| diglucosyl-glycerolipids from the marine sponge-associated bacillus pumilus strain aas3: their production, enzymatic modification and properties. | the marine strain bacillus pumilus strain aas3, isolated from the mediterranean sponge acanthella acuta, produced a diglucosyl-glycerolipid, 1,2-o-diacyl-3-[beta-glucopyranosyl-(1-6)-beta-glucopyranosyl)]glycerol, with 14-methylhexadecanoic acid and 12-methyltetradecanoic acid as the main fatty acid moieties (ggl11). on a 30 l scale, using artificial seawater supplemented with glucose (20 g/l), yeast extract (10 g/l), and suitable nitrogen/phosphate sources, growth-associated glycoglycerolipid p ... | 2004 | 14593508 |
| comparative bioaccumulation kinetics of trace elements in mediterranean marine sponges. | while marine organisms such as bivalves, seagrasses and macroalgae are commonly used as biomonitors for the environment pollution assessment, widely distributed sponges received little attention as potential helpful species for monitoring programmes. in this study, the trace element and radionuclide bioaccumulation and retention capacities of some marine sponges were estimated in a species-comparative study using radiotracers technique. six mediterranean species were exposed to background dissol ... | 2012 | 22633418 |
| comparative studies on two potential methods for the biotechnological production of sponge biomass. | the production of marine sponge biomass is one of the main outstanding goals of marine biotechnology. due to the increased number of sponge secondary metabolites of economical value the interest in sponge cultivation increased over the last years, too. therefore, we examined cultivation properties of 11 mediterranean sponge species. two methodologies were tested: functional fragment culture and multicell reaggregate culture. the in vitro cultivation of sponge fragments without further dissociati ... | 2001 | 11640986 |
