“…This was in agreement with a study by Masset et al (2010), in which the biogases produced during the first 8 d of anaerobic digestion of sugar (such as glucose) were mainly H 2 and CO 2 . The gas generation rates from all of the MPs were initially high and then gradually declined in our study.…”

Significance statement: In this original paper, we present the biochemical composition and potential methane production from the anaerobic digestion of each type of lignocellulosic waste from a banana cultivar (Williams Cavendish: triploid Musa AAA group). These wastes are usually abandoned in the plantation after the fruits have been harvested. There is great interest in obtaining energy from this generally neglected biomaterial, particularly in the contexts of global warming and sustainable development. 2Abstract: We studied banana lignocellulosic biomass (BALICEBIOM) that is abandoned after fruit harvesting, and assessed its biochemical methane potential, because of its potential as an energy source. We monitored biogas production from six morphological parts (MPs) of the "Williams Cavendish" banana cultivar using a modified operating procedure (KOP) using KOH. Volatile fatty acid (VFA) production was measured using high performance liquid chromatography. The bulbs, leaf sheaths, petioles-midribs, leaf blades, rachis stems, and floral stalks gave total biogas production of 256, 205, 198, 126, 253, and 221 mL g −1 dry matter, respectively, and total biomethane production of 150, 141, 127, 98, 162, and 144 mL g −1 , respectively. The biogas production rates and yields depended on the biochemical composition of the BALICEBIOM and the ability of anaerobic microbes to access fermentable substrates. There were no significant differences between the biogas analysis results produced using KOP and gas chromatography. Acetate was the major VFA in all the MP sample culture media.The bioconversion yields for each MP were below 50%, showing that these substrates were not fully biodegraded after 188 d.The estimated electricity that could be produced from biogas combustion after fermenting all of the BALICEBIOM produced annually by the Cameroon Development Corporation-Del Monte plantations for 188 d is approximately 10.5×10 6 kW h (which would be worth 0.80-1.58 million euros in the current market). This bioenergy could serve the requirements of about 42000 people in the region, although CH 4 productivity could be improved.

“…A first batch sequence at uncontrolled-pH decreasing from 7.3 down to 5.2 was achieved for cell enrichment. It was followed by a second sequence with pH control at 5.2 after removal/addition of fresh culture medium (40% of the initial 2.3 L volume as described elsewhere; [34]). Bioreactors preparation, start-up and sequential operation along with samples collection were already detailed elsewhere [34].…”

Fermentative hydrogen production has often been described as inhibited by its own gas production. In this work, hydrogen production by Clostridium butyricum was investigated in batch Biochemical Hydrogen Potential (BHP) tests and in a 2.5 L Anaerobic Sequenced Batch Reactor (AnSBR) under different operating conditions regarding liquid-to-gas mass transfer.Through the addition of both stirring up to 400 RPM and nitrogen sparging, the yields were enhanced from 1.6 to 3.1 mol H2 ·mol glucose -1 and the maximum hydrogen production rates from 140 to 278 mL·h -1 . These original results were achieved with a pure Clostridium strain. They showed that hydrogen production was improved by a higher liquid-to-gas hydrogen transfer resulting in a lower dissolved hydrogen concentration in the culture medium and therefore in a lower bacterial inhibition. In addition, biohydrogen partitioning between the gas and the liquid phase did not conform to Henry's Law due to critical supersaturation phenomena up to seven-fold higher than the equilibrium conditions. Therefore dissolved hydrogen concentration should be systematically measured instead of the headspace hydrogen partial pressure. A model was proposed to correlate H 2 production yield and rate by the pure C.butyricum strain CWBI1009 with mass transfer coefficient K L a.

Hydrogen fuel is a promising alternative to fossil fuels because of its energy content, clean nature, and fuel efficiency. However, it is not readily available. Most current producion processes are very energy intensive and emit carbon dioxide. Therefore, this article reviews technological options for hydrogen production that are eco‐friendly and generate clean hydrogen fuel. Biological methods, such different fermentation processes and photolysis are discussed together with the required substrates and the process efficiency.
