Bioprotection of unseasoned Ponderosa pine lumber from microbial discoloration

Creator:

Kreber, Bernhard

Abstract:

The potential of 9 bacterial and 6 fungal isolates to protect wood against wood staining microorganisms was studied using small sapwood samples of unseasoned Ponderosa pine [Pinus ponderosa Laws] sapwood. Bacillus subtilis Cohn, isolate 733 A , Gliocladium virens J.H. Miller, J.E. Giddens & A.A. Foster isolate H 3 and...

Fungitoxicities of NaMDC decomposition products to decay fungi colonizing Doulgas-fir and ponderosa pine wood

Creator:

Canessa, Edwin

Abstract:

Metham sodium or NaMDC is one of the four major soil fumigants that are currently registered for controlling internal decay of wood products in use. Fumigants are used primarily in utility poles but are also applied to piling, timbers and other large wood members. NaMDC must decompose to fungitoxic compounds...

The role of lytic enzymes in biocontrol of sapstain fungi

Creator:

Liu, Jiajian

Abstract:

The biocontrol potential of Trichoderma harzianum strains B-2A, B-8A, B-4B, B-15B, and B-41 and Serratia plymuthica was evaluated using agar plates and wood wafers of unseasoned ponderosa pine (Pinus ponderosa laws). All five isolates of Trichoderma harzianum and Serratia plymuthica could inhibit stain fungi growth in agar plates and exhibited...

Extraction of proteins from wood samples colonized by bioprotectants and/or stain fungi

Creator:

Cui, Li

Abstract:

Biological stain (blue stain) reduces wood value and prevents its use in many structural applications. Increasing environmental concerns have restricted the chemicals available for controlling this damage. As a result, biological control has received more interest. The application of these systems to wood has been limited due to their inability...
