Chemical compositions of the marine algae Gracilaria salicornia (Rhodophyta) and Ulva lactuca (Chlorophyta) as a potential food source.

Background: The nutritional compositions of two edible red (Gracilaria salicornia) and green (Ulva lactuca) seaweeds were determined to evaluate their possible uses as potential food ingredients.

Results: In general, these species contained limited amounts of lipids ranging between 0.99 and 2.

Cytoplasmic reorganization accompanies the deposition of a bipolar cell wall in the large-celled red alga Anotrichium tenue.

Protoplast isolation and regeneration in the marine red alga Porphyra nereocystis.

We have developed a method for isolating viable protoplasts from the blade phase of the epiphytic marine red alga Porphyra nereocystis Anderson, using a two-step enzymatic digestion with commercially available enzymes. The first step uses papain, the second step uses abalone acetone powder. The method is rapid and gives a high yield of viable protoplasts.

Porphyra nereocystis: A dual-daylength seaweed.

Conchospores from the perennial conchocelis phase of the annual, epiphytic, marine red alga Porphyra nereocystis Anderson, which in nature lives on the large annual kelp Nereocystis luetkeana (Mertens) Postels et Ruprecht, are released in culture only in response to a short-day photoperiod treatment followed by a long-day treatment. Each treatment requires a minimum of three to four weeks and is enhanced by lower temperature during the second photoperiod treatment. To our knowledge P.
