| Response of kluyveromyces marxianus against osmotic stress kinetics, mechanism, and characterization during very high gravity bioethanol fermentation_Dr. Khairiah Abd Karim Stress induced by ethanol accumulation is a fe ctor that inhibits cellular growth during fermentation and reduced ethanol yields. To determine the effect of ethanol during growth of K/uyveromyces marxianus, fermentation wus performed at 40°C, 150 rpm for 72 h, in the presence of various ethanol concontrntions (5 - 25 % (v/v)). Under the condi... | 6/13/2019 | 3/4/2019 | Dr. Khairiah Abd Karim - Author | |
| Rock overstressing in deep tunnel excavation of pahang-selangor/Romziah Azit, Mohd Ashraf Mohamad lsmail, Sharifah Farah Fariza Syed Zainal Tunneling under high overburden and in-situ stress may cause tunnel instability because of rock overstressing. Evaluating overstressing in deep hard rocks is crucial to minimize excavation risks. The excavation of the Pahang-Selangor Raw Water Transfer Tunnel is evaluated in this study. A potential overstressing problem is expected at a tunnel dept... | 3/9/2020 | 6/9/2009 | Romziah Azit - Author Mohd Ashraf Mohamad lsmail - Author Sharifah Farah Fariza Syed Zainal - Author |
