Surface-enhanced Raman spectroscopy (SERS) is a powerful technique for identifying molecular species, but it has been primarily limited to noble metal supports. This study clarified the SERS mechanism based on semiconductor material - ZnO microtube in probing methylene blue (MB) as an equal contribution of charge transfer and SPR mechanisms.

A study on Mollusks’ species composition and distribution on dead coral from Quang Ngai to Cat Ba was conducted during the field survey between Vietnam and Russia on the AKADEMIC OPARIN RC vessel in 2021 at 39 reef stations in 14 study areas. By comparative morphology method, the authors have identified 135 taxa of Mollusca belonging to 48 families, 4 classes on coral reefs. The species composition of Mollusca was slightly different between study areas.

Isaria cicadae, currently identified as Paecilomyces cicadae (Miq.) Samson (Cordycipitaceae, Hypocreales, Ascomycetes), is a parasitic fungus on cicadas and is considered a folk medicine in traditional medicine. In this research, the antioxidant activity of some extracts from the biomass and fruit bodies of Isaria cicadae F0004 isolated in Vietnam was investigated.

The result pointed out that only 5 g of soft tissue from N. glans (equivalent to 2–3 specimens) containing maximum toxicity detected in the present study may cause human death if consumed. Fhe first time, this study identified TTXs in the gastropods as a causative toxin in the poisoning in Vietnam. Moreover, 65.5% of studied specimens with high toxicity higher than 100 MU/g, including 16.1%, showing extremely high toxicity (> 1,000 MU/g). The results suggested that this gastropod is quite dangerous for human consumption and should be alerted to public awareness.

Alpinia vietnamica H.Ð. Tran, Luu & Skornick was identified as a new species in 2019, which is widely distributed in Thua Thien Hue, Quang Nam, and Kon Tum provinces, Vietnam. The current study wishes to report phytochemical investigation, and the biological activities (cytotoxic, antioxidative, and α-glucosidase inhibitory) of isolated compounds.

This study utilized a non-destructive technique through quadrat sampling to identify and measure mangroves’ biodiversity and carbon stock. The allometric equation was applied to quantify the carbon stock and Shannon-Wiener diversity index to determine the biodiversity. Twelve species were identified from the 36 sampling plot with 10 × 10 meter.

The identification of most species relied on careful examination of their morphological characters. These findings collectively raised the Ophichthus genus’s representation in Vietnamese waters by introducing three previously undocumented species, raising the total count to 17 compared to prior research. Furthermore, this study provides a comprehensive key to aid in identifying the various Ophichthus species found in Vietnam.

This study compares the effectiveness of a digital and a paper-based dichotomous identification key for teaching pre-service teachers about plant species diversity. Twenty-four Slovenian teachers in pre-service training used a digital version of the key on tablet computers and twenty-nine used a paper-based version to identify woody species in the garden near their university faculty.

Da Xanh pomelo (Citrus maxima) is a fruit tree with many nutrients and high economic value. However, nematode attacks are one of the factors that limit productivity. The aim of this study was to investigate and identify the species composition of parasitic nematodes on Da Xanh pomelos tree in the study area, thereby assessing their prevalence and impact on the health and productivity of the pomelo trees.

Thuong Tien Nature reserve has high level of biodiversity. However, insect is one of the least study groups compared to other groups of animals in the reserve. In this study ant specimens were collected by using linetransect and point methods in Thuong Tien Nature reserve. Consequently, the researchers has initially identified 34 species of ants in 04 subfamilies (Dolichoderinae, Formicinae, Myrmicinae, and Ponerinae), and 23 genus. Of the 34 species, there are 10 ones that has been only determined for genus.

The present study aims to identify Neofusicoccum isolates collected from lotus with symptoms of dieback, blight, and wilted leaves. Species were identified based on their morphology and comparison of the DNA sequence data for ITS rDNA and β-tubulin (tub-2). The taxonomy and phylogenetic relationships of pathogen isolates were investigated, and their pathogenic abilities were determined.

In this study, a total of 30 yeast isolates were recovered from local fruits in Thua Thien Hue province. Genetic characterization based on the ITS sequences identified isolates belonging to 3 species including Saccharomyces cerevisiae, Lachancea fermentati, and Clavispora fructus, with high sequence homology (over 99%) compared to published sequences in the GenBank.

Ebook "Peptidomics: Methods and strategies" describes protocols for basic state-of-the-art approaches in the field of peptidomics. Most of these approaches are independent of the instruments used for analysis and can easily be adapted for equipment that is available in a typical proteomics facility. Chapters detail many of the basic techniques used to detect and identify peptides, methods for the relative quantitation of peptides between samples using isotopic labels or label-free approaches, and biological species as well as sample types.
