“…Accordingly, the decreased hardness in the untreated wood after deterioration caused by fungal attacks was mainly related to hemicellulose loss, which affected the integrity of the cell wall polymers and, consequently, decreased the strength against mechanical loads (Bari et al, 2015).…”

“…Similarly, Bari et al (2015) attributed the 1223 cm -1 peak emergence to the lignin syringyl ring, which refers to the C-O stretching between lignin and xylose. The 1220 and 1110 cm -1 bands featured vibrational stretching of many lignin and carbohydrate groups (Poletto et al, 2012), which showed that lignin-hemicellulose bonds were cleaved during biological deterioration.…”

“…The fungal attack led to the emergence of peaks, as well as to the reduction and displacement of others, which, according to Bari et al (2015), results from enzyme action.…”

“…After fungal attack, the wood presents mass reduction, reduced compressive strength parallel to the fibers, as well as reduced impact strength, hardness, static flexion, and esthetic pattern modifications, which compromises the material's useful life (Stangerlin et al, 2013;Bari et al, 2015;Witomski et al, 2016) and versatility.…”

Resistance of TiO2-treated Eucalyptus botryoides Wood to the Fungus Ganoderma applanatum

et al. 2018

The aim of the present study is to investigate the resistance of Eucalyptus botryoides treated with TiO 2 particles to attack by the fungus Ganoderma applanatum. The Bethel treatment method was applied to wood specimens (25 × 25 × 9 mm) and compared to CCB. The wood was subjected to the accelerated decay test and characterized through Rockwell Hardness and Fourier Transform Infrared Spectroscopy (FT-IR). The TiO 2 -treated wood showed lower degradation and greater resistance to the penetration of a steel sphere (Rockwell Hardness) than the untreated wood. In addition, the results of the TiO 2 treatment were statistically equal to those of CCB. The FT-IR analysis showed that the fungus degraded lignin and hemicellulose in untreated samples. The present results showed the TiO 2 efficiency in forming a protective layer on the cell wall and in preventing the development of microorganisms, a fact that verifies its fungicidal action on wood.

“…5a); therefore, the range of thermal degradation of cellulose (George et al 2014) was affected starting at this stage, probably due to the decrease in the amount of cellulose as colonization time progressed (Table 1). T. versicolor, from a certain point in the colonization period, aggressively degraded not only lignin and hemicellulose but cellulose as well, as its action was not selective upon lignin, thus decreasing the cellulose content and rendering the material less thermally stable (George et al 2014;Bari et al 2015). This behavior was nevertheless not so noticeable in pulp generated by P. ostreatus, for which variation of the mass at maximum decomposition was almost constant (Fig.…”

Biopulp from Pineapple Leaf Fiber Produced by Colonization with Two White-Rot Fungi: Trametes versicolor and Pleurotus ostreatus

et al. 2016

Trametes versicolor and Pleurotus ostreatus were used for the biopulping from pineapple leaf fiber (PALF). PALF substrate was subjected to T. versicolor for 2 to 6 weeks and to P. ostreatus for 4 to 8 weeks. The yields, holocellulose and lignin contents, and extractives in ethanol-toluene mixture and in sodium hydroxide (NaOH) solution were evaluated. Fourier transform infrared spectroscopy (FTIR) spectra, thermogravimetric analysis (TGA), and color studies by L*a*b* systems were used for sample analysis. The results showed that the pulp yield was 55% to 70% with P. ostreatus and 35% to 50% with T. versicolor. Longer colonization periods increased the amount of holocellulose and decreased the amount of lignin and extractives in ethanol-toluene and NaOH solution. TGA showed an increase in intensity associated with cellulose, and the observed inflexion was attributed to lignin, which showed a tendency to fade. The FTIR spectrum showed high intensity between 3100 cm -1 and 3600 cm -1(cellulose) and decreased intensity at 1730 cm -1 (lignin). For both fungi, the pulp color produced an increase in L* color parameter and decreased in yellowness, while little variation was observed in redness. The most appropriate colonization period was 5 weeks for P. ostreatus and 4 weeks for T. versicolor.
