Research ArticleOpen accessEvery word in the titleMedia Improvement for Hydrogen Production Using C. acetobutylicum NCIMB 13357Mohd Sahaid Kalil, Hisham Salem Saleh Alshiyab, Wan Mohtar Wan YusoffProblem statement: Some component of fermentation medium showed to reduce the bacterial production of hydrogen. Approach: Reinforced clostridium medium is a selected medium for Clostridium species. Reformulation this medium regarding hydrogen production may focus on such medium composition that enhance or reduce the bacterial productivity. The optimum pH and temperature for hydrogen production were at initial pH of 7.0 and … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,255 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleImprovement of Biohydrogen Production under Increased the Reactor Size by C. acetobutylicum NCIMB 13357Hisham Salem Alshiyab, Mohd Sahaid Kalil, Aidil Abdul Hamid, Wan Mohtar Wan YusoffProblem statement: One of the main factors influenced the bacterial productivity and total yield of hydrogen is the partial pressure of produced gas. A novel solution to enhance the bacterial productivity was through reduction of gas pressure. Approach: Increasing the reactor size showed to enhance the bacterial production of hydrogen. Results: The technique of increasing reactor size resulted to enhance … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,361 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleEffect of Nitrogen Source and Carbon to Nitrogen Ratio on Hydrogen Production using C. acetobutylicumMohd Sahaid Kalil, Hisham Salem Alshiyab, Wan Mohtar Wan YusoffProblem statement: One of the main factors influenced the bacterial productivity and total yield of hydrogen is the nitrogen source and its concentration. Approach: Using different nitrogen source with different concentration on bacterial productivity of hydrogen showed to affect on both bacterial productivity of hydrogen and biomass concentration. Results: Yeast extract as nitrogen source at concentration of 13 g L-1 … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2009 · 7,837 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleTrace Metal Effect on Hydrogen Production Using C.acetobutylicumHisham Alshiyab, Mohd Sahaid Kalil, Aidil Abdul Hamid, Wan Mohtar Wan YusoffThis study was carried out to study the effect of trace metal addition for hydrogen production The results show that this bacterial need a selected nutrient with selected concentration. The optimum parameters for cultivation were at initial pH of 7.0 and temperature of 30°C. Trace metal addition to the new medium showed that only iron enhanced the H2 yield. The … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 7,635 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUtilization of Rumen Content by Indigenous Microorganisms in a Modified Anaerobic DigesterAlhassan Salihu Adam, Sani Yahaya, Haruna Musa et al.The current work was designed to assess the effect of modification of model digester on the kinetics that affects efficiency in biogas generation using bovine rumen content as the feedstock. A biogas plant consisting of conventional and modified fixed-dome digesters (each with 2 m3 capacity) was established; and bovine rumen content was used as feedstock. Standard methods were used to … …Energy Research Journal, Vol. 11, Issue 1 · 26 Sep 2020 · 6,780 accessesView PDF Cite
