In modeling of the outdoor or indoor algal culture system, growth rate and biomass productivity are predicted as a function of light [62]. Astaxanthins are multifunctional carotenoids usually obtained from Haematoccocus pluvialis. It has been reported that the genetically engineered strain of P. tricornutum produce a maximum yield of 36.5 and 23.6% of DHA and EPA per total fatty acids of biomass indicating its feasibility for production of EPA and DHA at commercial scale [199]. Synthesis of sterols is also influenced by a number of factors in microalgae affecting the final yield. The majority of the reported studies analysed the preventive effects because algae were administered to animals concurrent with the diet that induced NAFLD. Recall, the ash contents for microalgae and macroalgae are 17.5 and 38.0 wt%, respectively [6 . The present review describes the advantages of microalgae for the production of biofuels and various bioactive compounds and discusses culturing parameters. All macroalgae are photosynthetic and therefore depend on the sun's energy for food. The algal sugars are excellent materials for bioethanol production. In conclusion, Sarconema filiforme supplementation modulated gut microbiota without changing the Firmicutes/Bacteroidetes ratio. Mice were distributed into three experimental groups: control group (fed with a standard diet), HFD group (fed with a diet containing 60% of energy as fat) and HFD + CL fed with the same high-fat diet and 250 mg/kg body weight of the algae, administered by oral gavage, for ten weeks. ROS and NOS have also been reported to be involved in the progression of obesity. Pulz O, Gross W. Valuable products from biotechnology of microalgae. In nature, they are mostly aquatic and autotrophic. The rapid growing population of the world continuously increases the global demand for fuel energy. Nevertheless, both macroalgae and microalgae produce oxygen and contribute to food production in aquatic environments.

Santanu Dasgupta, in Journal of Environmental Management, 2021. These compounds are reportedly crucial for lowering fat in high-fat mouse feeds [253] In obese mice, fucoxanthin suppresses adiposity by activating the mitochondrial protein UCP1 (Uncoupling protein1) in abdominal WAT [254] Fucoxanthin significantly reduced body fat in obese individuals in a clinical trial by Abidov et al. Appropriate penetration and uniform distribution of light is also needed to avoid photoinhibition, also called the self-shading effect, in which algae at lower layers are shaded from the light by upper layers. and transmitted securely. Epub 2016 Jul 19. Bothast RJ, Schlicher MA. The reported data described in the present review show that there is scientific evidence supporting the beneficial effects of microalgae and the different types of macroalgae (green, red and brown) on liver steatosis in rodent models (Figure 1). Some microalgae also produce compounds that have antifungal activities [212]. Microalgae metabolites: a rich source for food and medicine. Moreover, CCAAT/enhancer-binding protein alpha (C/ebp) gene expression was higher in the mice treated with the alga than in the other groups. The USA have 187 commercial bioethanol plants, which mainly produce bioethanol from corn grain [31]. The .gov means its official. All the data and materials can be found main text. The overgrowth of adipose tissue occurs because of adipogenesis, so obesity can be controlled by guarding the cells against adipogenesis [250]. Algae is a general term for phylogenetically unrelated organisms that utilize photosynthesis and/or possess plastids. 0.5g/l nitrogen has been proved to be optimum concentration for Chlorella vulgaris at which it produces 3.43g/l biomass [72]. [74] experimentally proved that a light intensity of 100mol/m2/s is optimum for some microalgal species. Juneja A, Ceballos RM, Murthy GS.

