Kaempferia L. is a genus belonging to Zingiberaceae family, with many species used in indigenous medicines Asian countries. champasakensis Picheans. and Koonterm. are rare found only Laos Vietnam. The aim of this study was provide the micro-morphological traits volatile compounds acetone extract isolated from K. for first time. Using gas chromatography/mass spectrometry (GC/MS) assay, twenty-three components were identified studied extract, among which tyranton (22.41%), 9(E),...
This study investigated the potential of cellulose-degrading microorganisms for treating agricultural by-products, specifically spent mushroom substrate (SMS). From a pile SMS, 48 thermotolerant microbes were isolated, comprising 24 bacterial strains, 20 actinomycete strains and 4 mold strains. Following cellulase production co-culture compatibility screening, seven selected further analysis. Phylogenetic analysis based on 16S rRNA ITS sequences identified three (DVK16, DVK27, DVK33) as...
This study presents the comprehensive analysis of chemical composition and biological activities methanol ethanol extracts from Humphreya endertii, a recently discovered mushroom species in Vietnam. Gas chromatography/mass spectrometry identified 16 compounds extract 20 extract, with significant differences between two. The contained 18.51% 5-Methoxypyrrolidin-2-one, 15.41% cis-Vaccenic acid, 14.03% 10(E),12(Z)-Conjugated linoleic 13.95% n-Hexadecanoic 8.25% 2,5-Furandione,...
Abstract Although most studies have indicated that biochar can boost rice ( Oryza sativa ) growth, the material may also suppress it, depending on ratios of carbon (C) to nitrogen (N) and available N phosphorous (P). The current study sought examine impacts growth identify underlying mechanisms. A pot experiment was conducted using two soils high (3.05%) low (0.54%) organic (OC) content, mixed with 0, 1.5, 3, 6, 12% planted rice. Rice components, five tissue nutrients, nine soil properties...

This study is devoted to the synthesis of King Orange peel essential oil in water nanoemulsions combined with nanosilver by ultrasonic method supported mechanical stirring for antibacterial application. The samples were characterized Gas chromatography-mass spectrometry (GC-MS), Ultraviolet–visible (UV-Vis), Transmission electron microscopy (TEM), and Dynamic light scattering (DLS) methods. According above-experimental results, it was found that emulsions based on orange (without nanosilver)...
Curcuma thorelii Gagnep. and cotuana Luu, Škorni?k. & H.?.Tr?n are the rare species only found in Southeast Asia. The present study was first to explore chemical compositions antibacterial effects of whole plant acetone extracts these 2 species. Altogether 41 31 compounds have been identified C. by gas chromatography/mass spectrometry. Accordingly, extract contained (E)-labda-8(17),12-diene-15,16-dial (33.37%), vitamin E (12.33%), phytol (9.83%) as major while predominantly (14.58%),...
Xanthomonas oryzae pv. (Xoo) is a plant bacterial pathogen that causes blight (BB) disease, resulting in serious production losses of rice. The crystal structure malonyl CoA-acyl carrier protein transacylase (XoMCAT), encoded by the gene fabD (Xoo0880) from Xoo, was determined at 2.3 Å resolution complex with N-cyclohexyl-2-aminoethansulfonic acid. Malonyl transfers group CoA to acyl (ACP). transacylation step essential fatty acid synthesis. Based on rationale, XoMCAT has been considered as...
Terminalia catappa is a widespread medium tree species in many tropical countries. While the majority of studies up to date focuses on aerial part plant such as leaf, stem bark and fruit, information about phytochemical property well biological edible seed still scarce. This study was first explore fatty acid composition, antibacterial antioxidant activities oil from T. grown Vietnam. The results showed that both hot-pressed cold-pressed oils contained high level unsaturated acids oleic...
Dragon fruit or pitahaya (Hylocereus spp.) are famous for their nutrient-rich favourable taste, which brings high economic value to subtropical and tropical countries. However, dragon cultivation all over the world is threatened by fungal pathogens among them, Neoscytalidium dimidiatum has recently been shown be responsible stem canker rot cause big losses. In order find an environmentally friendly way control this pathogen, five out of sixty-nine bacterial isolates used in a screening test...
Cellobiose 2-epimerase epimerizes and isomerizes β-1,4- α-1,4-gluco-oligosaccharides. N-Acyl-d-glucosamine (DT_epimerase) from Dictyoglomus turgidum has an unusually high catalytic activity towards its substrate cellobiose. DT_epimerase was expressed, purified crystallized. Crystals were obtained of both His-tagged untagged DT_epimerase. The crystals diffracted to 2.6 Å resolution belonged the monoclinic space group P21, with unit-cell parameters a = 63.9, b 85.1, c 79.8 Å, β 110.8°. With...
Along with the co-chaperonin GroES, chaperonin GroEL plays an essential role in enhancing protein folding or refolding and protecting proteins against misfolding aggregation cellular environment. The XoGroEL gene (XOO_4288) from Xanthomonas oryzae pv. was cloned expressed, purified crystallized. crystallized using hanging-drop vapour-diffusion method a crystal diffracted to resolution of 3.4 Å. belonged orthorhombic space group P212121 14 monomers asymmetric unit, corresponding VM 2.7 Å(3)...
Cystathionine γ-synthase (CGS) catalyzes the first step in transsulfuration pathway leading to formation of cystathionine from O-succinylhomoserine and L-cysteine through a γ-replacement reaction. As an antibacterial drug target against Xanthomonas oryzae pv. (Xoo), CGS Xoo (XometB) was cloned, expressed, purified crystallized. The XometB crystal diffracted 2.4 Å resolution belonged tetragonal space group I4(1), with unit-cell parameters a=b=165.4, c=241.7 Å. There were four protomers...
