The effectiveness of three kinds of enzymes (chitinase, β-glucuronidase, and lysing enzyme complex), employed as elicitors to enhance the β-glucan content in the sawdust-based cultivation of cauliflower mushroom (Sparassis latifolia), was examined. The elicitors were applied to the cauliflower mushroom after primordium formation, by spraying the enzyme solutions at three different levels on the...

This study investigated catalytic microwave pyrolysis of Douglas fir sawdust pellets using carbon catalysts produced from corn stover. The effects of catalyst to biomass ratio on the bio-oil, syngas, and biochar yields were determined. Functional groups (carbonyls, phenolics, lactones, carboxyls) of carbon catalysts and GC/MS analysis were used to study the catalytic pyrolysis of Douglas fir sa...

Do we say dog when we say hotdog? In five experiments using the implicit priming paradigm, we assessed whether nominal compounds composed of two free morphemes like sawdust or fishbowl are prepared for production at the segmental level in the same way that two-syllable monomorphemic words (e.g. bandit) are, or instead as sequences of separable words (e.g. full bowl or grey dust). The experiment...

Nowadays, ca. 176,640 tons/year of silicon (Si) (>4N) is manufactured for Si wafers used for semiconductor industry. The production of the highly pure Si wafers inevitably includes very high-temperature steps at 1400-2000 °C, which is energy-consuming and environmentally unfriendly. Inefficiently, ca. 45-55% of such costly Si is lost simply as sawdust in the cutting process. In this work, we de...

Petroleum refining industries produce large amounts of toxic effluents, causing environmental pollution. Iran is an oil-rich country that encounters oil pollution in its soil and water. Bioremediation of these pollutants is an appropriate solution to tackle them, compared to physical and chemical remediation methods. There are some factors that increase the rate of biodegradation; therefore, th...

background lead is a toxic metal with a poor electrical conductivity. this metal can be hazardous and poisonous even in low concentrations. objectives the objective of this study is the evaluation of prosopis mimosaceae sawdust as a low-cost adsorbent for removal of the lead from effluents. materials and methods the experiment was conducted in a batch system and the effect of ph, the amount of ...

In this piece, Barbara Adler reflects on the Vancouver arts collective known as Sawdust Collector, which ceased operations during pandemic. She asks how we might move beyond exhaustion by allowing ourselves time to slow down and space reimagine creative praxes, contributing our energies unfinished work of others.

Pine sawdust (9 kg m−2) was ploughed into soils, intended for future forestry plantations, that had been left for 3 or 6 years after previously being used for agriculture. Two years after the amendment, soil pH had changed in both sites and the C:N ratio had increased. Total fungal populations decreased after the treatment. A small decrease in the number of species was not statistically signifi...

In the present study, sawdust bio-oil (SBO) manufactured by fast pyrolysis of Japanese red pine (Pinus densiflora Siebold and Zucc.) sawdust was analyzed for its volatile chemical compound composition and evaluated for its free radical scavenging potential, inhibition of lipid peroxidation and reducing power. Gas chromatography and mass spectroscopy revealed 29 volatile compounds, comprising 97...
