“…It further transforms to the small amount of furans and acids through fission and disproportionation (Zhang et al 2013). A high yield of LG was obtained at 550 °C, demonstrating its high thermal stability (Lian et al 2010). The relative contents of the compounds identified were measured from their peak areas and expressed as percentages (Table 1).…”

Levoglucosan (LG) obtained from lignocellulosic biomass exhibits great potential as a specific tracer for biomass burning aerosols and as a raw material for synthesizing stereoregular polysaccharides. One potentially viable source of LG is pyroligneous acid (PA). This study investigated the effects of heating temperature on the extraction capability and the chemical composition of distillate and residual fractions. The results demonstrated that vacuum distillation extracted the acids, alcohols, ketones, aldehydes, and other organic matter. When the heating temperature was above 80 °C, the moisture content of the residual fraction was unchanged. The chemical composition of residual fraction was analyzed by gas chromatography-mass spectrometry (GC-MS). The analysis showed that the relative content of the LG, as obtained from the 90 °C distillation temperature, was 75.6%. Thus, it can be used as raw material for subsequent purification.

“…Centrifugation is a simple pretreatment technique, but there are some limitations on the separation of the homogeneous PA (Lian et al 2010). Liquid chromatography effectively separates aromatic and saturated hydrocarbons, but there is the problem of high solvent consumption and cost (Chi et al 2013).…”

“…Major detoxification processes reported for bio-oil include solvent extraction, adsorption on activated carbon, and over-liming (Lian et al 2010;Chan and Duff 2010) ( Table 2). Another approach of the pre-treatment strategy is to collect the bio-oil in distinct fractions and use the fraction(s) rich in substrates but depleted in inhibitory contaminants (Westerhof et al 2011;Pollard et al 2011) (Figure 2).…”

“…While current research efforts can utilize existing toxicity data, results from Lian et al suggest that some of the most toxic bio-oil components are those with little available toxicity data, such as eugenol, acetol and vanillin (Lian et al 2010). Thus, additional studies of these compounds could be beneficial for improving bio-oil utilization.…”

Thermochemical processing of biomass by fast pyrolysis provides a nonenzymatic route for depolymerization of biomass into sugars that can be used for the biological production of fuels and chemicals. Fermentative utilization of this bio-oil faces two formidable challenges. First is the fact that most bio-oil-associated sugars are present in the anhydrous form. Metabolic engineering has enabled utilization of the main anhydrosugar, levoglucosan, in workhorse biocatalysts. The second challenge is the fact that bio-oil is rich in microbial inhibitors. Collection of bio-oil in distinct fractions, detoxification of bio-oil prior to fermentation, and increased robustness of the biocatalyst have all proven effective methods for addressing this inhibition.

“…In previous researches phenol biodegradation was determined at relatively less toxic conditions (~200 mg/L) and kinetic parameters were not reported [19]. For the industrial uses of R. glutinis phenol is removed from the supernatant to eliminate its toxic effect [20]. This species is not known as a phenol degrading microorganism.…”

Biotoxicity and low temperature are among the challenges of biodegradation as well as microbial transport in in-situ bioremediation applications. This study investigates the effect of low temperature, high and low concentrations of phenol, on biodegradability and the surface properties of Rhodotorula glutinis which may be instrumental to develop control mechanisms in engineering applications. Results showed that Rhodotorula glutinis is able to grow at low phenol (< 0.5 g/L) and glucose (1.0 g/L) concentrations. Microbial growth rates of Rhodotorula glutinis is the highest at 25°C for phenol fed reactors. Temperature and type of carbon source affected the total amount of extracellular polymeric substances (EPS) and the relative amounts of EPS constituents. Phenol fed Rhodotorula glutinis, at 4°C, were found to be hydrophobic whereas Rhodotorula glutinis showed less hydrophobic characteristics at 25°C, regardless of the carbon source. Surface hydrophobicity of Rhodotorula glutinis is related to the distribution of carbohydrate and proteins in the EPS.
