Mitochondrial DNA. Part A, DNA mapping, sequencing, and analysis
We present the 61 614 bp circular-mapping mitochondrial genome of Ulva fasciata. Fifty-eight genes were identified including 29 protein-coding genes, 27 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes. Four ORFs from the Ulva sp. UNA00071828 mitogenome were conserved compared to the mitogenome of Ulva fasciata. The ∼10 000 bp size dif...

This study evaluated five experimental diets (40 % protein, 11 % lipids): the first diet (FM) was formulated with 10 % fish meal content and no fish oil; the second diet (FO) contained 0.5 % fish oil, while fish meal was totally replaced with poultry by-product meal; the third (DHA) and the fourth (LO) diets were formulated to replace fish oil with...

Annually recurrent green-tides in the Yellow Sea have been shown to result from direct disposal into the sea of fouling Ulva from Pyropia aquaculture. The role abiotic factors play in Ulva biomass accumulation on rafts was studied to find ways to mitigate this problem. Dissolved inorganic nitrogen (DIN) was very high at all sites, but the highest U...

The present study combines esophageal lavage (n = 74), stomach content (n = 52) and stable isotope analysis (n = 126) to understand the ontogenetic dietary shift of green turtles (Chelonia mydas) inhabiting the temperate waters off Uruguay. Based on esophageal and stomach analysis, green turtles in the region start consuming macroalgae soon after r...

Ulvalean algae (Chlorophyta) are most commonly described from intertidal and shallow subtidal marine environments worldwide, but are less well known from mesophotic environments. Their morphological simplicity and phenotypic plasticity make accurate species determinations difficult, even at the generic level. Here, we describe the mesophotic Ulvale...

The Yellow Sea in China has experienced annual large-scale green tides since 2007. Ulva prolifera, the dominant causative species, originating from Pyropia yezoensis aquaculture rafts, experiences periodic tidal emersion in the intertidal nursery. It was proposed that physiological adaptations of U. prolifera may enable it to survive the harsh inte...

The effects of mild-temperature thermochemical pretreatments with HCl or NaOH on the solubilization and biomethanation of Ulva biomass were assessed. Within the explored region (0-0.2M HCl/NaOH, 60-90°C), both methods were effective for solubilization (about 2-fold increase in the proportion of soluble organics), particularly under high-temperature...

A method for the stable transformation of the green marine macroalga Ulva mutabilis was developed based on vector plasmids integrating into the genome. By combination of the expression signals (promoter, enhancer, and transcriptional termination sequences) of a chromosomal rbcS gene from U. mutabilis with the bleomycin resistance gene (ble) from St...

Low-technology practices are generally the rule when cultivating marine macroalgae, and they do not necessarily comply with sustainability requirements. When integrated with other marine organisms in land-based setups, seaweed culture can be sustainable also providing environmental benefits. Major challenges of such integrated aquaculture systems, ...
