Salah satu energi alternatif terbarukan saat ini yang sedang dikembangkan untuk mengganti bahan bakar fosil adalah biohidrogen. Biohidrogen dapat diperoleh dari hasil fermentasi limbah biomassa berupa jeruk. Jeruk mengandung senyawa diolah menghasilkan hidrogen melalui anearob. Penelitian bertujuan mengetahui pengaruh variasi Organic Loading Rate buah jeruk diumpankan setiap harinya ke dalam bi...

This work describes a methodology for the valorization of non-food biomass production biosourced molecules via biohydrogen and metabolites fermentations such as volatile fatty acids. The commercial anion exchange resin Amberlite IRA-400(Cl) was chosen extraction carboxylic Different operating conditions were set up namely amount to be used, activation methods, pH their effects on capacity solve...

The maximum molar yield of hydrogen that can be obtained from a renewable sugar such as glucose is 12 mol H per mole glucose. In this work it has been shown that the enzymes of the oxidative 2 cyclic pentose phosphate pathway coupled to hydrogenase, using NADP as the electron carrier, is + capable of generating 11.6 mol H per mole of glucose-6-phosphate (G6P). These results provide the 2 first ...

Energy plays a crucial role in the sustainable development of modern nations. Today, hydrogen is considered most promising alternative fuel as it can be generated from clean and green sources. Moreover, an efficient energy carrier because burning only generates water byproduct. Currently, natural gas. However, produced using other methods, i.e., physicochemical, thermal, biological. The biologi...

Saccharina japonica (known as Laminaria or Phaeophyta japonica), one of the largest macroalgae, has been recognized food and medicine for a long time in some Asian countries, such China, South Korea, Japan, etc. In recent years, S. also considered most promising third-generation biofuel feedstock to replace fossil fuels, contributing solving challenges people face regarding energy environment. ...

BACKGROUND Molecular hydrogen, given its pollution-free combustion, has great potential to replace fossil fuels in future transportation and energy production. However, current industrial hydrogen production processes, such as steam reforming of methane, contribute significantly to the greenhouse effect. Therefore alternative methods, in particular the use of fermentative microorganisms, have a...

BACKGROUND Biological hydrogen production from lignocellulosic biomass shows great potential as a promising alternative to conventional hydrogen production methods, such as electrolysis of water and coal gasification. Currently, most researches on biohydrogen production from lignocellulose concentrate on consolidated bioprocessing, which has the advantages of simpler operation and lower cost ov...
