The domestic wastewater treatment capacity of Spirulina platensis SP4 and the application of the treated wastewater in stimulating rice germination
Vietnam Journal of Biotechnology - Tập 20 Số 4 - Trang 773-784 - 2022
Many scientists are interested in microalgae and cyanobacteria because of their richness in high-value bioactive metabolites (proteins, lipids, vitamins, plant growth regulators, and others). Microalgae and cyanobacteria can be used to produce valuable commodities such as dietary supplements, biofuel, animal feed, and agricultural fertilizer, etc. To improve the economic feasibility of the cyanoba......
In vitro safety evaluation of Bacillus subtilis species complex isolated from Vietnam and their additional beneficial properties
Vietnam Journal of Biotechnology - Tập 20 Số 4 - Trang 727-740 - 2022
Bacillus genus are Gram-positive, rod shaped, spore-forming, aerobic or facultative anaerobic bacteria, which have the ability to produce a wide variety of enzymes, antimicrobial compounds, vitamins, and carotenoids. Nowadays, Bacillus species have been increasingly proposed for use as probiotics or feed additives as B. amyloliquefaciens, B. licheniformis, B. subtilis, and B. pumilus because of th......
A study on genetic diversity of bagrid catfish (Hemibagrus guttatus Lacepede, 1803) using microsatellite markers
Vietnam Journal of Biotechnology - Tập 16 Số 1 - Trang 59-65 - 2018
Bagrid catfish (Hemibagrus guttatus Lacepede, 1803) is a wild species of high economic value in Northern Vietnam. Artificial reproduction of bagrid catfish requires sources of quality fingerlings in terms of genetics. In fact, bagrid catfish is endangered due to overhunting. Until now, studying on bagrid catfish was mainly focused on biology characterictics and artificial breeding. In this study, ......

Investigating the diversity of arbuscular mycorrhizal fungi from Gymnema sylvestre and Curcuma longa in Vietnam
Vietnam Journal of Biotechnology - - 2018
Arbuscular mycorrhizal (AM) fungi are soil eukaryotes that belong to phylum Glomeromycota and have symbiosis with the vast majority of higher plants’ roots. AM fungi are believed to be coevolved with terrestrial plants, the abundance and diversity of AM fungal communities as a result are host plant dependent. A survey of AM fungi from the rhizospheres of medicinal plants in Northern Vietnam includ......

Expression of genes involved in immune regulation in chronic myeloid leukemia
Vietnam Journal of Biotechnology - Tập 19 Số 1 - Trang 51-60 - 2021
Chronic myeloid leukemia (CML) is a blood cancer involved in abnormal proliferation of myeloid cells at all stages of differentiation. Translocation of regions of the BCR and ABL genes, leading to the fusion gene BCR-ABL, which forms the Philadelphia (Ph) chromosome, is the cause of more than 90% of CML. The BCR-ABL protein shows abnormal tyrosine kinase activity, leading to changes in proliferati......

Effect of calcium hypochlorite on surface sterilization and seedling growth of Vietnamese coconut varieties
Vietnam Journal of Biotechnology - - 2022
Coconut (Cocos nucifera L.) or 'the tree of life' is one of the most important palm crops due to its versatility. Reduction in coconut productivity due to natural calamity and disease threats has raised the urgent need to develop in vitro techniques that can overcome the obstacles of the traditional breeding method. Embryo culture is one of the earliest in vitro culture techniques applied to pract......
Optimization of biosurfactant production for enhanced crude-oil degradation by a Candida tropicalis 1214-BK14 isolated from white tiger oilfiel - Vung Tau, Vietnam
Vietnam Journal of Biotechnology - Tập 15 Số 1 - Trang 189-196 - 2017
Biosurfactants are amphiphilic molecules with effective surface-active and biological properties applicable to replace synthetic surfactant in petroleum industry. Interest in microbial surfactants has been steadily increasing in recent years, as they have numerous advantages compared to chemical surfactants including a lower toxicity, better environmental compatibility and effective properties at ......

Effects of simulated microgravity on seed germination, growth, development and accumulated secondary compounds of Hibiscus sagittifolius Kurz. cultured in vitro
Vietnam Journal of Biotechnology - Tập 15 Số 1 - Trang 73-85 - 2017
In the present study, Hibiscus sagittifolius Kurz. seeds were used as the plant materials for studying on the effects of simulated microgravity (on a 2D clinostat) on seed germination, shoot multiplication, growth, development and secondary metabolite accumulation. After surface sterilization, seeds were cultured on MS medium supplemeted with 30 g/l sucrose and 9 g/l agar in Petri dishes (9 seeds ......

ISOLATION AND SELECTION OF INDIGENOUS ANTIFUNGAL MICROORGANISMS AGAINST PATHOGENIC FUNGI OF PEPPER PLANT IN TAY NGUYEN
Vietnam Journal of Biotechnology - Tập 16 Số 2 - Trang 385-392 - 2018
The pathogenic fungi often cause huge impacts on agricultural crops, and occupy over 80% of plant diseases. Fusarium oxysporum and Rhizoctonia solani are fungal pathogens that can lead to rapid development of plant diseases on important crops in Tay Nguyen (e.g., pepper, coffee, rubber, cashew). Therefore, the study of microorganisms with bioactivity against these pathogens is essential to control......

α-amylase and α-glucosidase inhibiting effects of Canna edulis Ker Gawl rhizome
Vietnam Journal of Biotechnology - Tập 21 Số 3 - Trang 505-512 - 2023
Screening inhibitors of α-amylase and α-glucosidase from medicinal plants is a topic of interest in the world. Canna edulis Ker Gawl is an important rhizome plant belonging to the genus Canna of the family Cannaceae. It is traditionally used to treat many conditions such as gonorrhea, pain, bruises, diarrhea, hepatitis, chest pain and heart diseases. The potential of this plant in the treatment an......
