The effect of temperature (37 and 55 °C) inoculum-to-substrate ratios (ISRs) on biohydrogen (first-stage ISRs 0.25, 0.5, 1) methane (second-stage 2, 4, 6) production during two-stage anaerobic digestion molasses using mixed consortia was investigated. At 37 °C, 1 4 produced the highest yields (63.61 NL-H2/kg-VSadded) (VS: volatile solid) (1092.70 NL-CH4/kg-VSadded). ISR 0.5 yielded 25.03 NL-H2/kg-VSadded, while 806.54 NL-CH4/kg-VSadded. Firmicutes, specifically Clostridia, dominated first stage at both temperatures. second (ISR 4) °C included 16.06% Chloroflexi 22.84% it 7.55% Thermotogota.

The study aimed to evaluate the genetic diversity of 41 sweet sorghum genotypes from seven countries for key biofuel-related traits over two growing seasons (2020 and 2021) in a semi-arid Mediterranean environment. Genotypes were assessed bioethanol production such as fresh stalk yield (FSY), juice (JY), Brix, dry biomass (DBY), theoretical ethanol (JEY), lignocellulosic (LEY), total (TEY), well their potential solid biofuel production, measured through bagasse ash, nitrogen, moisture content. Significant variations observed among across most traits, analyzed using analysis variance, principal component analysis, hierarchical cluster identifying DBY, LEY, TEY primary contributors overall variation. Cluster grouped into five distinct clusters, highlighting traits. correlation revealed significant positive relationships between FSY, TEY, indicating that higher directly enhances output. Strong correlations FSY underscore importance maximizing production. However, like ash nitrogen contents, which negatively correlated with JEY, present challenges improving combustion quality. concludes certain genotypes, particularly ‘Yellow Bonnet’ ‘IS 3556’, exhibited strong climates where water scarcity high temperature favor sugar yields. These demonstrated JEYs, LEYs, TEYs, suggesting adaptability unique environmental stresses this region, making them good candidates sustainable similar climates.

The effect of increasing organic load on the specific methane yields (SMYs) and kinetics production during anaerobic digestion (AD) sugarcane bagasse (SB) was investigated in batch experiments at 37 °C. AD system increased based an increase feed-to-inoculum (F/I) ratio (T1–T5) Total Solids (TS)% working volume (T6–T10). results show that both treatment sets, led to a decrease SMY. Higher loads terms F/I (T4 T5) were inhibited due Volatile Fatty Acid (VFA) accumulation. On other hand, higher (T8, T9 T10) TS% by accumulation NH4-N. Thus, 50 gVS/L = 1.0 TS 10% (T3) found be highest had no significant inhibitions among tested treatments. from kinetic studies first-order model is best fit for SMY data, with average differences% 2.32% 3.13% treatments T1–T5 T6–T10, respectively.
