Glycosylation of bisphenol A, which is an endocrine disrupting chemical, was investigated using immobilized marine microalga and plant cells from the viewpoint of bioremediation of bisphenol A. Immobilized marine microalga of Amphidinium crassum glucosylated bisphenol A to the corresponding glucoside. On the other hand, bisphenol A was glycosylated to its glucoside, diglycoside, gentiobioside, ...

In the presence of PP, as an energy source, the tonoplast-bound inorganic pyrophosphatase from Catharanthus roseus cells is able to create a proton-gradient which can drive the synthesis of ATP from ADP and Pi. ATP synthesis is linked to the pH-gradient dissipation as monitored by the recovery of the fluorescence intensity of quinacrine and by the amount of synthesized ATP measured by the biolu...

The (seco)iridoids and their derivatives, the monoterpenoid indole alkaloids (MIAs), form two large families of plant-derived bioactive compounds with a wide spectrum of high-value pharmacological and insect-repellent activities. Vinblastine and vincristine, MIAs used as anticancer drugs, are produced by Catharanthus roseus in extremely low levels, leading to high market prices and poor availab...

Endophytic microbia are known as natural sources for producing valuable enzymes. In this study, four endophytic fungi were isolated from roots of local Catharanthus roseus (L.) G. Don var. (purple flower) and C. ocellatus (red stamens white widely grown in Nha Trang. They identified Fusarium solani RN1, Chaetomium funicola RN3, Penicillium rugulosum RN4 homopilatum WN1 based on morphologies col...

Endophytic fungi isolated from Catharanthus roseus were screened for the production of vincristine and vinblastine. Twenty-two endophytic fungi isolated from various tissues of C. roseus were characterized taxonomically by sequence analysis of the internal transcribed spacer (ITS) region of rDNA and grouped into 10 genera: Alternaria, Aspergillus, Chaetomium, Colletotrichum, Dothideomycetes, Eu...

Catharanthus roseus is an important medicinal plant, which produces a variety of indole alkaloids of significant pharmaceutical relevance. In the present study, we aimed to investigate the potential stress-induced increase of indole alkaloid biosynthesis in C. roseus using proteomic technique. The contents of the detectable alkaloids ajmalicine, vindoline, catharanthine, and strictosidine in C....
