Due to rapid growth in population and societal development, the demand for energy is on increase. The production of palm oil as one major edible oils consumed world has increased tremendously. Palm mill effluent (POME), a wastewater from most significant agricultural industry produced tremendous amounts that requires proper management mitigate its negative environmental effects. Studies have sh...

High utilization of palm oil in Indonesia corresponds to mill effluent (POME). The POME has chemical oxygen demand (COD) up 100.000 mg/L, which can pollute the ecosystem if not adequately treated. One methods manage is anaerobic thermophilic digestion. advantage this method production methane gas a form alternative energy. Substrate concentration affects This preliminary experiment aims evaluat...

Coenzyme F(420)-dependent sulfite reductase (Fsr) of Methanocaldococcus jannaschii, a sulfite-tolerant methanogen, was expressed with activity in Methanococcus maripaludis, a sulfite-sensitive methanogen. The recombinant organism reduced sulfite to sulfide and grew with sulfite as the sole sulfur source, indicating that Fsr is a sulfite detoxification and assimilation enzyme for methanogens and...

Plant sulfite reductase (SiR; Enzyme Commission 1.8.7.1) catalyzes the reduction of sulfite to sulfide in the reductive sulfate assimilation pathway. Comparison of SiR expression in tomato (Solanum lycopersicum ‘Rheinlands Ruhm’) and Arabidopsis (Arabidopsis thaliana) plants revealed that SiR is expressed in a different tissue-dependent manner that likely reflects dissimilarity in sulfur metabo...
