Isolation of porphyran-degrading marine microorganisms from the surface of red alga, Porphyra yezoensis.
Marine microorganisms degrading porphyran (POR) were found on the surface of thalli of Porphyra yezoensis. Fifteen crude microorganism groups softened and liquefied the surface of agar-rich plate medium. Among these, 11 microorganism groups degraded porphyran that consisted of sulfated polysaccharide in Porphyra yezoensis. Following isolation, 7 POR-degradable microorganisms were isolated from ...
متن کاملEffect of dietary porphyran from the red alga, Porphyra yezoensis, on glucose metabolism in diabetic KK-Ay mice.
Porphyran (POR) from the red alga Porphyra yezoensis is a water soluble dietary fiber. In this study, we investigated the effect of dietary POR on glucose metabolism in KK-Ay mice (a model for type 2 diabetes). Mice were divided into 4 groups and fed a diet containing 5% cellulose (control), POR, POR Arg or POR K. After 3 wk of feeding, plasma insulin levels and the calculated homeostasis model...
متن کاملPreparation and antihypertensive activity of peptides from Porphyra yezoensis
This research was to develop a antihypertensive peptide, an efficient angiotensin converting enzyme (ACE) inhibitor (ACEI), from Porphyra yezoensis. Seven commercial enzymes were screened and then enzymatic hydrolysis conditions were optimised. The results showed that alcalase was the most effective for hydrolysis and its optimum conditions for achieving the highest antihypertensive activity of...
متن کاملAnti-cancer Effects of Polysaccharide and Phycocyanin from Porphyra Yezoensis
In this paper, phycocyanin and one component (PY-D2) in polysaccharide were obtained from Porphyra yezoensis to study for their potential anti-tumor effects. MTT proliferation assays showed that, at concentration of 500 mg/L for 72 h, PY-D2 treatment significantly inhibited the growth of four tumor cell lines, HO-8910, MCF-7, K562 and SMMC-7721, with the respective inhibition rates of 21.2%, 23...
متن کاملStructural features of a gene encoding the vacuolar H+-ATPase c subunit from a marine red alga, Porphyra yezoensis.
We report the nucleotide sequence of a gene encoding the c ('16 kDa') subunit of the vacuolar-type H+-ATPase (V-ATPase) from a marine red alga, Porphyra yezoensis. A cDNA clone was isolated from a leafy gametophyte cDNA library and analyzed for the sequence. The genomic DNA sequence was directly determined by nested PCR. The structural gene contained four introns within a coding sequence of 483...
