摘要
|
The purpose of this study was to reclaim squid pens for the production of
chitosanases and biosorbents of food colorants and industrial dyes via Bacillus
cereus fermentation. B. cereus TKU044 produced chitosanases at a high productivity
of 2.66 U/mL, when squid pens were used as the sole carbon and nitrogen
source. An extracellular chitosanase, with a molecular weight of 43 kDa, was
purified 286-fold with a 16% activity yield. TKU044 and five other chitosanaseproducing
strains of B. cereus have been used as biosorbents to investigate their
adsorption capacity on 0.025% (w/v) of colorants and dyes. For colorants, only Red
7 was adsorbed by the five B. cereus cells, whereas all tested B. cereus strains
showed adsorption effects with the dyes. The adsorption of Yellow 4 by squid pens
before and after 1 day of fermentation by B. cereus was also studied. |
