“…The process followed for biohydrogen production was simultaneous saccharification and fermentation. Oceguera-Contreras et al [63] produced biohydrogen with a yield of 1246.36, 1571.81, and 232.72 mL H 2 /L from the bagasse, molasses, and vinasses agro-industry wastes when vermihumus-associated microorganisms as inoculum were used as a source and found that these microbes not only produce biohydrogen but also help in the degradation of lignocellulosic waste material.…”

More than 80% of the energy from fossil fuels is utilized in homes and industries. Increased use of fossil fuels not only depletes them but also contributes to global warming. By 2050, the usage of fossil fuels will be approximately lower than 80% than it is today. There is no yearly variation in the amount of CO2 in the atmosphere due to soil and land plants. Therefore, an alternative source of energy is required to overcome these problems. Biohydrogen is considered to be a renewable source of energy, which is useful for electricity generation rather than relying on harmful fossil fuels. Hydrogen can be produced from a variety of sources and technologies and has numerous applications including electricity generation, being a clean energy carrier, and as an alternative fuel. In this review, a detailed elaboration about different kinds of sources involved in biohydrogen production, various biohydrogen production routes, and their applications in electricity generation is provided.

“…Only in the first two months of the year, carbon and NO 2 emissions have been reduced by 25% and 30%, respectively, by social isolation and reduction in car traffic (Tahir & Masood, 2020). Biohydrogen is standing out among the other biofuels because it has zero contaminants because its only waste during oxidation is water (Oceguera-Contreras et al, 2019). Besides, it is the one with the highest energy content (120 kJ/g), approximately three times more than the energy content from fossil fuels such as gasoline with 41.2 kJ/g or diesel with 42.9 kJ/g for instance (Sekoai et al, 2019).…”

“…The yield of hydrogen production will depend on the type of microorganisms used and the final products of fermentation. Only one-third of the substrate can be used for hydrogen production; this is because two thirds of the substrate will form small acids, e.g., acetic and isobutyric acid (Zhao et al, 2013), when this process is carried out in a bioreactor, the yield of hydrogen production will now also depend on specific operating conditions such as the concentration of the substrate, pH, temperature and hydraulic retention, in order to obtain the highest possible yield (Oceguera-Contreras et al, 2019;W. Zhao et al, 2013).…”

La biología sintética tiene como objetivo desarrollar células con funciones totalmente nuevas y que no se encuentran en su naturaleza. Estas funciones se manifiestan a través de rutas creadas a partir de genes provenientes de otros microorganismos vinculados por técnicas moleculares como el ensamblaje de Bio-Brick. Algunos de estos enlaces pueden adoptar un comportamiento booleano y generar lo que se conoce como un circuito genético, compuesto principalmente por las partes funcionales de un gen (Promotor, RBS, ORF, Terminador). Estas piezas intercambiables forman lo que se conoce como Bio-Brick, que actúa como una puerta lógica al mostrar una estabilidad excelente y una memoria genética que perdura después de varias generaciones. Por los distintos tipos de comportamiento que presentan los Bio-Bricks, son muy atractivos para la industria, ya que con solo elegir un tipo de circuito sus aplicaciones son diversas, por ejemplo en la industria biomédica para (medicamentos contra el cáncer, la malaria, anticuerpos específicos e ingeniería del microbioma), o en la industria energética para (generar biocombustibles de segunda generación que compitan eficazmente con los combustibles fósiles; también se ha descubierto que por su utilidad en diferentes ámbitos, representa una solución a problemas como las altas emisiones de gases de efecto invernadero o la actual pandemia provocada por la aparición del SARS-CoV-2.

Marine biomass (such as wild seaweed Gracilaria verrucosa) is highly abundant in Indonesia and has been highlighted as a potential biomass resource for bioenergy production. Furthermore, agro-industrial waste (such as tofu dregs/TD which arises from large scale production in the country) is rich in carbohydrates and proteins, and is therefore considered a viable feedstock for production of high-value added products. This study aimed to investigate the co-digestion of wild seaweed G. verrucosa (WGv) with TD and its impacts on biogas and methane production. The biochemical methane potential (BMP) test was operated for 28 days at temperature of 37 o C. The co-digestion of WGv with TD at 90:10 and 80:20 ratios significantly increased the specific methane potential (SMP), giving an average of 98 LCH4/kgVS and 120 L CH4/kgVS, respectively. Addition of co-digestion substrates promoted co-metabolism in the digesters, increasing the ability of the microorganism to effectively digest the organic matter present in the feedstock's mixture. The washing pre-treatment reduced the concentration of inorganic compounds and salts within the wild seaweed G. verucosa, leading to an improvement in biogas and methane yield. The mass balance illustrated that this process configuration led to a reduction in the quantity of digestate to be managed (i.e. dewatering, transport, and land/soil application). This will subsequently reduce the cost and energy requirements for sludge management, estimated at 37%. Therefore, the co-digestion of WGv with TD and the application of a washing pre-treatment stage prior to AD can positively enhance biogas and methane production. Indepth investigation for optimal valorisation using AD technology is highly essential.
