The biomass obtained from microalgae, such as Chlorella, is used to make dietary products, supplements and pharmaceuticals. However, microalgae are produced very far from consumption places. One of the most usual distribution forms is as a dry product, a process that entails high production costs and leads to the loss of certain nutritional properties. Therefore, the aim of this study was to evaluate alternative preservation strategies for microalgae Chlorella other than dehydration and freezing. To that end, sterilization, acidification, and packaging material were analyzed during 2 months of storage under different temperature and light exposure conditions. The results showed that color was modified considerably by sterilization, regardless of light exposure and type of package, whereas citric acid preserved color, especially at low storage temperatures. Furthermore, the study shows that acidification with 3.5% of citric acid and vacuum packaging are the recommended treatment for microalgae, without the need for cold storage. Practical applications Stabilization of microalgae Chlorella from production to consumption places could increase the possibilities of commercialization of this product, recently labeled “superfood” by the UN Food and Agriculture Organization. In order to preserve all their nutritional properties for at least 2 months, acidification with 3.5% of citric acid and vacuum packaging are the recommended treatments, without the need for cold storage.

“…Most of Chlorella species survived and cultivated in freshwater conditions. However, several reports and studies on isolation showed the versatility and the availability of Chlorella species to adapt and survive in marine environment [29,30]. Other result from NCBI also showed that several microalgae which were isolated from South China Sea were confirmed to be Chlorella species.…”

Carbon capture and storage (CCS) through biological approach has attracted much attention as global warming and climate change issue becomes a worldwide agenda. Energy production industry from coal in Malaysia produced 50.661 million metric tons of carbon dioxide in 2012, and the trend showed it will keep increasing year by year. CCS through biological approach can be done by microalgae which are versatile microorganism which perform photosynthesis process that can store CO2 in the biomass form. In this study, microalgae strains were isolated from the native environment nearby a coal-fired power plant, where samples were collected in different canal in which pre-treated flue gases are discharged. The microalgae strains were identified by both morphological and molecular approaches. Result from 18s rRNA gene sequencing showed that the isolated strains is Chlorella sp. with similarity 99% with Chlorella sp. SAG 211-18. The identified strains of microalgae then cultivated with three concentration of CO2 (ambient air, 1% and 5%) and the growth rate showed 0.4017 day -1 , 0.5752 day -1 and 0.4427 day -1respectively. Different concentration of CO2 (ambient air, 1% and 5%) showed that the isolated strains yielded 1.005gL -1 , 1.101gL -1 and 1.035gL -1 respectively. This study also showed that with different concentration of CO2, the sequestration rate is ranging from 1% to 4.3%.Keywords: microalgae, isolation, purification, DNA sequencing Abstrak Pemerangkapan dan penyimpanan karbon (CCS) melalui pendekatan biologi telah menarik minat pengkaji disebabkan masalah pemanasan dan perubahan iklim global.

“…The mechanism of excess energy dissipation in DSSC can be understood from the following reported works. Nurachman et al [108] used beta-carotene as a dye in fabricating DSSC. The role of B carotene is to harvest light energy and to transfer the photons from the conjugated double bonds in carotene to the TiO 2 molecules directly (similar to chlorophylls in plants) and then concentrate the energy in conduction band of TiO 2 to release electrons.…”

Summary The advancements in the generation of solar cells have created a landmark to design a cost‐effective, less weight, biocompatible, and environmental‐friendly solar cell. Dye‐sensitized solar cells (DSSCs) have become a topic of significant research in the recent years because of their imperative role in the zone of harvesting energy from the renewable source, and it appears to be a promising candidate for the triumph because of its low cost and ease of preparation. The use of synthetic dyes as a sensitizer for DSSC provides better efficiency and high durability. Unfortunately, they suffer from several margins such as higher cost and usage of toxic materials. These downsides have opened up for alternative sensitizer such as biocompatible natural dyes. Natural dyes contain plant pigments such as carotenoid, flavonoid, betalains, and chlorophyll that act as sensitizers (dye) for DSSC. But, the efficiency of natural dyes is not up to the mark mainly due to photoinstability of natural dye in the presence of sunlight that leads to photodegradation. The stability issues are mainly due to interaction of natural dyes with photoelectrode. The photoelectrodes in DSSC are semiconductor materials with superior characteristic of photocatalytic activity (PCA). The PCA of titanium dioxide (TiO2) generates high energetic free electrons on the surface of film that produce free radical ions in contact with moisture. These free radical ions readily degrade the organic matter present nearby (natural dye in DSSC). Thus, the PCA of photoelectrode is responsible for the photodegradation of dyes causing photoinstability. The main objective of this review is to study the photoinstability of natural dyes in DSSC. In this regard, the DSSC is concentrated into sections, and the stability issues due to PCA of photoelectrode are studied individually in the view of considering the DSSC operating with iodide‐based electrolytes and platinum as counter electrode only. Various algae groups are featured as a study tool to overview the dye interaction with photoelectrode. It highlights the application of Z‐scheme of photosynthesis to DSSC to have a broader perception on the working of DSSC and also shows some of the ways for improving the stability of dyes by suppressing or reducing the PCA of photoelectrode.
