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 ... -
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 ... -
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 ... -
Isolation and characterization of a molybdenum-reducing and amide-degrading burkholderia SP. Strain neni-11 in soils from west sumatera, Indonesia
(Institute of Integrative Omics and Applied Biotechnology (IIOAB), 2016-01-01)A molybdenum-reducing bacterium isolated from contaminated soil was able to utilize acrylamide as the electron donor source, and was able utilize acrylamide, acetamide and propionamide for growth. Reduction was optimal at ... -
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 ... -
Characterization of a diesel-degrading strain isolated from a hydrocarbon-contaminated site
(Triveni Enterprises, 2009-01)A diesel-degrading bacterium has been isolated from a diesel-polluted site. The isolate was tentatively identified as Staphylococcus aureus strain DRY11 based on partial 16S rDNA molecular phylogeny and Biolog® GP microplate ... -
Growth kinetics of a diesel-degrading bacterial strain from petroleum-contaminated soil
(Triveni Enterprises, 2014-03)A diesel-degrading bacterium was isolated from a diesel-contaminated site in Selangor, Malaysia. The isolate was tentatively identified as Acinetobacter sp. strain DRY12 based on partial 16S rDNA molecular phylogeny and ... -
Acetylcholinesterase from Puntius javanicus for the detection of carbamates and organophosphates
(SPB Pharma Society, 2015-04-01)A new alternative local source of acetylcholinesterase (AChE) has been found to be sensitive towards several insecticides. AChE was purified from the brain tissue of Puntius javanicususing affinity chromatography (procainamide ... -
Cholinesterase-based biosensor using Lates calcarifer (Asian Seabass) brain for detection of heavy metals
(SPB Pharma Society, 2015-04-01)Heavy metals are sometimes needed for nutrient uptake but only in low concentrations and the nervous system is the most susceptible to be affected. Cholinesterase (ChE) inhibition has been used extensively as a biomarker ... -
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 ... -
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 ... -
Characteristics of developed granules containing phototrophic aerobic bacteria for minimizing carbon dioxide emission
(Elsevier Limited, 2015-08-01)Photosynthetic process compromises the most effective and natural way for carbon recycling, in which photosynthetic bacteria utilized carbon dioxide (CO2) during the wastewater treatment processes. The aim of this study ... -
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) ... -
Decanter cake as a feedstock for biodiesel production: A first report
(Elsevier Ltd., 2013)Decanter cake (DC), with an oil content of 11.5 ± 0.18 wt.%, was subjected to ultrasound-aided transesterification using boiler ash as a base catalyst, petroleum ether and hexane as co-solvents. Optimization work revealed ...
