In this study, the microalgae Haematococcus pluvialis were cultivated in wastewater inoculated into low-density polypropylene plastic air pillows (LDPE-PAPs) under a light stress. The cells irradiated to different stresses using white LED lights (WLs) as control, and broad-spectrum (BLs) test for period of 32 days. It was observed that inoculum (70 × 102 mL-1 cells) H. algal increased almost 30 40 times WL BL, respectively, at day coherent its biomass productivity. Higher lipid concentration up 36.85 μg BL compared 13.215 L-1 dry weight WL. chlorophyll 'a' content 2.6 greater (3.46 mL-1) (1.32 with total carotenoids being about 1.5 on 32. yield red pigment 'Astaxanthin' 27% than presence, including astaxanthin also confirmed by HPLC, whereas fatty acid methyl esters (FAMEs) GC-MS. This study further alongwith stress is suitable biochemical growth good well carotenoid accumulation. Additionally there 46% reduction chemical oxygen demand (COD) far more efficient manner when cultured recycled LDPE-PAP. Such type cultivation made overall process economical upscaling produce value-added products such lipids, pigments, biomass, biofuel commercial applications.

Microalgae are considered to be natural producers of bioactive pigments, with the production pigments from microalgae being a sustainable and economical strategy that promises alleviate growing demand. Chlorophyll, as main pigment photosynthesis, has been widely studied, but its medicinal applications an antioxidant, antibacterial, antitumor reagent still poorly understood. Chlorophyll is most important in plants algae, which not only provides food for organisms throughout biosphere, also plays role variety human man-made applications. The biological activity chlorophyll closely related chemical structure; specific structure offers possibility This paper reviews structural functional roles microalgal chlorophylls, commonly used extraction methods, recent advances medicine, provide theoretical basis standardization commercial application chlorophylls.

The United Nations 2030 Agenda for Sustainable Development has created more pressure on countries and society at large the development of alternative solutions synthetic fossil fuel derived products, thus mitigating climate change environmental hazards. Food wastes microalgae have been studied decades as potential sources several compounds that could be employed in various fields application from pharmaceutical to textile packaging. Although multiple research efforts put towards extracting rich (i.e., phenolic compounds, tocopherols, tocotrienols) these sources, they still remain overlooked two major bioactive pigments, mainly due inefficient extraction processes. Hence, there is a growing need optimized methods while employing non-organic solvent options following main principles green chemistry. This review will focus delivering clear deep analysis existing procedures obtaining pigments food most consumed produced fruit crops world such apples, oranges, cherries, almonds, mangoes, microalgal biomass, giving light drawbacks solved order take full advantage properties present biorefinery sources.

In the energy sector, bioenergy has been utilized as a replacement for non-renewable resources. Due to depletion of resources, mankind may face adversities in future. To overcome these challenges, sustainable and reliable bioenergy-based alternatives are be used. Bioenergy sources bio-based that have become acceptable society their renewability, sustainability, environmentally friendly characteristics, but they still lag market due less cost-effective output upstream downstream processing comparison with age-old fossil fuels. This review provides detailed overview techno-economic life cycle assessment, positioning competition market, strategies might assist them overcoming challenges. Microalgal products lifting at slower rate is almost unnoticeable, assistance becoming better solution against resource future makes quite promising. The new research microalgal biomass conversion biorefinery production, which based on combating pollution reuse waste products, along strategic application competition, also highlighted.
