Green coconut (Cocos nucifera L. var. dwarf) is one of the most cultivated commodities on the Brazilian coast. Most green coconut waste is burned or disposed of as garbage on coconut-producing properties, on the streets of large cities, and in landfills. Incorrect disposal of coconut waste causes several problems as proliferation of disease vectors, occupation of large areas in landfills, production of gases, and contamination of soil and groundwater. The conversion of this biomass can be carried out through pyrolysis. The bio-oil from the pyrolytic process has a complex chromatographic profile requiring a fractionation step to improve its separation and characterization. In this work, the bio-oil was fractionated according to its acidity (strongly acidic, slightly acidic, basic, and neutral), and both the bio-oil and the fractions were analyzed by fast-GC × GC/TOFMS. The fractionation process used was able to reduce the complexity of the generated crude bio-oil. Three hundred and five different compounds were identified between the fractions analyzed and the crude bio-oil. The time for each analysis was 19 min, demonstrating the gain of the separation/detection technique without losing quality in the identification. The majority of the compounds in the fractions were phenol, catechols, eugenols, and furfural, reinforcing the idea of using this bio-oil as a precursor in the chemical industry.

“…Based on Table 2, this compound has been reported in baijiu and sugar-beet vinasses. The eugenol (4-allyl-2-methoxyphenol) found in tequila vinasse (Table 2); it is an acaricidal agent, having fungicidal and bactericidal activities (Abd El-Baky and Hashem 2016; Shang et al 2020). Oleuropein shows bactericidal and fungicidal activities, mainly contained in olives (Bisignano et al 1999), and, as shown in Table 2, was also in the wastewater.…”

Pests have a negative impact on the economy and the environment. There is an increased urgency for adequate pest control because many pests show high adaptation and climate change has created favorable circumstances for pests. For pest control, synthetic chemicals are used that are lethal to non-target organisms and are toxic to pollinators and aquatic invertebrates. Chemical compounds in plants and derivatives from lignocellulosic materials act against pests. The wastewater from lignocellulosic biomass is a potential source of new compounds with bactericidal, fungicidal, and pesticidal effects that have demonstrated inhibitory activity against plant pathogens. Fungicidal, nematicidal, insecticidal, larvicidal, and bactericidal activities have been proven. Inorganic and organic compounds, such as phenols, aldehydes, esters, and furanics, are the main ones identified. Due to the antimicrobial activity of wastewater, applying it to the soil can modify the composition and structure of key microbial communities. Deep research about richness, biodiversity, functionality, and microbials is needed. This review provides a comprehensive overview of wastewater types that have been applied and possible sources to obtain potential compounds for pest control. Moreover, associated active compounds, recovery techniques, and environmental impacts are reviewed.

Plants have been used by humans since ancient times due their antimicrobial and medicinal properties. Essential oils (EOs) are complex mixtures of secondary plant metabolites, including terpenoids, phenylpropanoids, and other aromatic compounds. Cinnamomun verum and Thyme vulgaris EOs and their organic extracts exert numerous biological activities because of their major compounds, particularly thymol, carvacrol, eugenol, and benzoic and cinnamic acid. The structural motifs presented by these phytochemicals are responsible for their biological activities. Modification or hybridization of these structures could lead to new bio-based compounds with improved efficacy or multiple modes of action. In this work, we aimed to develop reliable methods of obtaining six hybrid molecules from the major constituents of C. verum and T. vulgaris EOs. For the first time, we tested their efficacy in the inhibition of the mycelium growth and spore germination of two of the most important phytopathogenic fungi, Fusarium oxysporum and Colletotrichum gloeosporioides, and one opportunistic human pathogen, Aspergillus niger. The cytotoxic activity of the obtained hybrids was assessed using the brine shrimp lethality assay. In addition, we report for the first time a biocatalytic process for the obtention of these bioactive hybrid molecules. The results of this work enable the possibility of using hybrid molecules based on the major constituents of EOs as active ingredients in strategic industries such as agriculture, aquaculture, and pharmaceuticals.
