Harmful algal blooms have caused enormous damage to the marine ecosystem and the coastal economy in China. In this paper, a bacterial strain B1, which had strong algicidal activity against Phaeocystis globosa, was isolated from the coastal waters of Zhuhai in China. The strain B1 was identified as Bacillus sp. on the basis of 16S rDNA gene sequence and morphological characteristics. To evaluate...

Co-culturing and using cell-free filtrates are common methods for investigating allelopathy of marine phytoplankton; however, these often yield inconsistent or even contradictory results. The induced release allelopathic compounds has been hypothesized as a mechanism to explain the discrepancy. Here, we used experiments assess inducibility by diatom, Thalassiosira weissflogii, on colony formati...

Malassezia globosa cytochromes P450 CYP51 and CYP5218 are sterol 14α-demethylase (the target of azole antifungals) and a putative fatty acid metabolism protein (and a potential azole drug target), respectively. Lanosterol, eburicol and obtusifoliol bound to CYP51 with Kd values of 32, 23 and 28 μM, respectively, catalyzing sterol 14α-demethylation with respective turnover numbers of 1.7 min(-1)...

Evolutionary relationships within the poorly known and anomalous South African endemic genus Lichtensteinia were elucidated. Phylogenetic analysis of morphological and anatomical characters suggests that there are two main groups of species, viz. the L. obscura–L. globosa–L. interrupta (including L. kolbeana) clade and the L. latifolia–L. trifida–L. lacera–L. crassijuga clade. Furthermore, Lich...

ETHNOPHARMACOLOGICAL RELEVANCE Leaf extracts of Buddleja globosa (Buddlejaceae) are used in Chilean folk medicine for wound healing. The anti-inflammatory (topic and per os), analgesic (per os) effects and the antioxidant activity of Buddleja globosa were for the first time reported by us. AIM OF THE STUDY Assess the antinociceptive activity of the methanol sequential and global extracts usin...

the aim of this study was to assess skin colonization by malassezia species in full-term healthy newborn calves and their dams. two hundred samples from the skins and ears of 50 neonatal calves and their dams were examined on two occasions, first and fourth weeks after birth. all of the samples were determined by cytological examination and fungal culture. the isolated yeasts were identified fo...

background and objectives: the genus malassezia contains an expanding list of lipophilic yeasts involve in the etiology of various superficial fungal infections. pityriasis versicolor (pv) is the most prevalent malassezia -related infection distributed worldwide. in the present study, clinical and epidemiological features of the genus malassezia are discussed with special focus on pv in iran. m...

The enhancement of plant secondary metabolite production in cell suspension cultures through biotic or abiotic elicitation has become a potential biotechnological approach for commercialization or large-scale production of bioactive compounds. Gymnema sylvestre R.Br. is an important medicinal plant, rich in a group of oleanane triterpenoid saponins called gymnemic acid, well known for its anti-...

Lipophilic yeast of the genus Malassezia (Pityrosporum) belongs to the normal flora of human skin and many warm-blooded animals. These fungi can produce a diverse range of diseases that the best known and most frequent of them is pityriasis versicolor, a chronic recurrent skin disease occurring primarily in tropical regions. The genus Malassezia has been recently enlarged to include seven disti...
