Optimisation of biodegradation conditions for cyanide removal by Serratia marcescens strain AQ07 using one-factor-at-a-time technique and response surface methodology
(Accademia Nazionale dei Lincei, 2016-03-12)Gold mining companies are known to use cyanide to extract gold from minerals. The indiscriminate use of cyanide presents a major environmental issue. Serratia marcescens strain AQ07 was found to have cyanide-degrading ... -
Optimization of Aloe vera and alginate as encapsulating matrices for Lactobacillus acidophilus using FCCD-RSM approach
(Institute of Electrical and Electronics Engineers (IEEE), 2013)In order to maintain the viability of probiotic, the used of prebiotic is important. Aloe vera has been hypothesized to be a prebiotic potential for probiotic. Due to low viability of encapsulated cells, Aloe vera gel was ... -
Optimization of milk-based medium for efficient cultivation of bifidobacterium pseudocatenulatum g4 using face-centered central composite-response surface methodology
(Hindawi Publishing Corporation, 2014)This study was undertaken to optimize skim milk and yeast extract concentration as a cultivation medium for optimal Bifidobacteria pseudocatenulatum G4 (G4) biomass and β-galactosidase production as well as lactose and ... -
A proposed aerobic granules size development scheme for aerobic granulation process
(Elsevier, 2015-04-01)Aerobic granulation is increasingly used in wastewater treatment due to its unique physical properties and microbial functionalities. Granule size defines the physical properties of granules based on biomass accumulation. ... -
Removal of Ni(II), Zn(II) and Pb(II) from aqueous solutions using cation-exchange resin in fixed-bed column
(Taylor and Francis Ltd., 2015-10-13)Breakthrough curves for the removal of Ni(II), Zn(II), and Pb(II) from aqueous solutions using cation exchange resin (Dowex 50W) were determined at dynamic conditions in a fixed-bed column under ambient temperature. The ... -
Screening of Aloe vera medium with different carbon and nitrogen sources for lactobacillus acidophilus cultivation using fractional factorial design (FFD)
(Institute of Electrical and Electronics Engineers (IEEE), 2013)The aim of this research was to optimize the cultivation medium for economic production of a probiotic bacterium, Lactobacillus acidophilus using Aloe vera medium with different carbon (glucose, fructose and sucrose) and ... -
Synergistic effect of up-flow constructed wetland and microbial fuel cell for simultaneous wastewater treatment and energy recovery
(Elsevier, 2016-03-01)This study demonstrated a successful operation of up-flow constructed wetland-microbial fuel cell (UFCW-MFC) in wastewater treatment and energy recovery. The goals of this study were to investigate the effect of circuit ... -
The use of lates calcarifer as a biomarker for heavy metals detection
(Springer Milan, 2016-01-21)Fish are ubiquitous organisms that have many features that designate their potential as a biomarker of heavy metals pollution. Thus, an investigation was done to detect the effect of heavy metals on cholinesterase (ChE) ...
