Exploring the Phytochemicals of Acacia melanoxylon R. Br.

ABSTRACT: Invasive species are currently a world menace to the environment, although the study of their chemistry may provide a means for their future beneficial use. From a study of Portuguese Acacia melanoxylon R. Br. five known compounds were isolated: lupeol, 3β-Z-coumaroyl lupeol, 3β-E-coumaroyl lupeol (dioslupecin A), kolavic acid 15-methyl ester and vomifoliol (blumenol A). Their structures were elucidated by 1D and 2D NMR spectroscopy and mass spectrometry, and as a result some corrections are made to their previous 13C NMR assignments. Cytotoxicity of 3β-E-coumaroyl lupeol (dioslupecin A) and kolavic acid 15-methyl ester was evaluated against HCT116 human colorectal cancer cells although biological activity was not evident.

Mesorhizobium acaciae sp. nov., isolated from root nodules of Acacia melanoxylon R. Br.

Project description:Three novel strains, RITF741T, RITF1220 and RITF909, isolated from root nodules of Acacia melanoxylon in Guangdong Province of China, have been previously identified as members of the genus Mesorhizobium, displaying the same 16S rRNA gene RFLP pattern. Phylogenetic analysis of 16S rRNA gene sequences indicated that the three strains belong to the genus Mesorhizobium and had highest similarity (100.0 %) to Mesorhizobium plurifarium LMG 11892T. Phylogenetic analyses of housekeeping genes recA, atpD and glnII revealed that these strains represented a distinct evolutionary lineage within the genus Mesorhizobium. Strain RITF741T showed >73 % DNA–DNA relatedness with strains RITF1220 and RITF909, but < 60 % DNA–DNA relatedness with the closest type strains of recognized species of the genus Mesorhizobium. They differed from each other and from their closest phylogenetic neighbours by presence/absence of several fatty acids, or by large differences in the relative amounts of particular fatty acids. While showing distinctive features, they were generally able to utilize a wide range of substrates as sole carbon sources based on API 50CH and API 20NE tests. The three strains were able to form nodules with the original host Acacia melanoxylon and other woody legumes such as Acacia aneura, Albizia falcataria and Leucaena leucocephala. In conclusion, these strains represent a novel species belonging to the genus Mesorhizobium based on the data obtained in the present and previous studies, for which the name Mesorhizobium acaciae sp. nov. is proposed. The type strain is RITF741T ( = CCBAU 101090T = JCM 30534T), the DNA G+C content of which is 64.1 mol% (T m).

Bradyrhizobium ganzhouense sp. nov., an effective symbiotic bacterium isolated from Acacia melanoxylon R. Br. nodules.

Project description:Three slow-growing rhizobial strains, designated RITF806(T), RITF807 and RITF211, isolated from root nodules of Acacia melanoxylon grown in Ganzhou city, Jiangxi Province, China, had been previously defined, based on amplified 16S rRNA gene restriction analysis, as a novel group within the genus Bradyrhizobium. To clarify their taxonomic position, these strains were further analysed and compared with reference strains of related bacteria using a polyphasic approach. According to 16S rRNA gene sequence analysis, the isolates formed a group that was closely related to 'Bradyrhizobium rifense' CTAW71, with a similarity value of 99.9%. In phylogenetic analyses of the housekeeping and symbiotic gene sequences, the three strains formed a distinct lineage within the genus Bradyrhizobium, which was consistent with the results of DNA-DNA hybridization. In analyses of cellular fatty acids and phenotypic features, some differences were found between the novel group and related species of the genus Bradyrhizobium, indicating that these three strains constituted a novel group distinct from any recognized species of the genus Bradyrhizobium. Based on the data obtained in this study, we conclude that our strains represent a novel species of the genus Bradyrhizobium, for which the name Bradyrhizobium ganzhouense sp. nov. is proposed, with RITF806(T) ( = CCBAU 101088(T) = JCM 19881(T)) as the type strain. The DNA G+C content of strain RITF806(T) is 64.6 mol% (T(m)).

Bioactive Phytochemicals of Acacia saligna.

Project description:Acacia saligna is native to Western Australia. It has become an introduced and fast-growing plant in other parts of the world due to its ability to adapt to drought, saline and alkaline soils, and hast growing environments. Studies on the bioactivities and phytochemicals of the plant extracts were conducted. However, comprehensive information that links those bioactivities to the identified compounds in the plant's extracts is still lacking. Data gathered in this review revealed a rich chemical diversity of hydroxybenzoic acids, cinnamic acids, flavonoids, saponins, and pinitols in A. saligna growing in Egypt, Saudi Arabia, Tunisia, South Africa, and Australia. The variability in phytochemical composition and quantity could be attributed to plant parts, growing locations, extraction solvents, and analysis methods. Identified phytochemicals support observed biological activities such as antioxidant, antimicrobial, anticancer, α-glucosidase inhibition, and anti-inflammation in the extracts. The knowledge of chemical structures, biological activities, and possible mechanisms of action of the bioactive phytochemicals identified in A. saligna were discussed. In addition, the structure-activity relationships of dominant active compounds were examined to explain the bioactivities exerted by A. saligna extracts. The review provides valuable insights towards future research and the development of new therapeutics from this plant.

