Identification of fungal species associated with chilli fruit disease in North-Central Vietnam
Chilli (Capsicum spp.), is a vegetable widely consumed all over the world. It is a crucial ingredient in many culinary dishes and a significant source of income for farmers across various countries. Unfortunately, the cultivation of this crop is not without its challenges, as it can be affected by pathogenic fungi, which can lead to a decrease in yield and quality.…

Isolation of an agricultural soil agarolytic Flavobacterium sp. AT2 and its agarase characterization
This study aimed to isolate a novel agarase-producing soil bacterium and characterize its agarose, which is known to produce biofunctional agarooligosaccharides or neo-agarooligosaccharides. A novel agar-degrading bacterium, namely AT2, was isolated from the agricultural soil and the enzyme activity was identified on a specific medium. The 16S rRNA nucleotide sequence represented 99% identity with that of the members of the…

Potential of Biosynthesized Silver Nanoparticles (AgNPs) to Promote Growth and Control Plant Pathogenic Bacteria of Lotus (Nelumbo nucifera)
Nanotechnology has recently emerged as a rapidly growing area in science, medicine, disinfection, and agriculture. Bacteria pathogens affect lotus agriculture both in crop yield and economic loss. This study aimed to identify pathogen that caused brown leaf spot disease on the lotus and evaluate the antimicrobial efficacy in vitro of silver nanoparticles. Molecular based identification using 16S ribosomal DNA sequences revealed that…

Isolation of bacteria displaying potent antagonistic activity against fungi causes anthracnose disease in chili
Anthracnose is a common disease on many crops caused by Colletotrichum species, and it leaves serious consequences, especially on chili. Beta-1,3 glucanase is a semi-constitutive hydrolytic enzyme that is involved in the biological regulation of plant pathogens. Its main function is the breakdown of beta-1,3-glucan, a major constituent of the fungal cell wall. In a study conducted in Vietnam’s Quang Tri and Thua…
