    Porphyran, which structure is similar with carrageenan and agarose, has application potential in drug form developmentas a new pharmaceutical material. Orthogonal experiment was employed to optimizethe porphyran extraction conditions from porphyra yezoensis. The extraction temperature, pH, ratio of liquid to raw material and extraction time were confirmed as 90°C, 11, and 3h Cited by: 4. Porphyra , , segundo o sistema de classificação de Hwan Su Yoon et al. (), é o nome botânico de um gênero de algas vermelhas multicelulares da família Bangiaceae.. É um género de alga vermelha foliosa composto por aproximadamente 70 espécies. [1] Cresce na zona intertidal, normalmente na área entre o intertidal superior e a zona de rebentação.

Strategies for growth management of Porphyra yezoensis (Ueda) blades in suspension cultures by Jeff T. Hafting Download PDF EPUB FB2

Porphyra yezoensis has been cultivated for centuries in Asia. Ocean-based operations, where the blade phase is grown attached to synthetic nets, and placed in the ocean for grow-out, are the norm.

There are many problems associated with this type of cultivation, many of which could potentially be overcome by using land-based tanks for grow-out of blades. However before land-based mariculture Cited by: 1. Porphyra has a heteromorphic life cycle with an alternation between a macroscopic foliose gametophytic phase and a filamentous sporophyte called the conchocelis phase (Fig.

Porphyra reproduces through both sexual and asexual modes of reproduction. In sexual reproduction, certain mature vegetative cells differentiate into carpogonia, and others on the same or different thallus.

Porphyra is a coldwater seaweed that grows in cold, shallow specifically, it belongs to red algae phylum of laver species (from which comes laverbread), comprising approximately 70 species. It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate East Asia, it is used to produce Strategies for growth management of Porphyra yezoensis book sea vegetable Class: Bangiophyceae.

The marine red macroalga Porphyra yezoensis is an important marine crop, particularly in Asian countries for the production of 'Nori'. This book presents the latest research using P. yezoensis in order to share valuable information necessary for the progress of red algal research.

The topics covered focus on developmental regulation, gene Price: $ Porphyra spp. appears on rocky shorelines throughout the world, including a few species in the tropics or at the poles. The greatest diversity is found in cold-temperate and boreal regions.

Most species appear as winter or summer annuals. Porphyra can bear desiccation, so can live in the highest, driest reaches of the intertidal zone. Porphyra thalli appear in nature as free-living organisms. A novel technique for propagation of Porphyra yezoensis Ueda blades in suspension cultures via monospores Hafting JT () Strategies for growth management of Porphyra.

The effect of tissue N and P on growth of Porphyra yezoensis (strain U) blades in suspension cultures was investigated.

Blades had the ability to store N in excess of requirements. The critical (% fresh wt) and subsistence (% fresh wt) levels of N were constant regardless of N source (NO −3 − or NH 4 +) or light level.

The marine red algal genus Porphyra, commercially known as nori, exhibits a dimorphic life cycle with a conspicuous gametophytic blade and a microscopic, filamentous, shell-boring sporophyte called the conchocelis ing to Yoshida et al.

Since several Porphyra species are extensively cultivated in Cited by:   This study centered on an innovative application of Porphyra yezoensis polysaccharide (PPS) with cationic modification as a safe and efficient nonviral gene vector to deliver a plasmid encoding human Wnt3a (pWnt3a) into human umbilical cord mesenchymal stem cells (HUMSCs).Cited by: The red seaweed Porphyra ("nori") is the basis of a US$ billion per year industry in Asia, primarily for use as human food (sushi).

There is interest in establishing a nori industry in the U.S. based on native species of Porphyra. The taxonomy and ecophysiology of native Porphyra species is not well known. The goal of this study is to examine the taxonomy and ecophysiology of Porphyra.

In order to investigate a possibility to be a culture strain of the laver Porphyra yezoensis, the physiological and morphological characters were compared between three wild strains, S1, S2 and S3, collected from the Hokkaido waters and the culture strain, UThe following seven characters were examined: growth rate, blade length/width ratio, shape of thallus, optical coloration of thallus Cited by: 1.

Porphyra yezoensis. Edible red algae (Porphyra yezoensis) are commonly consumed in South East Asia and they contain few biologically functional components, dietary fibers, taurine, polyunsaturated fatty acids, carotenoids, and porphyra amino acids as well as essential minerals, vitamins, and proteins.

Porphyra yezoensis Ueda is an intertidal marine red algae that has received increasing attention as a model organism owing to its important role in biological research and the agronomic industry. The two generations of Porphyra yezoensis, the sporophyte and the gametophyte, have the same genome but show great differences in many aspects, including structural features, habitat, and gene Cited by: 5.The objective of this research was to extract and prepare mycosporine-like amino acids (MAAs) and investigate the mechanism by which they act against UV-induced skin photoaging in Institute of Cancer Research (ICR) mice.

MAAs such as porphyra and shinorine were extracted from Porphyra yezoensis, separated, and purified using column chromatography with SA-2 cation exchange : Rui Ying, Zhaohui Zhang, Huiying Zhu, Bafang Li, Hu Hou.Currently, Algaebase [] lists and 77 species for Porphyra and Pyropia, shown in Table 1, species found mainly in northeastern Asia and suitable for aquaculture have been used as the target organisms for research studies on the food production (raw and/or processed laver) and/or substances potentially beneficial to health (e.g., porphyran, taurine, vitamins, etc.).Cited by: 1.
