“…After glucose consumption leveled off at 12 hours of the fermentation, both ethanol production and xylose consumption were stopped. This result suggests that K. marxianus might require the existence of glucose to metabolize xylose to produce ethanol, which is consistent with the observations from the literature reports (Signori et al 2014;Du et al 2019). Meanwhile, the data also demonstrate that a good amount of 9 g/L of xylose was consumed from 6 to 12 hours once glucose reached a low level of 3.3 g/L at 6 hours, which provides a potential strategy to apply K. marxianus to utilize xylose rich biomass for high-e ciency ethanol production.…”

Quercus infectoria is one of the most abundant native oak species in the Kurdistan region of Iraq. This study focused on utilizing leaves of Quercus infectoria for ethanol production in the region. A typical three-step conversion process of acid pretreatment, enzymatic hydrolysis, and yeast fermentation was investigated to produce ethanol from the leaves. Under the selected acid pretreatment and enzymatic hydrolysis conditions, the glucose and xylose concentrations in the hydrolysates reached 11.4 g/L and 16.8 g/L, respectively, with the corresponding sugar conversions of 42.8% and 99.8%. A yeast strain, Kluyveromyces marxianus, was used to ferment mono-sugars in the hydrolysates for ethanol production. The ethanol production rate and conversion of K. marxianus in the fermentation were 0.17 g/L/h and 27%. The techno-economic analysis further concluded that a regional ethanol biorefinery can be established in the Zawita sub-district, Iraq to utilize Q. infectoria leaves to produce 200,000,000 kg ethanol/year with a positive energy balance of 745,052,623 MJ/year. The net annual revenue of the biorefinery is $123,692,804. The payback period of the biorefinery is 10 years.

“…Entretanto, a literatura demonstra que essa concentração do ácido é maior do que a presente normalmente nos hidrolisados (Fonseca et al, 2011). É importante destacar também que esse nível de tolerância é similar ao que Du et al (2019) observaram recentemente para a levedura Spathaspora passalidarum, espécie também encontrada na Mata Atlântica (Cadete e Rosa, 2018). Cabe ressaltar ainda que, nos meios com xilose, na ausência do inibidor e com 0,6 g L -1 desse ácido, a levedura obteve maior crescimento do que em meios com glicose.…”

Agricultural sector has inescapably drawn attention towards itself due to growing concern over population explosion, changing climate and depletion of resources. Advancements in technology have caused rapid boost in farm productivity and hence huge production of agro-wastes. There have been massive deteriorating impacts of agro-wastes on existing environmental conditions, creating wide scale environmental pollution as well as biodiversity loss. Since, agro-wastes have huge potential in the form of energy and nutrient recovery (ENR), amalgamations of different technologies would promote sustainability. ENR not only adjoins an added profitable product but also facilitates to close environmental nutrient cycles. This provides a substitute to existing unsustainable approaches that are energy demanding and reliant on nonrenewable sources of energy. This review underpins why ENR from agro-waste must be key concern in production of array of higher value products.
