Decrypting seasonal patterns of key pollen taxa in cool temperate Australia: A multi-barcode metabarcoding analysis
Environ Res. 2023 Dec 1:117808. doi: 10.1016/j.envres.2023.117808. Online ahead of print.ABSTRACTPollen allergies pose a considerable global public health concern. Allergy risk can vary significantly within plant families, yet some key pollen allergens can only be identified to family level by current optical methods. Pollen information with greater taxonomic resolution is therefore required to best support allergy prevention and self-management. We used environmental DNA (eDNA) metabarcoding to deepen taxonomic insights into the seasonal composition of airborne pollen in cool temperate Australia, a region with high rates ...

Immunotoxicological, histopathological, and ultrastructural effects of waterborne pyrogallol exposure on African catfish (Clariasgariepinus)
Chemosphere. 2023 Nov 26:140792. doi: 10.1016/j.chemosphere.2023.140792. Online ahead of print.ABSTRACTPyrogallol is a naturally occurring polyphenol derived from natural plants, such as Acer rubrum and Eucalyptus sp. The current study was designed to evaluated pyrogallol-mediated toxicity at sublethal levels (1, 5, and 10 mg/L), derived from 96 h-LC50 values previously determined for African catfish (Clarias gariepinus). Immunotoxicological indices, histological, histochemical, and ultrastructural alterations in C. gariepinus were evaluated following a 15-day pyrogallol exposure. Pyrogallol decreased immune parameters [ly...

Impact of Eucalyptus residue leaching on iron distribution in reservoir sediments assessed by high-resolution DGT technique
In this study, two experiments were conducted to simulate the early decomposition processes of exotic Eucalyptus and native Pinus massoniana leaves in water (LW) and water-sediment (LWS) systems. In LW, high concentrations of tannic acid (>45.25 mg/L) rapidly leached from the Eucalyptus leaves to the water column, exceeding those of Pinus massoniana leaves (<1.80 mg/L). The chrominance increased from 5~10 to 80~140, and the water body finally appeared brown instead of black after the leaching of Eucalyptus leaves. The chrominance positively correlated with tannic acid concentrations (R=0.970, p<0.01), indicating t...

Reduction of methane and nitrogen emission and improvement of feed efficiency, rumen fermentation, and milk production through strategic supplementation of eucalyptus (Eucalyptus citriodora) leaf meal in the diet of lactating buffalo (Bubalus bubalis)
Environ Sci Pollut Res Int. 2023 Nov 24. doi: 10.1007/s11356-023-31089-0. Online ahead of print.ABSTRACTBuffalo plays a compelling role in reducing malnutrition and ensuring food to the people of Asian countries by its major contribution to milk and meat pool of the livestock agriculture farming system in the region. As Asia is the home for more than 90% of world buffalo population, they are also one of the largest emitters of greenhouse gasses. Eucalyptus (Eucalyptus sp.) leaves are rich sources of naturally occurring essential oils and phenolic compounds, which could modulate rumen fermentation through mitigation of meth...

Eucalyptus-derived essential oils alleviate microbes and modulate inflammation by suppressing superoxide and elastase release
The Eucalyptus tree, belonging to the myrtle family, grows all over the world for its pharmaceutical and industrial benefits. In this article, we present a comparative analysis of the chemical composition of the hydrodistilled oils obtained from three different Eucalyptus species growing in Egypt viz. E. citriodora, E. camaldulensis, and E. ficifolia. Gas Chromatography-Mass Spectrometric guided analysis resulted in the identification of a total of 20 metabolites in E. citriodora oil with citronellal (54.9%) and citronellol (25.4%) being the most dominant components. β-cymene (12.7%) and 1,8-cineole (11.7%) were the major...

A preliminary metabarcoding analysis of Portuguese raw honeys
Arch Microbiol. 2023 Nov 20;205(12):386. doi: 10.1007/s00203-023-03725-3.ABSTRACTThe microbial diversity in Portuguese raw honeys remains largely uncharacterized, constituting a serious knowledge gap in one of the country's most important resources. This work provides an initial investigation with amplicon metabarcoding analysis of two Lavandula spp. from different geographical regions of Portugal and one Eucalyptus spp. honey. The results obtained allowed to identify that each honey harbors diverse microbiomes with taxa that can potentially affect bee and human health, cause spoilage, and highlight bad bee-hive management...
