Little is known on the antioxidant activity modulation in microalgae, even less diatoms. Antioxidant molecule concentrations and their microalgae has received little attention interconnection between light, photosynthesis, photoprotection, network still unclear. To fill this gap, we selected light as external forcing to drive physiological regulation acclimation costal diatom Skeletonema marinoi. We investigated role of regime concentration ascorbic acid, phenolic compounds among them...
Summary Photosynthesis is known to produce reactive oxygen species together with the transformation of light into biochemical energy. To fill gap knowledge on protective antioxidant network microalgae, a series experiments explore role spectral composition and intensity in modulation photodefence mechanisms developed by coastal diatom Skeletonema marinoi were performed. The total phenolic content, ascorbic acid enzymes glutathione reductase, catalase, ascorbate peroxidase superoxide...
Photochemoprevention can be a valuable approach to counteract the damaging effects of environmental stressors (e.g., UV radiations) on skin. Pigments are bioactive molecules, greatly attractive for biotechnological purposes, and with promising applications human health. In this context, marine microalgae alternative eco-sustainable source pigments that still need taken advantage of. study, comparative in vitro photochemopreventive twenty carcinogenic melanoma model cell B16F0 from UV-induced...
Abstract Microalgal growth maximization is becoming a duty for enhancing the biotechnological fate of these photosynthetic microorganisms. This study, based on an extensive set data, aims to revisit diatom’s cultivation in laboratory with objective increase rate and biomass production. We investigated ability resource requirements coastal diatom Skeletonema marinoi Sarno & Zingone grown conventional f/2 medium aeration two modified conditions: (i) same water movement inside (ii) enriched...
It is noteworthy that phytosterol bioactivities are benefit for human health, promoting their interest to be used in the formulation of enriched and/or functional food ingredients. With growing phytosterols market food, pharmaceuticals or cosmetics, new sources than higher plants-related ones needed, also allow a sustainable and eco-friendly production. Microalgae fill requisite become asset development complements nutraceuticals. The aim this study update integrate knowledge on microalgal –...
Diatoms are one of the most widespread groups microalgae on Earth. They possess extraordinary metabolic capabilities, including a great ability to adapt different light conditions. Recently, we have discovered that diatom Skeletonema marinoi produces natural antioxidant ovothiol B, until then identified only in clams. In this study, investigated light-dependent modulation biosynthesis S. marinoi. were exposed conditions, ranging from prolonged darkness low or high light, also differing...
Microalgae represent a suitable and eco-sustainable resource for human needs thanks to their fast growth ability, together with the great diversity in species intracellular secondary bioactive metabolites. These high-added-value compounds are of interest health or animal feed. The content these valuable compound families is tightly associated microalgal biological state responds environmental cues, e.g., light. Our study develops Biotechnological response curve strategy exploring metabolites...
Microalgal biotechnology is gaining importance. However, key issues in the pipeline from species selection towards large biomass production still require improvements to maximize yield and lower microalgal costs. This study explores a co-cultivation strategy improve bioactive compounds richness of harvested biomass. Based on their biotechnological potential, two diatoms (Skeletonema marinoi, Cyclotella cryptica) one eustigmatophyte (Nannochloropsis oceanica) were grown alone or combination....
Heavy metals (HMs) can induce both chronic and acute harmful effects on marine freshwater biota. The environmental impact of HMs in freshwater, seawater, soil, wastewater be limited using microbes, including microalgae, that are able to remove from matrices. Indeed, they passively adsorb actively accumulate these persistent pollutants within their organelles, limiting detrimental cellular metabolism. Sarno River is a 30 km long stream located Southern Italy, polluted by partially untreated...
Abstract The exploration of natural antioxidants for nutraceuticals and pharmaceuticals industries has recently increased. In this scenario, marine microorganisms, represent underestimated sources bioactive products endowed with beneficial effects on health, that include anti-oxidant, anti-tumor anti-angiogenic activities. Here, we tested the potential cancer preventive activities extracts from coastal diatom Skeletonema marinoi Sarno Zingone (CCMP 2092) prostate cells, in vitro. was grown...
