“…Thermochemical treatment of biomass feedstock, and gasification in particular, is gaining strong traction in Europe giving the numerous opportunities associated to product flexibility and low environmental impact. Recent studies have proven that Bio-H2 offers the largest potential in terms of GHG removal (Chai et al, 2021;Inayat et al, 2020;Tian et al, 2019). However, Bio-H2 production should ideally rely on the use of second or third generation biomass as primary feedstock to avoid land use competition with food crops and intensification of deforestation, habitat loss and loss of soil fertility (Mohr and Raman, 2015).…”

“…Biohydrogen generation by photosynthetic bacteria, such as PNSB, exhibits low productivity making them unsuitable to generate H 2 for large-scale applications ( Chandrasekhar et al, 2015 ). However, their production has been insufficiently explored, being underdeveloped, and remains a promising renewable source of H 2 considering the energy input (sunlight) and purity of product output ( Gupta et al, 2013 ; Chandrasekhar et al, 2015 ; Jiménez-Llanos et al, 2020 ; Chai et al, 2021 ). Several strategies to enhance photo-fermentative biohydrogen production have been described, such as immobilization of bacteria for continuous H 2 production ( Fiβler et al, 1995 ; Elkahlout et al, 2019 ), modification of carbon substrates, nitrogen source, and micronutrients contained in the H 2 production medium ( Liu et al, 2009 ; Laocharoen and Reungsang, 2014 ; Chen et al, 2017 ), and genetic modifications ( Barahona et al, 2016 ; Feng et al, 2018b ; Ma et al, 2021 ), among others.…”

Nitrogenase-dependent H2 production by photosynthetic bacteria, such as Rhodobacter capsulatus, has been extensively investigated. An important limitation to increase H2 production using genetic manipulation is the scarcity of high-throughput screening methods to detect possible overproducing mutants. Previously, we engineered R. capsulatus strains that emitted fluorescence in response to H2 and used them to identify mutations in the nitrogenase Fe protein leading to H2 overproduction. Here, we used ultraviolet light to induce random mutations in the genome of the engineered H2-sensing strain, and fluorescent-activated cell sorting to detect and isolate the H2-overproducing cells from libraries containing 5 × 105 mutants. Three rounds of mutagenesis and strain selection gradually increased H2 production up to 3-fold. The whole genomes of five H2 overproducing strains were sequenced and compared to that of the parental sensor strain to determine the basis for H2 overproduction. No mutations were present in well-characterized functions related to nitrogen fixation, except for the transcriptional activator nifA2. However, several mutations mapped to energy-generating systems and to carbon metabolism-related functions, which could feed reducing power or ATP to nitrogenase. Time-course experiments of nitrogenase depression in batch cultures exposed mismatches between nitrogenase protein levels and their H2 and ethylene production activities that suggested energy limitation. Consistently, cultivating in a chemostat produced up to 19-fold more H2 than the corresponding batch cultures, revealing the potential of selected H2 overproducing strains.

“…Biomass gasification would be an appropriate alternative solution for managing such large amount of aquatic plant biomass and help to eradicate the excessive amount of water hyacinth present in the ecosystem. Meanwhile, such initiative could also facilitate the paradigm shift to alternative renewable energy sources and possibly reducing the heavy reliance on the dwindling supply fossil fuels for most industrial activities [3,4,5,6,7,8,9,10,11]. Utilization of conventional fossil fuel resources often times contribute a huge share to the net greenhouse gas emission.…”

Abstract. Water hyacinth being one of the top invasive aquatic plants has brought upon various challenges towards the humanity and the environment. The magnitude of the menace of uncontrollable growth and spread of water hyacinth has sparked the interest of researchers in identifying its potential as a biomass feedstock for biofuel production. Biomass gasification is deemed as a promising green technology which is capable of converting biomass into value-added commodity. Conversion of such large quantity of biomass into biofuel via gasification does not only help to promote sustainable resource utilization but also facilitates the reduction of global carbon impacts and engender socioeconomic development. The addition of catalysts to the gasification process could enhance the formation of gaseous products where the gas composition may be altered. This study aims to present the preliminary study on the gasification performance of water hyacinth biomass in a lab scale fixed-bed downdraft gasifier (67 mm diameter and 750 mm height), with the use of air as the gasifying agent in a batch feeding of 50 grams for each run. The results showed that temperature has a substantial effect on the gasification of water hyacinth whereby hydrogen produced was raised from 2.92 vol.% to 11.19 vol.%. Further gasification tests are expected for the optimization of the main process parameters such as biomass particle size and catalyst loading.
