| antifouling potential of some marine organisms from india against species of bacillus and pseudomonas. | crude methanolic extracts of 37 marine organisms (16 species of flora, 21 species of fauna) were screened for antibacterial properties against 5 strains of bacteria isolated from marine environments. of these, 10 plant and 9 animal extracts exhibited antibacterial activity against at least one bacterial strain. the extracts of 6 species were active against all the strains: i.e., stoechospermum marginatum (brown algae), cymodocea rotundata (seagrass), petrosia sp. and psammaplysilla purpurea (spo ... | 2002 | 14961269 |
| dugong grazing and turtle cropping: grazing optimization in tropical seagrass systems? | grazing by dugongs and cropping by green turtles have the capacity to alter the subsequent nutritional quality of seagrass regrowth. we examined the effects of simulated light and intensive grazing by dugongs and cropping by turtles on eight nutritionally relevant measures of seagrass chemical composition over two regrowth periods (short-term, 1-4 months; long-term, 11-13 months) at two seagrass communities (a mixed species community with zostera capricorni, halophila ovalis, halodule uninervis, ... | 2006 | 16821013 |
| cultivation-dependent analysis of the microbial diversity associated with the seagrass meadows in xincun bay, south china sea. | microbial communities have largely existed in the seagrass meadows. a total of 496 strains of the bacteria in the seagrass meadows, which belonged to 50 genera, were obtained by the plate cultivation method from three sites of xincun bay, south china sea. the results showed that bacillales and vibrionales accounted for the highest proportions of organisms in all communities. the diversity of the bacteria in the sediment was higher than that associated with seagrass. thalassia hemperichii possess ... | 2015 | 26197731 |
| rapid discrimination between four seagrass species using hybrid analysis. | biological species are traditionally identified based on their morphological features and the correct identification of species is critical in biological studies. however, some plant types, such as seagrass, are taxonomically problematic and difficult to identify. furthermore, closely related seagrass species, such as halophila spp, form a taxonomically unresolved complex. although some seagrass taxa are easy to recognize, most species are difficult to identify without skilled taxonomic or molec ... | 2015 | 25966167 |
| epiphytic cyanobacteria of the seagrass cymodocea rotundata: diversity, diel nifh expression and nitrogenase activity. | seagrasses are photoautotrophic, ecologically important components of many globally widespread coastal ecosystems, in which combined nitrogen may limit their production. we examined the biodiversity and diazotrophic capacity of microbial epiphytes associated with the phyllosphere of the seagrass cymodocea rotundata of the western indian ocean. light microscopy, 16s rrna and nifh gene analysis revealed the dominance of cyanobacteria in the epiphytic microbial community. most phylotypes were relat ... | 2013 | 23754717 |
| in vitro antibacterial, cytotoxicity and haemolytic activities and phytochemical analysis of seagrasses from the gulf of mannar, south india. | it is essential to study the phytochemical constituents and toxicological properties of seagrasses when considering their food applications. aqueous methanolic extracts of six seagrasses were evaluated for their antibacterial, cytotoxic (brine shrimp leathality assay) and haemolytic activity. thin layer chromatography (tlc) and phytochemical analysis were used to compare the phytochemical profiles of six seagrasses. among the six seagrasses examined, halodule pinifolia and cymodocea rotundata sh ... | 2013 | 23194552 |
| chemical composition and antibacterial activity of indian seagrasses against urinary tract pathogens. | seagrasses have a long history of being used for a variety of remedial purposes, such as the fever, skin diseases, muscle pains, wounds and stomach problems. hence it is essential to study their bioactive metabolites and medicinal properties when considering their food applications. the chemical composition of six seagrasses were determined and evaluated for their potential to urinary tract infection bacteria (uti). the chemical composition determined by gc-ms yielded 24 compounds. for the first ... | 2012 | 22980830 |
| chemometric studies of multielemental composition of few seagrasses from gulf of mannar, india. | this paper discusses the determination of minerals content (cadmium, cobalt, chromium, copper, nickel, lead, manganese, magnesium, iron, zinc, sodium, potassium and calcium) of six seagrass samples, enhalus acoroides, thalassia hemprichii, halodule pinifolia, syringodium isoetifolium, cymodocea serrulata and cymodocea rotundata using inductively coupled plasma optical emission spectrophotometry and flame photometer. principal component analysis (pca) and hierarchical cluster analysis revealed di ... | 2011 | 21128004 |
| temporal changes in the abundance, leaf growth and photosynthesis of three co-occurring philippine seagrasses. | the analysis of the temporal changes in shoot density, areal leaf biomass, leaf growth and parameters of the photosynthesis-irradiance relationship of three tropical seagrass species (enhalus acoroides, thalassia hemprichii and cymodocea rotundata), co-existing in a shallow subtidal meadow in cape bolinao, philippines, shows that species-specific traits are significant sources of temporal variability, and indicates that these seagrass species respond differently to a common environmental forcing ... | 2001 | 11358580 |
