydrogen production in effective way [11]. The advantages of using MCW feedstock for hydrogen production include cost effective because of this waste being needed to be treated for reducing environmental pollution problems.…”

“…Several types of inoculum have been reported such as sewage sludge [9] and cow dung [10]. Pretreatment of the mushroom cultivation waste by using acid was also studied [11].…”
