| clostridium botulinum growth and toxin production in tomato juice containing aspergillus gracilis. | the ability of spores of one type a and one type b strain of clostridium botulinum to grow and produce toxin in tomato juice was investigated. the type a strain grew at ph 4.9, but not at ph 4.8; the type b strain grew at ph 5.1, but not at ph 5.0. aspergillus gracilis was inoculated along with c. botulinum spores into ph 4.2 tomato juice; in a nonhermetic unit, a ph gradient developed under the mycelial mat, resulting in c. botulinum growth and toxin production. in a hermetic unit, mold growth ... | 1979 | 36843 |

| purification, characterization, and potential of saline waste water remediation of a polyextremophilic α-amylase from an obligate halophilic aspergillus gracilis. | an obligate halophilic aspergillus gracilis which was isolated from a hypersaline man-made saltern from thailand was screened for its potential of producing extracellular α -amylase in the previous studies. in this study the α -amylase was extracted and purified by the help of column chromatography using sephadex g-100 column. presence of amylase was verified by sds-page analysis, showing a single band of approximately 35 kda. the specific activity of the enzyme was found to be 131.02 u/mg. the ... | 2014 | 24949415 |
