摘要
液体发酵野油菜黄单胞菌,生产大量菌液,通过离心、浓缩获得野油菜黄单胞菌色素干品,进行热、光照、酸碱度对色素稳定性的影响试验。结果表明,野油菜黄单胞菌黄色素在高温、长时间光照、强酸碱度条件下,性状稳定,吸收波长稳定在330 nm。
A heat, light and pH test on the influence on the stability of the pigment of xanthomonas eampestris is carried out with the dry pigment of xanthomonas campestris produced in a large number of bacilli obtained from liquid fermentation of xanthomonas campestris through centrifuging and concentrating. The result indicates that the characters and state of pigment of xanthomonas eampestris are stable when exposed to high temperature, a long-time light and strong pH with a stable absorbing of wavelength at 330 nm.
