Sterols from some black sea ulvaceae

Phytochemistry, 1985
Abstract The free and esterified sterol composition of Ulva rigida and Enteromorpha linza (Ulvaceae) from the Black Sea was investigated. The main sterol component of Ulva rigida was identified as fucosterol. The influence of the season and water pollution on the sterol composition was investigated.

New Ulvaceae (Ulvophyceae, Chlorophyta) from mesophotic ecosystems across the Hawaiian Archipelago

Journal of Phycology, 2016
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.

OBSERVATIONS ON NAVICULA ULVACEA, A RARE FOLIOSE MARINE DIATOM1

Journal of Phycology, 1979
ABSTRACT Navicula ulvacea (Berkeley ex Kütz.) P. T. Cleve, a marine colonial blade‐forming diatom originally discovered in Scotland was collected at North Rustico, Prince Edward Island, during winter 1971. It formed dense stands of Porphyra‐like fronds, ranging up to 60 mm long × 20 mm wide.

SYSTEMATICS OF ULVACEAE (ULVOPHYCEAE, CHLOROPHYTA) USING NUCLEAR AND CHLOROPLAST DNA SEQUENCES

Journal of Phycology, 2000
Ulvaceae are morphologically simple, cosmopolitan green macroalgae. Family members, particularly species of Ulva and Enteromorpha, are prevalent in coastal ecosystems and responsible for “green tide” events around the world. Little is known about the evolutionary history of Ulvaceae.

Green seaweed Enteromorpha compressa ( Chlorophyta , Ulvaceae ) derived sulphated polysaccharides inhibit herpes simplex virus

International Journal of Biological Macromolecules, 2017
The herpes simplex virus (HSV) diseases represent a relevant medical and social problem due to their communicability and recurrence following latency. The green algae are rich source of polysaccharides referred to as ulvans, reported as being biologically and pharmacologically active.

Updating the Ulvaceae in the green seaweeds of Britain and Ireland

Botanica Marina
Abstract The 2007 flora “Green Seaweeds of Britain and Ireland” did not present the molecular data underpinning the Ulvaceae treatment, mostly ITS sequences. Subsequently, names have changed as type material of Ulva species is sequenced and intensive sampling with DNA barcoding adds new European species.

First report of Chloropelta caespitosa (Ulvaceae, Ulvales, Ulvophyceae) in Japan*

Phycological Research, 1996
SUMMARY Chloropelta caespitosa Tanner was found in Nagasaki Prefecture, in western Japan. This is the first record of this species in Japan and the western Pacific. Morphology and early development in culture corresponded with the original description of this species. Reproduction is by asexual quadriflagellate (rarely biflagetlate) zoospores.