Chng LM, Lee KT, Chan DJ. and L.A.; writing-review and editing, M.P.P. 618 E GERMANN RD Microalgae are referred as photosynthetically driven single or multi-cellular living being, the habitat of moist environment either on the solid mud or float on various water types, e.g., fresh water, marine water, wastewater with the presence of sunlight, or artificial light. If all the other requirements are met but there is no mixing, biomass productivity will be lowered significantly. Algal nutrition. Dunaliella salina also produces compounds that are active against several bacterial and fungus strains (e.g., Staphylococcus aureus, Escherichia coli, Candida albicans, Psuedomonas aeruginosa, Aspergillus niger) [259]. Red algae natural products for prevention of lipopolysaccharides (LPS)-induced liver and kidney inflammation and injuries. Macroalgae are one of the two major types of algae. Algae-based biofuels attract incentives and investments. Treatment of influenza A (H1N1) virus infections in mice and ferrets with cyanovirin-N. Arya V, Gupta VK. Urea is also a suitable source and a cost-effective alternative to other inorganic nitrogen sources. Hydrolysis with acids or enzymes can release fermentable sugars from algal carbohydrates for bioethanol production [8, 110, 111]. Research has revealed various anti-hyperlidimic and fat-lowering agents from natural sources, such as medicinal plants. Considering that several components of algae are able to modify microbiota composition [37,38,39], an interesting field of future research is to establish the relationship between these modifications and the improvement of NAFLD produced by algae. Nakashima et al. Researchers need to develop feasible and economical methods of biomass pretreatment for bioethanol production, optimized for different feedstocks. Macroalgae serve as the base of our water's food chain, providing food, oxygen and habitat for thousands of aquatic inhabitants. PMC legacy view Macroalgae have a long list of health benefits for humans, are potential biofuels, and have been found beneficial in other industries. When splenocytes were isolated, mice receiving Spirulina platensis supplementation had significantly lower gene expression level of basal Il-1 and a trend to decreased expression of Il-6. Algae are large polyphyletic, photosynthetic organisms that contain a diverse group of species. However, unlike macroalgae, the microalgae-biopesticides role is effective against bacteria, fungi and oomycetes, and the exact molecule involved is unknown. We are experimenting with display styles that make it easier to read articles in PMC. Smee DF, Bailey KW, Wong MH, et al.

[71] reported that microcystis aeruginosa give maximum biomass and carbohydrates productivity at red LED light of about 5000lx. The bloom is also responsible for shellfish poisoning, due to the presence of toxins. Global bioethanol production has vigorously increased from 1 billion to 39billionl within a few years and will reach 100 billionl soon [38]. Because of its sustainability, it has the potential to be a long-term solution for fuel, food, feed, agriculture, and other products. The fermentation process should be carried out in an aseptic environment to avoid contamination, which greatly reduces final yields [40]. Figure2 presents carbohydrate-rich microalgae species suitable for algal bioethanol production. Marine natural products and their potential applications as anti-infective agents (review), Washida K, Koyama T, Yamada K, Kitab M, Urmura D, et al. The Microcystis sp. Antimycotic activities have been reported for karatungiols, a group of compounds synthesized by the dinoflagellate Amphidinium [215]. Pathologic angiogenesis promotes tumors and helps them to grow [230] Therefore, angiogenesis is considered the cause of tumor growth and expansion in cancer. They need light as an energy source to convert the absorbed water and CO2 into biomass through photosynthesis [49]. Different ways of algae administration have been used in the published studies, included in the diet, included in the drinking water or administered by oral gavage, and all of them have been adequate to show the beneficial effects of algae. g Chemical structure of microcystin-LR, produced by the blooming Microcystis aeruginosa, The promising future of microalgae: current status, challenges, and optimization of a sustainable and renewable industry for biofuels, feed, and other products.

Fucoxanthin and its metabolite, fucoxanthinol, suppress adipocyte differentiation in 3T3-L1 cells. Many reports indicate the potential of natural products, including those produced by microalgae, to treat cancer and tumors by inhibiting angiogenesis. So, this is the key difference between macroalgae and microalgae. The decline in photosynthesis results in a decreased growth rate [81]. Livers displayed an abnormal histopathological appearance as portal lymphoplasmacytic, inflammatory infiltrates, hydropic alterations, portal lymph plasmatic infiltrate and parenchymal hydropic alterations with apoptosis and binucleated cells were found in the induction group. Open culture systems are comparatively inexpensive, but they become easily contaminated. Using the same brown alga, Li et al. Researchers are looking for antioxidants from natural sources, such as medicinal plants. FOIA Kang et al. Cornish M, Garbary D. Antioxidants from macroalgae: potential applications in human health and nutrition. However, their outer covering is made of a different substance and have a rigid body. The positive effects were demonstrated using a wide range of doses, from 7.5 to 300 mg/kg body weight/day or from 1 to 10% in the diet, and experimental periods ranged from 3 to 16 weeks. Meroni M., Longo M., Rustichelli A., Dongiovanni P. Nutrition and Genetics in NAFLD: The Perfect Binomium. This is because seagrasses are rooted to the substrate and as such . Several types of microorganisms, such as bacteria, yeasts, and fungi, have been identified for their potential for fermenting sugars to bioethanol [123125]. The solid residue yield decreased with increasing the microalgae/macroalgae mass ratio. Microalgae also have the potential to play a major role in climate change mitigation through their carbon fixation. Individuals in the intervention group (29) received 1200 mg/day of Chlorella vulgaris dispensed in four tablets of 300 mg and 400 mg/day of vitamin E, whereas the placebo group (26) received 400 mg/day of vitamin E and four placebos for eight weeks.
