Enzymatic hydrolysis of market vegetable waste and subsequent ethanol fermentation-Kinetic evaluation
Written by   Published On Issue 4 Vol 5, 2014
In this work, kinetic properties evaluation was made for bioethanol production from sugar hydrolysate of vegetable waste. The saccharified sugars were fermented by using Saccharomyces cerevisiae. The effect of various saccharification factors on sugars release were studied and observed that the optimized conditions contributed to 14.4 gL-1of fermentable sugars production. The produced sugars were subjected to batch fermentation by Saccharomyces cerevisiae at pH 4.5 and the kinetic parameters of

Enhanced safety and protection of glutamate induced hippocampal neuronal cells damage by Neurotol
Written by   Published On Issue 4 Vol 5, 2014
p { margin-bottom: 0.21cm; }We investigated the neuroprotective effect of Neurotol (Mannitol 10% + Glycerin 10% + RD011 1.5 %) against neuronal damage induced by glutamate compared to Neurotol M (Mannitol 20%), Kratol and Zemisol. Exposure of neuronal cells to glutamate caused concentration dependent neuronal damage as evident by significant increase in LDH activities (P<0.05 to P<0.001). The neuronal cell toxicity by exposure to glutamate involves an apoptotic process. However, among the

Carotenoid Production by Bacillus clausii Using Rice Powder as the Sole Substrate: Pigment Analyses and Optimization of Key Production Parameters
Written by   Published On Issue 4 Vol 5, 2014
Natural β-carotene, an orange–red pigment of carotenoid family is widely used as food colorant. In this study microbial method of pigment production is adopted to encompass the other expensive technologies. Influence of substrate (rice powder) on β-carotenoid production has been extensively studied at optimum process conditions such as pH, temperature etc. A novel β-carotenoid producing pigment Bacillus clausii was isolated and identified by physiological tests as well as 16s rDNA sequence

Phenol removal by soluble and alginate entrapped turnip peroxidase
Written by   Published On Issue 4 Vol 5, 2014
This paper is a comparative study of phenol biodegradation by soluble and alginate entrapped turnip (Brassica rapa) peroxidase. The effects of relevant factors on the process such as pH, temperature, concentration of H2O2, phenol concentration, enzyme activity and contact time were evaluated in order to optimize the conditions for maximum phenol removal.  Results showed that the obtained average removal yield under optimal conditions was 93%.  The process duration was 3 hours. The reac

Shemamruthaa, herbal formulation modulates xenobiotic metabolizing enzymes and energy metabolism in 7,12-Dimethylbenz[a]anthracene-induced breast cancer in rats
Written by   Published On Issue 4 Vol 5, 2014
There is an increasing interest in identifying naturally occurring potent preventive and therapeutic agents for cancer. Shemamruthaa, a phytochemical formulation was evaluated for the first time with a view to potentiate more intense anticancer property. Adult female Sprague-Dawley rats (8-week-old) were used for the study and were divided into 4 Groups. Group I control animals received standard pellet diet and water ad libitum. Group II animals were induced for mammary carcinoma with a single o

Effect of PGR producing bacterial strains isolated from vermisources on germination and growth of Vigna unguiculata (L.) Walp.
Written by   Published On Issue 4 Vol 5, 2014
Nineteen bacterial strains were isolated from vermisources andscreened for Indole-3-acetic acid (IAA) production among themonly nine strains produce IAA and they were identified asStreptococcus spp., Micrococcus spp., Klebsiella spp., Bacillus spp., Enterobacter spp., Escherichia spp., Alcaligenes spp., Erwinia spp., and Pseudomonas spp. Among all other strains Bacillus sp. showed the higher IAA production hence selected for further molecular analysis and confirmed as Bacillus cereus. The B. cer

Preparation of guava wine using immobilized yeast
Written by   Published On Issue 4 Vol 5, 2014
Saccharomyces cerevisiae (NCIM 3287) was immobilized in sodium alginate beads to produce a biocatalyst for use in guava wine making. The immobilized biocatalyst was found to be suitable for guava juice fermentation at ambient temperatures. The study included effects of alginate concentrations, initial bead loadings and bead diameters on fermentation. The optimized parameters were  2% (w/v) alginate concentration, 60g/l initial bead loading and        &nbsp

Magnetite nanoparticle aided immobilization of Pseudomonas sp. GBS.5 for carbazole degradation
Written by   Published On Issue 4 Vol 5, 2014
Pseudomonas sp. GBS.5 is a newly isolated biosurfactant producing and carbazole degrading bacterium. In the present study, this bacterium was coated with magnetite nanoparticles, synthesized using co-precipitation method. Scanning electron microscopy (SEM) studies confirmed the coating of the bacterial surface with these nanoparticles. Degradation activity of the coated cells obtained was 1.4 ppm/min as compared to 0.32 ppm/min for free cells and could be reused for five different cycles. These

Real-Time kinetic studies of Bacillus subtilis oxalate decarboxylase and Ceriporiopsis subvermispora oxalate oxidase using a luminescent oxygen sensor
Written by   Published On Issue 4 Vol 5, 2014
Oxalate decarboxylase (OxDC), an enzyme of the bicupinsuperfamily, catalyzes the decomposition of oxalate into carbondioxide and formate at an optimal pH of 4.3 in the presence ofoxygen. However, about 0.2% of all reactions occur through anoxidase mechanism that consumes oxygen while producing twoequivalents of carbon dioxide and one equivalent of hydrogenperoxide. The kinetics of oxidase activity were studied bymeasuring the consumption of dissolved oxygen over time using a luminescent oxygen s
