Determination of the Thrombolytic Activity of Natto Extract
INTRODUCTION Bacillus subtilis, the species to which natto bacillus belongs, has been reported to secrete several proteases extracellularly during growth (1-4). Among these proteases, the physiological activity or clinical applications of antithrombotic substances contained in natto, such as the peptidase subtilisin, have been reported (5-8). Based on the results of this research, functional fo...
متن کاملCetyltrimethylammonium bromide-enhanced chemiluminescence determination of uric acid using a luminol-hexacyanoferrate(III)-hexacyanoferrate(II) system.
A chemiluminescence (CL) method using flow injection (FI) was developed for the determination of uric acid based on the enhancement chemiluminescence intensity of luminol-hexacyanoferrate(III)-hexacyanoferrate(II) in the presence of cetyltrimethylammonium bromide and the uric acid species. The linear range was 7.0 x 10(-10) - 9.0 x 10(-7) M with a detection limit (3sigma) of 2.58 x 10(-10) M, w...
متن کاملBacteriophages of Bacillus subtilis (natto) and Their Contamination in Natto Factories
Natto is a fermented soybean food, which is produced and consumed mainly in Japan (Nagai & Tamang, 2010). The Japanese usually eat natto with cooked rice, after mixing it with seasonings attached in a package or with soy sauce (Fig. 1). Natto has a characteristic odour of short-chain fatty acids and ammonia (Ikeda et al., 1984; Kanno & Takamatsu, 1987), and a highly viscous polymer, poly-γ-glut...
متن کاملSpectrofluorometric determination of trace amounts of terbium with 4-chlorosalicylic acid, EDTA, and cetyltrimethylammonium bromide.
The quadruple complex formed by terbium with 4-chlorosalicylic acid (CSA), EDTA and cetyltrimethylammonium bromide (CTMAB) has been used for the sensitive spectrofluorometric determination of terbium in mixed rare earths. The effect of the experimental conditions on the fluorescence intensity was defined. Under the optimum conditions selected, the fluorescence intensity was linear with the terb...
متن کاملIn silico analysis of Nattokinase from Bacillus subtilis sp natto
Nattokinase or subtilisin NAT (EC 3.4.21.62) is one of the most remarkable enzymes produced by Bacillus subtilis sp. Natto, which posses direct fibrinolytic activity. The aim of this study is in silico analysis of Nattokinase structure and function. The three-dimensional structure of serine protease Nattokinase from Bacillus subtilis sp. natto was determined using homology modeling performed by...
