Quantitative structure-activity relationship models were obtained by applying the Molecular Descriptor Family approach to eight ordnance compounds with different toxicity on five marine species (arbacia punctulata, dinophilus gyrociliatus, sciaenops ocellatus, opossum shrimp, and ulva fasciata). The selection of the best among molecular descriptors generated and calculated from the ordnance com...

A growing interest in the development of oceanic coastal shores has arisen over past decade, seeking alternative sustainable food sources and other valuable products. Our initiative aims at exploiting potential marine seaweeds Europe. Building on successes previous EU pan-European projects seaweeds, due unique characteristics genus Ulva (Linnaeus, 1753), we have identified these green algae as ...

Seaweed is a promising sustainable source of vegan protein as its farming does not require arable land, pesticides/insecticides, nor freshwater supply. However, to be explored novel the content and nutritional quality in seaweed need improved. We assessed influence pH-shift processing on degree hydrolysis (%DH), protein/peptide size distribution, accessibility, cell bioavailability Ulva fenestr...

Present study consists the, effect of temperature (10-30C), salinity (15-35 psu) and biofilm on the settlement of Enteromorpha flexousa zoospores. Settlement of zoospores was significantly (p<0.05) influenced by both temperature and salinity. Highest percentage of settlement occurred at 25C and 30 psu respectively. Subsequently the influence of biofilm was evaluated at the optimum 25C and 30 ps...

We established a two-step production process using immobilized S. cerevisiae and P. stipitis yeast to produce ethanol from seaweed (U. pertusa Kjellman) hydrolysate. The process was designed to completely consume both glucose and xylose. In particular, the yeasts were immobilized using DEAE-corncob and DEAE-cotton, respectively. The first step of the process included a continuous column reactor...

The influence of ambient water quality on the settlement of barnacles and the green alga Enteromorpha spp. to an artificial substratum in the estuaries of Sydney, Australia, was investigated to test the efficacy of both groups of organisms as indicators of changes in water quality due to urban stormwater runoff and/or sewage overflows. Wooden settlement panels were immersed for 4 months on 17 o...

Analysis of the natural abundance C content of dibutyl phthalate (DBP) from two edible brown algae, Undaria pinnatifida and Laminaria japonica, and a green alga, Ulva sp., revealed that the DBP was naturally produced. The natural abundance C content of di-(2-ethylhexyl) phthalate (DEHP) obtained from the same algae was about 50-80% of the standard sample and the C content of the petrochemical (...

The knowledge of marine algae species composition is imperative not only for understanding the structure, function and biogeographical affinities but also planning strategies conservation management. This study was carried out to determine diverse evaluate some use-values green macroalgae from genus Ulva in Hai Phong, where many different habitats such as estuarine floodplains, lagoons or small...
