In this paper, capillary zone electrophoresis method was used for the determination of vitamin C and nicotinic acid content in black bean. 20 mmol/L borax solution and 20% acetonitrile concentration, 20kV voltage, 254 nm UV detection wavelength was chosen for electrophoretic analysis. Measured vitamin C and nicotinic acid content in black bean were 0.333 mg/g (RSD = 3.9%) (n = 5), 0.482 mg/g (R...

In this study, marine tunicate Styela clava hydrolysate was produced by an environment friendly and green technology, pressurized hot water hydrolysis (PHWH) at different temperatures (125–275 °C) and pressure 50 bar. A wide range of physico-chemical and bio-functional properties such as color, pH, protein content, total carbohydrate content, reducing sugar content, and radical scavenging activ...

By an improved method of hydroxylapatite chromatography, the reassociated sequences of chick nuclear DNA were isolated, and their base composition analysed. By increasing the amount of reassociation, the G + C content of the renatured sequences decreased progressively to reach a mean value corresponding to that of the total DNA. In order to study the distribution of the families, or group of fa...

Forsdyke (1999) has recently argued that differences in (G+C)%, or G+C content, may trigger new species formation. He further argues that the genic model has shortcomings that can be overcome by his "chromosomal" (hereafter, "G+C") model. We disagree on several counts. First, we do not accept that the genic model has the shortcomings suggested by Forsdyke. There is an abundance of empirical sup...

The objective of the present investigation was to determine the level of WSSV transmission from the infected tiger prawn Penaeus monodon to SPF Litopenaeus vannamei in laboratory captivity condition, in connection with to PCR detection and viral genome sequence. The nested PCR product band was ranged between 296 to 910 bp and was found during entire period from the experimental studies of SPF L...

The production of activated carbon from areca nut waste as a biosorbent for Ca and Mg in groundwater has been done. This research aimed to determine the ash content, water iodine number carbons optimum contact time adsorption capacity groundwater. Activated making is done by carbonation activation. activator used was H2SO4 1,5 M with soaking 24 hours. process carried out batches variations time...

The first world-known and largest outbreak of 36 cases of Guillain-Barré syndrome caused by a preceding Campylobacter jejuni infection was reported previously in China. During the outbreak, Campylobacter jejuni strain ICDCCJ07002 was isolated from a patient with persistent diarrhea for 21 days, and C. jejuni strain ICDCCJ07004 was from a healthy carrier without any clinical symptoms at the same...
