Comparison of Joint Effect of Acute and Chronic Toxicity for Combined Assessment of Heavy Metals on Photobacterium sp.NAA-MIE
Nur Adila Adnan,Mohd Izuan Effendi Halmi,Siti Salwa Abd Gani,Uswatun Hasanah Zaidan,Mohd. Yunus Abd. Shukor +4 more
TL;DR: In this paper, the authors used newly isolated Photobacterium sp.NAA-MIE as the indicator to predict acute and chronic toxicity based on luminescence inhibition assay.
Journal ArticleDOI
Lipase-catalyzed synthesis of red pitaya (Hylocereus polyrhizus) seed oil esters for cosmeceutical applications: process optimization using response surface methodology

TL;DR: In this article, a central composite response surface design was used to evaluate the effect of synthesis parameters, including temperature, time, substrate molar ratio and enzyme loading, on the yield and productivity of esters.
Journal ArticleDOI
Improvement of Ficin-Based Inhibitive Enzyme Assay for Toxic Metals Using Response Surface Methodology and Its Application for Near Real-Time Monitoring of Mercury in Marine Waters
Garba Uba,Motharasan Manogaran,Baskaran Gunasekaran,Mohd Izuan Effendi Halmi,Mohd. Yunus Abd. Shukor +4 more
TL;DR: The heavy-metal assay based on the protease ficin was optimized for mercury detection using response surface methodology and the results show a marked improvement for the concentration causing 50% inhibition (IC50) for mercury, silver and copper.
A rapid inhibitive assay for the determination of heavy metals using α-chymotrypsin; a serine protease
M. Z. Sahlani,Mohd Izuan Effendi Halmi,Noor Azlina Masdor,Helmi Wasoh,Mohd Arif Syed,Mohd. Yunus Abd. Shukor +5 more
TL;DR: In this article, an enzymatic-heavy metal assay has been developed using α-chymotrypsin; a serine protease for the detection of xenobiotics is a promising low cost and rapid method for monitoring.
Journal ArticleDOI
