Summary: The hydrogen-producing bacteria, Clostridium butyricum (SP4) and Clostridium beijerinckii (SP6), were isolated from compost. They showed different biohydrogen-producing activities when using different types of sugars as substrates. The efficiency of converting wastewater to hydrogen by C. butyricum SP4 was slightly lower than that of C. beijerinckii SP6. The metabolic capabilities and kinetic parameters of these bacteria provide valuable information for optimizing the technology of biohydrogen production.

Summary: The large quantities of palm oil mill effluent (POME) create a significant pollution problem. In this study, we demonstrate that the introduction of plasma and MHz-order sound waves can greatly reduce the treatment time and improve the removal of pollutants in POME. Plasma exposure enhances oxygen dissolution and organic compound dissolution, while sound waves promote convective mass transfer and bacterial decomposition. Combining plasma pretreatment and sound wave irradiation can lead to a fivefold reduction in the total treatment duration, making this hybrid technology promising for industrial-scale treatment systems.

Summary: The concept of biological hydrogen production was first proposed in the early 19th century, but it did not gain much attention until the 1930s when H-2 production was reported through anaerobic digestion of cellulose using microbes present in ruminant tract. Subsequent developments in fermentative H-2 production were achieved by researchers utilizing advanced technologies in fermentative systems. This review highlights major technological aspects such as genetic engineering, nanomaterial implementations, immobilization techniques, and reactor configuration developments associated with H-2 production through the fermentative process.
