“…Such behavior is attributed to the composition of the pyroligneous extract, which presents numerous compounds [15], which may have negative effects on the mycelium advancement on the culture medium, compounds that are not found in the P.A. alcohol, base of the hydroalcoholic solution.…”

“…An organic product resulting from the condensation of smoke expelled in the wood carbonization process, pyroligneous extract (also called wood vinegar) has been highlighted in recent years for its great potential for pest and disease control [15]. According to Yataga [16], the pyroligneous extract consists of phenolic components, acids, neutral components, alcohols and others, most of which are water (85%) and acetic acid (5.1%).…”

Fungi are the main microorganisms present in seeds, constituting the main cause of deterioration and production losses. Among the health testing methodologies for detecting fungi in seeds, incubation tests under controlled conditions facilitate fungal growth and sporulation. Therefore, this work aimed to evaluate the efficiency of pyroligneous extract in the control of phytopathogenic fungi occurring in Schizolobium amazonicum seeds. Treatments consisted of exposure of seeds to pyroligneous extract for a period of five minutes at concentrations (0%, 1%, 2.5%, 5%, 7%, 10% and 12.5%). The treated seeds were placed in Petri dishes, lined with two sheets of filter paper, moistened with sterile distilled water. The experimental design was completely randomized, consisting of 7 treatments, with 9 seeds per plate and 10 replications per treatment, totaling 630 seeds arranged in 7 Petri dishes. The evaluation was performed 8 days later, with the aid of stereoscopic and light microscopy, where the fungal growth in each seed in the plates was verified for the incidence calculation and then the identification of these. Pyroligneous extract was found to be efficient in reducing the fungal incidence of the genera Fusarium sp. and Rhizoctonia sp., fungi considered important plant pathogens that could compromise seed quality and seedling establishment in the field. It also reduced the incidence of storage fungi capable of causing seed deterioration and consequent loss of vigor, such as Aspergillus spp. occurring in seed samples of S. amazonicum. However, Penicillium sp was not controlled by treatment of S. amazonicum seeds with pyroligneous extract up to 12.5% concentration.

“…Due to its complex chemical composition and depending on its water concentration, WV has a wide range of applications, e.g., as pest repellents, plant growth promoters, plant fertilizers and additives for animal feed (Tiilikkala et al, 2010). Other uses of WV are as antifungal and antibacterial agents (Souza et al, 2012;Araújo et al, 2017;Souza et al, 2018;Yang et al, 2018) and as herbicides (Zeff erino et al, 2016).…”

Effect of Pyrolysis Heating Rate on the Chemical Composition of Wood Vinegar From Eucalyptus Urograndis and Mimosa Tenuiflora

et al. 2019

Among the parameters used in the biomass carbonization process, the heating rate is one of the most important. The objective of the present work was to assess the influence of different heating rates on the chemical composition of wood vinegar (WV) from two wood species. Dried disks of Eucalyptus grandis and Mimosa tenuiflora wood were used as raw material. Carbonization runs were carried out in a laboratory muffle furnace at three heating rates (0.7, 1.0 and 1.4 °C/min), with 10 runs at each heating rate, reaching 450 °C. Yields of charcoal, pyrolysis liquids and gases were determined for all carbonization conditions. Crude pyrolysis liquid from each wood species and each heating rate was bi-distilled, yielding purified WV samples. These samples were extracted with ethyl acetate and the organic fraction was analyzed by gas chromatography-mass spectrometry to obtain qualitative and semi-quantitative data. Results showed that lower heating rates produce higher yields of charcoal, while higher heating rates lead to higher yields of pyrolysis liquids and gases. Totals of 57 and 42 chemical compounds were identified in the WV of Eucalyptus and Mimosa, respectively, divided into the following groups: alcohols, ketones, furans and pyrans, and phenolic compounds. In general, higher heating rates led to greater contents of furans and pyrans and lower concentrations of phenolic compounds.

“…A temperatura utilizada na pirólise afetará a composição química específica desses subprodutos, ou seja, licores pirolenhosos obtidos a diferentes temperaturas terão composição química similar, porém diferentes entre si. Considera-se que a presença de compostos fenólicos e seus derivados seja o principal fator conferindo atividades antifúngica, antimicrobiana e antioxidante (BRAGE e SJÖSTRÖM, 1991;JANKOWSKY e LEPAGE, 1986;LOO;JAIN e DARAH, 2008;SOUZA et al, 2018; THEAPPARAT; PONGLIMANONT e CHANDUMPAI, ZHAO et al, 2017).…”
