Ophiostomatoid and basidiomycetous fungi associated with green, red, and grey lodgepole pines after mountain pine beetle (Dendroctonus ponderosae) infestation
The mountain pine beetle (MPB) is a major concern for lodgepole pine (Pinus contorta var. latifolia Engelm.) forests in British Columbia, Canada. MPB and the ophiostomatoid staining fungi for which...

Enumeration of petroleum-degrading marine and estuarine microorganisms by the most probable number method.
Several media designed for use in a most probable number (MPN) determination of petroleum-degrading microorganisms were compared. The best results, i.e., largest numbers, were obtained using aExpand

Endophytic colonization of spruce by plant growth-promoting rhizobacteria
We evaluated internal tissue colonization of hybrid spruce (Picea glauca×P. engelmannii) seedlings by two plant growth-promoting rhizobacteria (PGPR) strains, Bacillus polymyxa strain Pw-2R andExpand

Comparison of the 3,5-dinitrosalicylic acid and Nelson―Somogyi methods of assaying for reducing sugars and determining cellulase activity
Abstract A comparison has been made between the 3,5-dinitrosalicylic acid (DNS) and alkaline copper methods of assaying for reducing sugars released during the enzymatic hydrolysis of cellulose byExpand

The use of enzyme recycling and the influence of sugar accumulation on cellulose hydrolysis by Trichoderma cellulases
The enzymatic hydrolysis of cellulose was initially investigated using the alkaline peroxide-treated fraction derived from steam-exploded Eucalyptus viminalis chips and a cellulase mixture of theExpand

Evaluation of Bacillus subtilis C186 as a potential biological control of sapstain and mould on unseasoned lumber
Bacillus subtilis C186 was evaluated as a potential biological control agent for sapstain and mould growth on unseasoned lumber. The strain produces antibiotics that are fungistatic to manyExpand

Partial purification and characterization of the lipase of a facultatively psychrophilic bacterium (Acinetobacter O16).
The extracellular lipase(s) of the psychrophile Acinetobacter O16 was studied. When the enzyme was precipitated by (NH4)2SO4 and passed through a Sephadex G200 column, two peaks of lipase activityExpand
