“…Both PE and PC, fluorescent proteins in the auxiliary photosynthetic complexes of red macroalgae, can also capture light energy (Dagnino-Leone et al, 2022). Chl a, carotenoid, PE, and PC are the primary photosynthetic pigments of red macroalgae and are critical targets for metals.…”

Mechanism of macroalgae Gracilaria bailiniae responding to cadmium and lanthanum

et al. 2022

Macroalgae can accumulate a wide array of metals, leading to their appliance as biomonitors of aquatic environments. With the rapid development of industrial and agricultural-based activities, Cd pollution in aquatic environments is considered an increasingly severe problem worldwide. Although La could alleviate the Cd stress in higher terrestrial plants, the response mechanisms of macroalgae to Cd and La are unknown. Along these lines, in this work, Cd significantly affected the growth, internal cellular structure, photosynthesis, pigment content, antioxidant enzyme activity, and lipid peroxidation level of G. bailiniae. However, the presence of La alleviated these adverse effects from Cd. Furthermore, the response mechanism of G. bailiniae to Cd was attributed to the self-antioxidant ability enhancement, membrane defense, and programmed-cellular regulation. However, the presence of La mediated the biosynthesis of both flavonoids and lipids, which inhibited the Cd accumulation, modulated algal stress signalling networks, renewed the impaired chlorophyll molecule, maintained the activity of the crucial enzyme, enhanced antioxidant ability, and maintained the stabilization of redox homeostasis, alleviating the adverse impact from Cd and improve the growth of G. bailiniae. The experimental results successfully demonstrate a new detoxicant to alleviate Cd stress, promoting a more comprehensive array of macroalgal applications.

“…PE from freshwater and soil cyanobacteria carry PEB chromophores solely, with absorption and fluorescence emission spectra resembling the spectral properties of C-PE-I [ 31 ]. C-PE-I carried five PEBs (αβ) that were covalently bonded to the cysteine (Cys) residue (α-84, α-140 or β-143, β-84 or β-82, β-50 or β-61, and β-155 or β-159) [ 21 ]. C-PE-I is a disk-shaped hexamer formed by two trimeric (αβ) 3 through face-to-face aggregation.…”

“…In recent years, previous reviews have reported on the scientific progress and challenges of microalgal pigments [ 17 , 18 , 19 ]. Instead of a detailed report on C-PE, the existing publications focused on the general characteristics and features of cyanobacterial PBP, particularly C-PC, while overlooking the specific strains, characteristics, and upstream and downstream processes specifically optimized for C-PE as well as the specific applications of C-PE [ 20 , 21 ]. Spirulina platensis is the most commonly used strain since it has been recognized as an effective multiple-product-producing strain for decades [ 20 ].…”

A Review on a Hidden Gem: Phycoerythrin from Blue-Green Algae

et al. 2022

Phycoerythrin (PE) is a pink/red-colored pigment found in rhodophytes, cryptophytes, and blue-green algae (cyanobacteria). The interest in PE is emerging from its role in delivering health benefits. Unfortunately, the current cyanobacterial-PE (C-PE) knowledge is still in the infant stage. It is essential to acquire a more comprehensive understanding of C-PE. This study aimed to review the C-PE structure, up and downstream processes of C-PE, application of C-PE, and strategies to enhance its stability and market value. In addition, this study also presented a strengths, weaknesses, opportunities, and threats (SWOT) analysis on C-PE. Cyanobacteria appeared to be the more promising PE producers compared to rhodophytes, cryptophytes, and macroalgae. Green/blue light is preferred to accumulate higher PE content in cyanobacteria. Currently, the prominent C-PE extraction method is repeated freezing–thawing. A combination of precipitation and chromatography approaches is proposed to obtain greater purity of C-PE. C-PE has been widely exploited in various fields, such as nutraceuticals, pharmaceuticals, therapeutics, cosmetics, biotechnology, food, and feed, owing to its bioactivities and fluorescent properties. This review provides insight into the state-of-art nature of C-PE and advances a step further in commercializing this prospective pigment.

“…PCY has been observed as an inhibitor of viral protease activities (i. e. SARS-CoV-2) [133,134], which could mean antiviral protection. The anti-diabetes activity of phycocyanobilin could be due to the inhibition of NADPH oxidase and the protective effects against human lymphatic endothelial cells apoptosis, which also explains its neuroprotective effects [135].…”

Progress in Microalgae Research - A Path for Shaping Sustainable Futures

Cryptophytes are single-cell biflagellate algae, with extrusive organelles called ejectosomes. They live in fresh and marine water, mainly in shaded environments where light levels are reduced relative to the surface. They are the product of a secondary endosymbiosis of a red alga, which still retains the endosymbiont nucleus’s reminiscences and has four membranes around its plastids. Cryptophytes have a metabolic diversity that makes them very interesting from a nutritional point of view since they present a balance of fatty acids w3/w6, sterols, carotenoid pigments, and phycobiliproteins, these last also have antioxidant effects. Their composition makes them attractive for food in aquaculture and human consumption, pharmaceuticals and cosmetics; their fluorescent potential has attracted the attention of researchers in genomics, neuroscience and molecular biology. The biochemical composition of the cells is modulated by illumination, available nutrients, and its growth phase. This work reviews the general biology of cryptophytes, emphasizing the photosynthetic ones, culture properties and its biotechnological potential.
