• Active-site- and substrate-specificity of Thermoanaerobium Tok6-B1 pullulanase. 

  Plant, Adrian R.; Clemens, Robyn M.; Morgan, Hugh W.; Daniel, Roy M. (1987)

  Thermoanaerobium Tok6-B1 pullulanase (EC 3.2.1.41) was active on alpha 1-6-glucosidic linkages of pullulan, amylopectin and glycogen and the alpha 1-4 linkages of amylose, amylopectin and glycogen but not of pullulan. ...

• Aspects of protease production by Thermus strain Ok6 and other New Zealand isolates 

  Jones, Colin W.; Morgan, Hugh W.; Daniel, Roy M. (1988)

  Thirteen strains of Thermus isolated from New Zealand hot pools were screened for their ability to grow on minimal or near-minimal media and to exhibit extracellular protease activity. Environmental regulation of protease ...

• Biochemical characterization of an active pyrophosphate-dependent phosphofructokinase from Treponema pallidum 

  Roberson, Russell S.; Ronimus, Ron S.; Gephard, Susanne; Morgan, Hugh W. (2001)

  An active pyrophosphate-dependent phosphofructokinase containing a six residue polyhistidine tag has been cloned from Treponema pallidum, and characterized biochemically. The phosphofructokinase has pH optima for activity ...

• Caldolase, a chelator-insensitive extracellular serine proteinase from a Thermus spp. 

  Saravani, G.A.; Cowan, Don A.; Daniel, Roy M.; Morgan, Hugh W. (1989)

  An extracellular alkaline serine proteinase from Thermus strain ToK3 was isolated and purified to homogeneity by (NH4)2SO4 precipitation followed by ion-exchange chromatography on DEAE-cellulose and QAE-Sephadex, affinity ...

• Caldolysin, a highly active protease from an extremely Thermophilic Bacterium 

  Cowan, Don A.; Daniel, Roy M.; Morgan, Hugh W. (New Zealand Institute of Chemistry, 1982)

  Proteases comprise a significant proportion of those proteins which have been subject to detailed characterisation (amino acid sequence and high resolution crystallographic analysis). The extent of research interest in ...

  

• Effects of environmental factors on wood decay micromorphology of Pinus radiata and Fagus sylvatica, and its significance for in-ground wood preservative performance 

  Wakeling , Robin Nicholas (The University of Waikato, 2003)

  Wood preservatives are essential to the continued use of wood in situations where fungal decay and damage from wood boring insects such as termites, would otherwise occur. Significant risks to health and the environment ...

  

• The microbial ecology and colonisation of surfaces in selected hot springs - a molecular-and culture-based approach 

  Niederberger, Thomas D. (The University of Waikato, 2005)

  Traditionally, culture-based approaches have been used to investigate the microbial ecology of thermal habitats. The emergence of alternate molecular approaches based on DNA sequences has shown that terrestrial thermal ...

  

• Enumeration and discrimination of thermophilic bacilli in milk powder 

  Rückert, Andreas (The University of Waikato, 2005)

  A survey of milk powders from eighteen different countries has established that the same cohorts of strains of thermophilic bacilli are the major contaminants regardless of source. In particular, Anoxybacillus flavithermus ...

  

• Nitrogen fixation and bulk organic removal in a bleached krall pulp and paper mill treatment system 

  Frost, Nicola M. (The University of Waikato, 1998)

  A study was undertaken to assess some effects of nitrogen fixation and bulk organic substrate removal in a New Zealand bleached kraft pulp and paper mill wastewater treatment system. A novel wastewater biological treatment ...

  

• Survival and recovery of Escherichia coli O157:H7 during starvation at sub-optimal temperatures 

  Xavier, Ron Neo (University of Waikato, 2014)

  Escherichia coli O157:H7 is an important foodborne pathogen with a dual lifestyle of growth within a host and persistence in non-host environments. Environmental survival of E. coli O157:H7 is particularly important in New ...
