“…These acids are then decarboxylated to generate vinyl phenol, vinyl guaiacol, and vinyl catechol through the phenolic acid decarboxylase. Their further reduction generated ethyl phenol, ethyl guaiacol, and ethyl catechol [52] that showed insecticidal activity against mosquitoes, flies, and aphids [58][59][60]. Ethyl phenol and ethyl guaiacol had a lethal dose LD90 of 134 and 455 µg/larvae, respectively, on the 4th instar larvae of Spodoptera littoralis, while their antifeedant property was 100% with 250 µg/cm 2 in both compounds [61].…”

Currently, insect pest control is carried out through the application of synthetic insecticides which have been related to harmful effects on both human and environmental health, as well as to the development of resistant pest populations. In this context, the development of new and natural insecticides is necessary. Agricultural and forestry waste or by-products are very low-cost substrates that can be converted by microorganisms into useful value-added bioactive products through fermentation processes. In this review we discuss recent discoveries of compounds obtained from fermented substrates along with their insecticidal, antifeedant, and repellent activities. Fermentation products obtained from agricultural and forestry waste are described in detail. The fermentation of the pure secondary metabolite such as terpenes and phenols is also included.

“…Another challenge for the pyrolysis gasification of bamboo is the utilization of tar in the liquid byproducts [17]. As bamboo-derived tar (BT) contains polycyclic aromatic hydrocarbons, phenols, as well as other aromatic and nonaromatic organic compounds [18,19], it is difficult to make large-scale and high-value use of this complex BT [20][21][22].…”

The effective utilization of charcoal and tar byproducts is a challenge for pyrolysis gasification of bamboo. Herein, the bamboo tar was modified via polymerization and acted as a new adhesive for the preparation of excellent bamboo-charcoal-derived molding activated carbon (MBAC). As compared with pristine tar and other adhesives, the aromatization of tar with phenol increased its molecular weight, oxygenic functional groups, and thermal stability, leading to the decreased blocking impact of charcoal pore and improved bonding and pyrolytic crosslinking effect between charcoal particles. These further contribute to the high mechanical strength, specific surface area, pore volume, and amount of oxygenic functional groups for fabricated MBAC. Owing to the high microporous volume of MBAC, it exhibited 385 mg·g−1 toluene and 75.2% tetrachloride gas adsorption performances. Moreover, the pseudo-first-order, pseudo-second-order, and Bangham models were used to evaluate the kinetic data. The toluene adsorption process conforms to the Bangham kinetic model, suggesting that the diffusion mechanism of toluene adsorption mainly followed intraparticle diffusion.
