Development of a sequence characterized amplified region (SCAR) marker for identification of Thai jasmine rice (Oryza sativa L.) variety ‘KDML105’
The varieties of rice are difficult to be distinguished because of their similar morphological characters, therefore rice variety identification or differentiation is very important. The authentication by using molecular marker or DNA fingerprinting is the most accurate method. In this study, random amplified polymorphic DNA (RAPD) derived sequence characterized amplified region (SCAR) markers were applied to...

Mutational analysis of fructose-1,6-bisphosphate aldolase of Neisseria meningitidis serogroup B
Fructose-1,6-bisphosphate aldolase (FBA) is a classical cytoplasmic glycolytic enzyme which, despite lacking a predicted signal peptide, has been demonstrated to be expressed and transported to the surface of numerous Gram-positive bacteria and shown to interact with host molecules and perform non-glycolytic biological functions. Genome-based studies have also demonstrated that the glycolytic pathway appears to be...

In vitro propagation of Ceropegia thwaitesii Hook- an endemic species of Western Ghats of Tamil Nadu, India
In vitro propagation of Ceropegia thwaitesii Hook (Asclepiadaceae), an endemic plant species of Western Ghats, Tamil Nadu (India), was carried out. Auxiliary bud explants were cultured on Murashige and Skoog (MS) medium fortified with cytokinins (KIN), 6-benzyl adenine (BA), 2-isopentenyladenine (2-iP) and thidiazuron (TDZ) in various concentrations and in combination with auxins indole-3-butyric...

Characterization of water uptake and distribution in chickpea (Cicer arietinum L.) seeds during germination by NMR spectroscopy
Experiments were conducted to characterize the changes in water status during imbibition by nuclear magnetic resonance (NMR) spectroscopy in chickpea seeds exposed to static magnetic fields of 100 mT for 1 h. Water uptake during seed germination showed three phases with rapid initial hydration phase I, followed by lag phase II and steady hydration phase III. Comparative analysis of the hydration pattern showed that...

Genotype variation in grain yield response to basal N fertilizer supply among different rice cultivars
Considering the great amount of basal N fertilizer but lower uptake ability at rice seedling, it was essential to increase the N use efficiency of basal fertilizer and reduce N pollution. So, a field experiment was conducted at Wuxi, China, under non-basal N and basal N fertilizer conditions, to identify the variation of grain yield response to basal fertilizer among 199 rice varieties with different genetic background,...

Heavy metals burden of Keenjhar Lake, District Thatta, Sindh, Pakistan
Detection of heavy metals (HMs) content from Keenjhar Lake water was carried out monthly from January to December, 2003. Zinc, chromium, copper, iron, manganese, nickel and cadmium were analyzed by dual mode of analytical methods flame atomic absorption spectrometry and electrothermal atomic absorption spectrometry (FAAS and ETAAS) by multi element standard solution. The concentrations of zinc, chromium, copper, iron,...

Production of phytate-hydrolyzing enzymes by thermophilic moulds
138 isolates of thermophilic/thermotolerant moulds were isolated from soil, straw and compost samples, collected from various regions of India. Among the thermophilic fungal isolates screened for the secretion of phytase (phytate-hydrolyzing enzyme),Sporotrichum thermophile BJTLR50 produced a very high enzyme titre at pH 5.0, 45°C and 250 rpm in 5 days with an inoculum level of 1 × 107 spores per 50...

Effects of various additives on antioxidant and antimicrobial effectiveness in emulsion-type sausages
We investigated the effects of rosemary extract (RE), α-tocopherol (AT) and chitosan (CH) added individually or in combination as compared with butylated hydroxyanisole (BHA) on microbiological parameters [total viable count (TVC), lactic acid bacteria (LAB), enterobacteria (ENB), pseudomonas bacteria (PSY)], pH and lipid oxidation of emulsion-type sausages stored for 28 days at 4°C. TVC, LAB, ENB, and...

Survivability of probiotics in symbiotic low fat buffalo milk yogurt
In present study, symbiotic low fat buffalo milk yogurt prototypes (plain and blueberry) were developed using a commercial starter containing probiotics. Samples were analyzed for physicochemical and microbiological properties, and the survivability of probiotics during 10 weeks of storage. Gross composition results were: total solids 11.60 ± 0.58 and 17.12 ± 0.36%, ash 0.82 ± 0.06 and 0.78 ±...

Response surface methodology for optimization of the treatment of textile wastewater by a novel bacterial consortium: Enzymes and metabolites characterization
Textile wastewater (TWW) causes many environmental problems, and colored substances must be removed from it before their discharge into the environment. An optimization process was analyzed using custom response surface methodology (RSM). In the present study, the effect of different combinations of eight strains was studied using equilateral triangle diagram (Minitab 14.0) and mixture experimental design to assess...

Enzymatic epoxidation of biodiesel optimized by response surface methodology
During the enzymatic epoxidation of biodiesel, stearic acid was selected as oxygen carrier. Enzyme screening and the load of stearic acid were investigated. The effects of four main reaction conditions including reaction time, temperature, enzyme load, and mole ratio of H2O2/C=C-bonds on the epoxy oxygen group content (EOC) of epoxidized biodiesel were analyzed. Response surface methodology (RSM) was employed to study...

Pathological study of parasitism in racing pigeons: An indication of its effects on community health
Several non-official reports from different clinics, governmental veterinary head-quarters and bird keepers indicate that most of the young pigeons die with suspicious infection to parasites. In addition, the pigeon owners were complaining of skin itching on their head. Thus, this research was conducted to determine the pathological study of parasitism in racing pigeons with an indication of its effects on...

Comparison of broiler performance, carcass yields and intestinal microflora when fed diets containing transgenic (Mon-40-3-2) and conventional soybean meal
This study was conducted to analyze the effects of transgenic glyphosate-tolerant soybeans on the performance, carcass yields and intestinal microflora of broiler chickens. Three hundred and sixty one-day-old Abor Aerec broilers were randomly divided into two dietary treatments, adding genetically modified (GM) glyphosate-tolerant soybean meal or conventional soybean meal, respectively. Broiler...