Genotype-Environment Interaction and Horizontal and Vertical Distributions of Heartwood for Acacia melanoxylon R.Br.

Project description:Acacia melanoxylon (blackwood) is a valuable wood with excellent-quality heartwood extensively utilized worldwide. The main aim of this study was to confirm the horizontal and vertical variation and provide estimated values of genetic gains and clonal repeatabilities for improving breeding program of A. melanoxylon. Six blackwood clones at 10 years old were analyzed in Heyuan and Baise cities in China. Stem trunk analysis was conducted for sample trees to explore the differences between heartwood and sapwood. The heartwood radius (HR), heartwood area (HA), and heartwood volume (HV) in heartwood properties decreased as tree height (H) in growth traits increased, and the HV = 1.2502 DBH (diameter at breast height)1.7009 model can accurately estimate the heartwood volume. Furthermore, G × E analysis showed that the heritabilities of the eleven indices, including DBH, DGH (diameter at ground height), H, HR, SW (sapwood width), BT (bark thickness), HA, SA (sapwood area), HV, HRP (heartwood radius percentage), HAP (heartwood area percentage), and HVP (heartwood volume percentage) were between 0.94 and 0.99, and repeatabilities of the eleven indices were between 0.74 and 0.91. Clonal repeatability of DBH (0.91), DGH (0.88), and H (0.90) in growth traits, HR (0.90), HVP (0.90), and HV (0.88) in heartwood properties were slightly higher than for SA (0.74), SW (0.75), HAP (0.75), HRP (0.75), and HVP (0.75). These data also implied that the growth characteristics of heartwood and sapwood of blackwood clones were less affected by the environment and had substantial heritability.

Fibre Morphological Characteristics of Kraft Pulps of Acacia melanoxylon Estimated by NIR-PLS-R Models.

Project description:In this paper, the morphological properties of fiber length (weighted in length) and of fiber width of unbleached Kraft pulp of Acacia melanoxylon were determined using TECHPAP Morfi® equipment (Techpap SAS, Grenoble, France), and were used in the calibration development of Near Infrared (NIR) partial least squares regression (PLS-R) models based on the spectral data obtained for the wood. It is the first time that fiber length and width of pulp were predicted with NIR spectral data of the initial woodmeal, with high accuracy and precision, and with ratios of performance to deviation (RPD) fulfilling the requirements for screening in breeding programs. The selected models for fiber length and fiber width used the second derivative and first derivative + multiplicative scatter correction (2ndDer and 1stDer + MSC) pre-processed spectra, respectively, in the wavenumber ranges from 7506 to 5440 cm-1. The statistical parameters of cross-validation (RMSECV (root mean square error of cross-validation) of 0.009 mm and 0.39 μm) and validation (RMSEP (root mean square error of prediction) of 0.007 mm and 0.36 μm) with RPDTS (ratios of performance to deviation of test set) values of 3.9 and 3.3, respectively, confirmed that the models are robust and well qualified for prediction. This modeling approach shows a high potential to be used for tree breeding and improvement programs, providing a rapid screening for desired fiber morphological properties of pulp prediction.

Valorisation Potential of Invasive Acacia dealbata, A. longifolia and A. melanoxylon from Land Clearings.

Project description:Acacia spp. are invasive in Southern Europe, and their high propagation rates produce excessive biomass, exacerbating wildfire risk. However, lignocellulosic biomass from Acacia spp. may be utilised for diverse biorefinery applications. In this study, attenuated total reflectance Fourier transform infrared spectroscopy (FTIR-ATR), high-performance anion-exchange chromatography pulsed amperometric detection (HPAEC-PAD) and lignin content determinations were used for a comparative compositional characterisation of A. dealbata, A. longifolia and A. melanoxylon. Additionally, biomass was treated with three white-rot fungi species (Ganoderma lucidum, Pleurotus ostreatus and Trametes versicolor), which preferentially degrade lignin. Our results showed that the pre-treatments do not significantly alter neutral sugar composition while reducing lignin content. Sugar release from enzymatic saccharification was enhanced, in some cases possibly due to a synergy between white-rot fungi and mild alkali pretreatments. For example, in A. dealbata stems treated with alkali and P. ostreatus, saccharification yield was 702.3 nmol mg-1, which is higher than the samples treated only with alkali (608.1 nmol mg-1), and 2.9-fold higher than the non-pretreated controls (243.9 nmol mg-1). By characterising biomass and pretreatments, generated data creates value for unused biomass resources, contributing to the implementation of sustainable biorefining systems. In due course, the generated value will lead to economic incentives for landowners to cut back invasive Acacia spp. more frequently, thus reducing excess biomass, which exacerbates wildfire risk.
