Summary: This study investigated the insecticidal and acaricidal activities of a mixture containing three Cratylia mollis seed lectins against the termite Nasutitermes corniger and the mite Tetranychus bastosi. The results showed that the mixture had significant insecticidal and acaricidal effects against both pests. Additionally, the mixture also reduced the reproductive rate of the mite.

Summary: This study investigates the insecticidal activity of essential oil from Lippia alba leaves collected at Caatinga and its major compound against termite Nasutitermes corniger and maize weevil Sitophilus zeamais. The essential oil promoted the mortality of N. corniger and showed antinutritional effects against S. zeamais. 1,8-cineole had termiticidal effects on N. corniger workers and fumigant effects against S. zeamais.

Summary: This study analyzed the chemical composition and antifungal activity of the essential oil extracted from the Hymenaea stigonocarpa fruit peel. The oil showed antifungal activity against Botrytis cinerea, Sclerotinia sclerotiorum, Aspergillus flavus and Colletotrichum truncatum. The main constituents of the oil were spathulenol and caryophyllene oxide. This study is the first to describe the chemical composition and antifungal activity of this essential oil against B. cinerea and C. truncatum.

Summary: The ethanolic extract from Anadenanthera colubrina leaves showed high antioxidant and anti-inflammatory activities, likely due to its high content of phenolic compounds. In vitro and in vivo experiments demonstrated that EEAc inhibited nitric oxide and TNF-alpha production, while maintaining high cell viability.

Summary: This study provides a checklist of Leguminosae from Chapada das Mesas National Park in Maranhao, Brazil, contributing to the botanical knowledge of the area. It records 62 genera and 158 species, including several endemic species to Brazil. The data presented here expand our understanding of Leguminosae in Maranhao and Cerrado and highlight the need for conservation efforts in the face of environmental degradation.

Summary: This study presents an updated checklist of angiosperms from the Inhamum Municipal Environmental Protection Area (IMEPA) in Caxias, Maranhao, Brazil. The data provides information on the most representative taxa, number of collections, occurrence patterns, and endemicity of the species. The analysis also reveals the floristic similarity between IMEPA and other Cerrado areas in the state. The study contributes to filling the biodiversity gaps in Northern Brazil and expanding the understanding of the Cerrado flora in Maranhao.

Summary: Bacteria generate and release extracellular reactive oxygen species (eROS), which significantly contribute to the natural ROS pool and play a crucial role in metabolic interactions of bacteria with their environment. Understanding the behavior of eROS-generating bacteria and its environmental implications is of great importance in the cycling of biogeochemical elements, transformation of organic matter, and regulation of antibiotic resistance genes.

Summary: Plastics and microplastics are widely present and accumulating in the environment, leading to increasing public attention. In addition to packaging plastics, materials from industries such as electronics, space and aviation are also accumulating, but receiving less attention. The production of degradable and biodegradable plastics is seen as a way to reduce environmental impacts, but enhancing the non-degradability of functional polymers is also a feasible option. Microbial colonization and deterioration pose significant challenges to these materials.

Summary: This study evaluated the keratinolytic activity of 37 strains of Trichophyton ajelloi and found that pigmented strains isolated from loamy soil were more efficient in degrading native feather keratin, while non-pigmented strains isolated from chernozem showed better abilities. The keratinolytic activity increased over time, as evidenced by the increase in extracellular keratinase activity and release of soluble proteins and peptides. Protease activity peaked in the first 7 days and again on day 28 of culture. The release of ammonium and sulfate ions, associated with an increase in pH, reached its maximum on day 21. Three pigment-producing strains were among the most active in releasing large amounts of ammonium and sulfate ions. The biodegradation of feather waste by Trichophyton ajelloi strains can be used to produce fertilizers suitable for plants with high sulfur requirements.

Summary: The incomplete recycle of residual mulch film (RMF) in recent years has led to an increase in plastic fragments in soil, posing a serious threat to the soil ecological environment. In this study, seven potential plastic-degrading microorganisms were screened and identified from film-mulched vegetable fields. The degradation ability experiments showed that both single strains and mixed strains demonstrated varying levels of degradation of RMF.

Summary: This study investigated the degradation of heat-treated wood by brown rot fungi and found that the decay increased the hygroscopicity of wood in the decaying state. Furthermore, it was observed that heat-treated samples were more susceptible to fungal decay compared to untreated samples, which may be related to the increase in moisture content.

Summary: This study investigated the phenomenon of Centimetric circular areas Uncolonized by Microbial Biofilms (CUMBs) on natural and heritage stone surfaces. The analysis revealed a compatibility in distribution and size between CUMBs and lichen thalli, suggesting a lichen origin for some CUMBs. Microscopic analysis also showed similar modifications in marble layers beneath CUMBs and lichens, indicating a possible alteration of stone properties by lichens.
