Evaluation of wood treated with copper-based preservatives for Cu loss during exposure to heat and copper-tolerant Bacillus licheniformis
1999 - IRG/WP 99-20155
…autoclave conditions and the copper-tolerant bacterium, Bacillus licheniformis CC01, for 10 d at 28°C and 150 rpm. Sixteen to 37 percent of the copper was released from the wood during autoclaving, with copper citrate demonstrating the highest percent loss. Forty-four to 82 percent of the copper remaining in the…

Enhanced removal of CCA from treated wood by Bacillus licheniformis in continuous culture
1997 - IRG/WP 97-50083
…this organism, which has been presumptively identified as Bacillus licheniformis. Analysis of the sawdust by atomic absorption spectroscopy revealed 80% reduction in copper and 43% reduction in arsenic when the sawdust was exposed to B. licheniformis in a standard mixed culture for 10 d compared to an untreated…

Integrated protection of freshly sawn lumber using Bacillus subtilis and selected fungicide
1997 - IRG/WP 97-10235
…on Pinus ponderosa sapwood under laboratory conditions. Bacillus subtilis provided poor control of discoloration. The addition of fungicide produced no enhancement of bioprotection. Evaluation of bacterial cultures containing this fungicide indicated that the chemicals had a profound effect on bacterial filters.

Semi-Solid State Bioremediation of CCA-Treated Wood Using Malted Barley as a Nutrient Source
2002 - IRG/WP 02-50184
…oxalic acid extraction and the metal-tolerant bacterium Bacillus licheniformis, 70-100% of the copper, chromium and arsenic can be removed from CCA-treated SYP, but the liquid culture medium used to support the bacterial growth renders this process costly. Processing costs could be partially offset if the culture…

Effect of remediation on the release of copper, chromium, and arsenic from particleboard made from CCA treated wood
2001 - IRG/WP 01-50170
…effect of remediation with oxalic acid (OA) extraction and Bacillus licheniformis fermentation on the release of copper, chromium, and arsenic from particleboard made from remediated wood particles and also investigates durability of the particleboard against white and brown- rot fungi. Particleboard samples were…

Properties of particleboard made from recycled CCA-treated wood
2000 - IRG/WP 00-50146
…wood ultimately come out of service. Bioleaching with Bacillus licheniformis CC01 and oxalic acid extraction are two methods known to remove significant quantities of metals from CCA-treated wood. Remediated particulate CCA-treated southern pine was reassembled into particleboard (PB) using 10% urea-formaldehyde…

CCA removal from treated wood by chemical, mechanical and microbial processing
1998 - IRG/WP 98-50101-26
…bacterial fermentation. Exposing CCA-treated sawdust to Bacillus licheniformis CC01 resulted in 91%, 15% and 45% removal of Cu (as CuO), Cr (as CrO3), and As (as As2O5), respectively. Eighty-one percent CuO, 62% CrO3, and 89% As2O5 was removed from CCA-treated sawdust by oxalic acid extraction alone. Combining…

Effect of Rifampin on gut symbiotic bacteria isolated from Anacanthotermes vagans Hagen (Isoptera: Hodotermitidae)
2014 - IRG 14-10835
…species, Enterobacter cloacae, Rhodococcus sp. and Bacillus subtilis were sensitive to the action of this antibiotic, whereas Klebsiella pneumonia, Enterobacter aerogenes, Enterobacter sp., Klebsiella oxytoca, Klebsiella sp., Corynebacterium sp., and Staphylococcus lentus were less affected by this antibiotic.

Development of microbiological test methods for the wooden packaging of foodstuffs
2010 - IRG/WP 10-20453
…step, poplar specimens were artificially contaminated with Bacillus stearothermophilus, Micrococcus luteus and Penicillium expansum. Then, we applied current sampling methods such as agar-contact plates, stomacher and ultrasonic sound and compared their efficiency. The results showed that only very low rates of…

Studies on the Toxicity of IPBC and Other Biocides to Bacteria
2004 - IRG/WP 04-10544
…Stenotrophomonas, Actinomycetes, Alcaligenes and Bacillus. Of these, only the last group was largely incapable of the dehalogenation of IPBC. Six representative strains were chosen for further study, and the ability of these six bacteria to degrade IPBC was elucidated. The Bacillus and actinomycete were…

…bolts were almost Gramnegative rods and scarcely isolated Bacillus spp. that has been thought to be one of the most effective species to change pit structures so far. Starch granules in parenchyma cells in sapwood and intermediate wood were disappeared after the water-storage for 4 weeks. After that degradation of…

Effect of nutrient regimes, temperature, pH, and wood sterilization method on performance of selected bioprotectants against wood staining fungi
1992 - IRG/WP 92-1551
…bioprotectants (Pseudomonas putida, Pseudomonas cepacia, Bacillus subtilis, and Trichoderma harzianum) against wood staining fungi were evaluated using small ponderosa pine samples over a four week period. Incubation at 32°C resulted in slight increases in the degree of fungal stain, but the results were not…
