“…Without pyroligneous acid, the fermentation quality of the stylo and rice straw silage was low because of the relatively high pH. Organic acids, especially acetic acid, are the main components of pyroligneous acid ( Zhang Y. et al, 2020 ), which may partly explain the lower pH ( P < 0.05) and higher acetic acid content ( P < 0.05) in the present study in the pyroligneous acid-treated silages compared with those in the control silage. Plant cell respiration and microorganismal activities lead to nutrient losses during ensiling, especially in the early stages, and pyroligneous acid can decrease these losses possibly by direct acidification, which inhibits plant cell respiration and microbial activities.…”

“…The two fresh materials were mixed and chopped to 1–2 cm by hand with a paper cutter, then treated with 1% or 2% pyroligneous acid based on fresh matter. Pyroligneous acid was obtained from blended wood waste and filtered through a 0.45-μm cellulose acetate membrane, similar to that reported by Zhang Y. et al (2020) . Approximately, 100 g of silage materials were packed and compressed manually into plastic-film bags (12 bags per treatment), sealed with a vacuum sealer, and stored indoors at 27–32°C.…”

Influence of Pyroligneous Acid on Fermentation Parameters, CO2 Production and Bacterial Communities of Rice Straw and Stylo Silage

et al. 2021

Carbon dioxide (CO2) is a primary greenhouse gas and the main cause of global warming. Respiration from plant cells and microorganisms enables CO2 to be produced during ensiling, a method of moist forage preservation applied worldwide. However, limited information is available regarding CO2 emissions and mitigation during ensiling. Pyroligneous acid, a by-product of plant biomass pyrolysis, has a strong antibacterial capacity. To investigate CO2 production and the influence of pyroligneous acid, fresh stylo, and rice straw were ensiled with or without 1% or 2% pyroligneous acid. Dynamics of the fermentation characteristics, CO2 production, and bacterial communities during ensiling were analyzed. Pyroligneous acid increased the lactic acid content and decreased the weight losses, pH, ammonia-N content, butyric acid content, and coliform bacterial numbers (all P < 0.05). It also increased the relative abundance of Lactobacillus and decreased the relative abundances of harmful bacteria such as Enterobacter and Lachnoclostridium. Adding pyrolytic acids reduced the gas production, especially of CO2. It also increased the relative abundances of CO2-producing bacterial genera and of genera with the potential for CO2 fixation. In conclusion, adding pyroligneous acid improved the fermentation quality of the two silages. During ensiling, CO2 production was correlated with bacterial community alterations. Using pyroligneous acid altered the bacterial community to reduce CO2 production during ensiling. Given the large production and demand for silage worldwide, application of pyroligneous acid may be an effective method of mitigating global warming via CO2 emissions.

“…The relative proportion of humiclike components increased with increasing temperature, and the presence of humiclike substances may be related to the degradation of lignin and biomass materials [ 22 ]. PA is a by-product of gas condensation during pyrolysis in biochar production, involving complicated chemical components [ 23 , 24 ]. Moreover, PA contains phenolic substances with aromatic structures [ 25 ].…”

Effect of Pyrolysis Temperature on the Characterisation of Dissolved Organic Matter from Pyroligneous Acid

et al. 2021

Dissolved organic matter (DOM) greatly influences the transformation of nutrients and pollutants in the environment. To investigate the effects of pyrolysis temperatures on the composition and evolution of pyroligneous acid (PA)-derived DOM, DOM solutions extracted from a series of PA derived from eucalyptus at five pyrolysis temperature ranges (240–420 °C) were analysed with Fourier transform infrared spectroscopy, gas chromatography–mass spectroscopy, and fluorescence spectroscopy. Results showed that the dissolved organic carbon content sharply increased (p < 0.05) with an increase in pyrolysis temperature. Analysis of the dissolved organic matter composition showed that humic-acid-like substances (71.34–100%) dominated and other fluorescent components (i.e., fulvic-acid-like, soluble microbial by-products, and proteinlike substances) disappeared at high temperatures (>370 °C). The results of two-dimensional correlation spectroscopic analysis suggested that with increasing pyrolysis temperatures, the humic-acid-like substances became more sensitive than other fluorescent components. This study provides valuable information on the characteristic evolution of PA-derived DOM.

“…Biochar was produced from woody waste collected by a local furniture factory in a self-designed carbonization furnace at 450°C for 6 hours using slowly pyrolyzed, then air-dried and ground through a 2mm sieve. The pH and EC of biochar were 9.43 and 0.25 dS m -1 , respectively [11]. Fulvic acid was purchased from Shanghai Aladdin Biochemical Technology Co., Ltd. in 2017.…”

Biochar (BC) and fulvic acid (FA) have raised wide interest because of their multiple benefits in soil improvement. However, the difference between individual and co-application of biochar and fulvic acid on okra growth in salt-affected soils is unknown. In this study, a woody waste derived BC and a commercial FA were applied into a coastal salt-affected soil collected from the Yellow River Delta to investigate their effects on a commercial crop, okra (Abelmoschus esculentus) seedling growth following the individual and combined applications using a pot experiment. The results showed the individual and co-application of BC and FA increased the plant height, stem diameter and fresh biomass by 9.4–11.5%, 10.3–41.7% and 31.6– 40.0%, respectively, and individual application posed a better performance than co-application. Moreover, BC and FA individual and combined application could effectively improve the root growth of okra, whereas the individual application posed a greater effect. These findings would provide theoretical basis and technical support for developing green technologies for remediating degraded coastal wetland soils, thus ensuring sustainable agricultural development.
