WebJan 4, 2014 · The main carotenoid in Chlorella vulgaris is lutein. The ultrasound alone or together with enzymatic pretreatment for the extraction of lutein from C. vulgaris was optimized using response surface methodology (RSM) to improve the extraction process. WebFeb 1, 1987 · A pigment accumulating in a Mendelian mutant ( y - y) of Chlamydomonas reinhardtii, which has essentially no chlorophyll and lacks inner chloroplast membranes in the light and dark, was isolated and characterized. It was identified as protoporphyrin-IX (PROTO) by spectral analysis using two different methods of extraction and fractionation.
Accumulation of protoporphyrin-IX by the chlorophyll-less
C. reinhardtii has been used as a model organism to study carotenoid synthesis and the pathways involved are well understood (Fig. 1). We previously generated single ZEP knockout mutants of CRISPR-Cas9 RNP-mediated knockout without using the hygromycin resistance gene as a selective marker in C. reinhardtii … See more We compared the growth of the wild type and zeaxanthin-accumulating mutant what we selected above (dzl) in three different light conditions (Fig. 5). Under all light conditions, the … See more To date, zeaxanthin-accumulating microorganisms have been isolated from nature or generated by random mutagenesis to overcome the limits of yield and high … See more Blocking the pathway competing with zeaxanthin biosynthesis increased the zeaxanthin pool from a given amount of carotenoids in dzl.
