“…The source of biogenic hydrogen bacteria varies widely, such as heat treatment of shrimp ponds to produce hydrogen‐producing bacteria, abundant light, and the high organic matter content of pig farms in the sludge discharge enrichment of photosynthetic bacteria. Isolated from water production wells, hydrogen strains ( thermoanaerobacter mathranii A3N ) obtain the community of hydrogen‐producing bacteria and prepare the cyanobacterium anabaena algae from the soil, commercial fertilizers, and sewage plant sludge …”

Summary The progress of bio‐hydrogen technology has led to the development of new energy technologies and is significant for the sustainable use of energy. After summarizing current research results, this study discusses that the key to increasing the hydrogen production rate is to improve the activity of hydrogen producing bacteria under the conditions of anaerobic fermentation. Using waste to prepare hydrogen producing bacteria is the developmental trend. The primary factors influencing bio‐hydrogen production from plant straw fermentation are also pointed out, indicating the method to improve the hydrogen production rate from plant straw. In addition, application of artificial intelligence technology to a bio‐hydrogen production reactor is helpful to achieve automatic control of continuous bio‐hydrogen production and improve the rate of hydrogen production.

“…After this pre-treatment, it is ready to pour into the reactor tank. The performance of this bacterial biomass from the water treatment plant of a ship has been compared to other sources in previous work [12], showing outstanding hydrogen production. Genetic analysis of 16S rRNA on the untreated sludge has shown that it is composed of over 25 different bacterial families, but this is notoriously reduced by the temperature pretreatment.…”

“…Hydrogen-producing bacteria can be collected from several natural sources. In a previous contribution, the authors reported evidence on the feasibility of using bacterial communities from different sources [12,13]. The one extracted directly from a wastewater treatment plant on board a navy ship was selected, considering the convenience of in situ production for ship maintenance.…”

Dark fermentation is a hydrogen generating process carried out by anaerobic spore-forming bacteria that metabolize carbon sources producing gas and short-chain acids. The process can be controlled, and the hydrogen harvested if bacteria are grown in a reactor with favorable conditions. In this work, bacteria selected from natural sources were grown with a defined culture media, while pH was monitored, with the aim of relating the amount of generated hydrogen to the increase in hydron ion concentration. Therefore, a model based on the acid-base species mass balance is proposed and solved to estimate the lag phase time and measure the hydrogen production efficiency and kinetics. Hydrogen production in a stirred batch reactor was performed for 150–200 h, at given operating conditions using a previously defined growth media, to validate the model. Using the proposed model, the cumulated moles of produced hydrogen correlate well with those predicted from the pH curve. Hence, the modified Gompertz model parameters, largely used for describing the hydrogen generation kinetics by dark fermentation, were estimated from the pH curve and from the experimentally measured generated hydrogen. Satisfactory agreement was found, thus, validating the method.
