Characteristics of proteinases and lipases produced by seven Bacillus sp. isolated from milk powder production lines

Chen, L.; Coolbear, Tim; Daniel, Roy M. (Elsevier, 2004)

Seven Bacillus strains isolated from milk powder production lines were grown in two selective media. All the strains produced extracellular and intracellular proteinase and lipase activity, but at different levels. Proteolytic ...
The effect of metal ions on the activity and thermostability of the extracellular proteinase from a thermophilic Bacillus, strain EA.1.

Coolbear, Tim; Whittaker, J.M.; Daniel, Roy M. (1992)

The proteinase from the extremely thermophilic Bacillus strain EA.1 exhibits maximum stability at a pH of approx. 6.5. In the presence of calcium ions the half-life at 95 degrees C of the enzyme at this pH was 17 min, and ...
Proteases from extreme thermophiles

Coolbear, Tim; Daniel, Roy M.; Cowan, Don A.; Morgan, Hugh W. (Wiley, 1988)

Extremely thermophilic bacteria are those that grow optimally at 65 ℃ or higher. Comparative data are presented on extracellular proteases from two extremely thermophilic eubacteria and one extremely thermophilic ...
Purification and characterization of a thermostable proteinase isolated from Thermus sp. strain Rt41A

Peek, Keith; Daniel, Roy M.; Monk, Colin R.; Parker, Lynne; Coolbear, Tim (Wiley, 1992)

Thermus sp. strain Rt41A produces an extracellular thermostable alkaline proteinase. The enzyme has a high isoelectric point (10.25–10.5) which can be exploited in purification by using cation-exchange chromatography. The ...
Purification and properties of an aryl beta-xylosidase from a cellulolytic extreme thermophile expressed in Escherichia coli.

Hudson, R.C.; Schofield, L.R.; Coolbear, Tim; Daniel, Roy M.; Morgan, Hugh W. (1991)

An aryl beta-xylosidase was purified to homogeneity from an Escherichia coli strain containing a recombinant plasmid carrying a beta-xylosidase (EC 3.2.1.37) gene from the extremely thermophilic anaerobic bacterium isolate ...

Thermophilic enzymes and their impact on milk powder during storage

Chen, Lin (The University of Waikato, 2000)

Milk powder quality and storage life can be compromised by functionality and flavour defects. These defects can be the result of chemical or biochemical reactions, such as the Maillard (browning) reaction, proteolysis and ...
