“…Another factor which affects microalgae growth and cell content is light (Kumar et al 2011;Pérez-Pazos and Fernández-Izquierdo 2011). The variation in light intensity and photoperiod might influence lipid production in the microalgae cells, because lipoid production is associated with carbon content (Pérez-Pazos and Fernández-Izquierdo 2011).…”

Microalgae have high nutritional values for aquatic organisms compared to fish meal, because microalgae cells are rich in proteins, lipids, and carbohydrates. However, the high cost for the commercial production of microalgae biomass using fresh water or artificial media limits its use as fish feed. Few studies have investigated the potential of wet market wastewater and slaughterhouse wastewater for the production of microalgae biomass. Hence, this study aims to highlight the potential of these types of wastewater as an alternative superior medium for microalgae biomass as they contain high levels of nutrients required for microalgae growth. This paper focuses on the benefits of microalgae biomass produced during the phycoremediation of wet market wastewater and slaughterhouse wastewater as fish feed. The extraction techniques for lipids and proteins as well as the studies conducted on the use of microalgae biomass as fish feed were reviewed. The results showed that microalgae biomass can be used as fish feed due to feed utilisation efficiency, physiological activity, increased resistance for several diseases, improved stress response, and improved protein retention.

“…However, excessive light exposure can cause light prohibition in microalgae (Ren 2014). Kumar et al (2011) found that the maximum light intensity to produce carotenoid in Spirulina platensis was 3500 lx, while the highest amount of biomass was obtained at 2000 lx (0.71 g/L).…”

“…Also, Richardson et al (1983) reported pigment content and photosynthetic activity of microalgae cultured significantly changed due to differences in light intensities. In addition, Kumar et al (2011) reported that Spirulina platensis carotenoid content increased with increasing light. This is a form of adaptation mechanisms of microalgae for photo-protection.…”

Nannochloropsis sp. has been identified as sources of live feed and pigment in aquaculture. To increase the production, the optimal environmental conditions for microalgae are required. Light intensity is one of the important factors that significantly affects the biomass and pigment of microalgae. The study aimed to determine the effect of light intensity (1,500; 3,000; and 4,500 lux) on growth, biomass production, chlorophyll-a, and carotenoid content of Nannochloropsis sp. strain BJ17. The results showed that different light intensities significantly affected the growth, biomass, chlorophyll-a and carotenoid contents of Nannochloropsis sp. strain BJ17. Increasing light intensity resulted in the increase of the growth rate, biomass, chlorophyll-a, and carotenoid contents of Nannochloropsis sp. strain BJ17. The cell achieved the highest specific growth rate of 1.729 /day and the cell concentration of 43.333×10 6 cell/mL at a light intensity of 4,500 lux. The highest chlorophyll-a and carotenoid concentrations of algae were obtained at 4,500 lux (8.304 µg/mL and 3.892 µg/mL, respectively). This study suggested that increasing light intensity led to the increase in the growth, biomass, chlorophyll-a, and carotenoid content of Nannochloropsis sp. strain BJ17.Keywords: carotenoid, chlorophyll, biomass, growth rate, light intensity ABSTRAK Nannochloropsis sp. diketahui sebagai sumber pakan alami dan pigmen pada budidaya perikanan. Budidaya pada kondisi lingkungan yang optimal diperlukan untuk meningkatkan produksi mikroalga. Intensitas cahaya merupakan salah satu faktor esensial yang secara signifikan mempengaruhi biomassa dan pigmen mikroalga. Tujuan penelitian ini adalah untuk menentukan pengaruh intensitas cahaya yang berbeda (1.500, 3.000, and 4.500 lux) terhadap pertumbuhan, produksi biomassa, klorofil-a, dan karotenoid Nannochloropsis sp. strain BJ17. Hasil menunjukkan bahwa intensitas cahaya yang berbeda berpengaruh secara signifikan terhadap pertumbuhan, biomassa dan klorofil-a dan karotenoid Nannochloropsis sp. strain BJ17. Semakin tinggi intensitas cahaya maka laju pertumbuhan, biomassa, kandungan klorofil-a dan total karotenoid Nannochloropsis sp. strain BJ17 semakin tinggi. Laju pertumbuhan spesifik tertinggi 1,729 /hari dan konsentrasi sel maksimum tertinggi 43,333×10 6 sel/ mL dihasilkan pada intensitas cahaya 4.500 lux. Konsentrasi klorofil-a (8,304 µg/mL) dan karotenoid (3,892 µg/mL) tertinggi juga diperoleh pada intensitas cahaya 4.500 lux. Studi ini menunjukkan bahwa peningkatan intensitas cahaya berperan dalam meningkatkan pertumbuhan, produksi biomassa, klorofil-a, dan karotenoid Nannochloropsis sp. strain BJ17.

The escalating levels of antibiotic resistance among pathogenic bacteria and the side effects of chemotherapeutic drugs in use forced the efforts of scientists to search for natural antimicrobial and anticancer substances with novel structures and unique mechanism of action. Focusing on bioproducts, recent trends in drug research have shown that microalgae (including the cyanobacteria) are promising organisms to furnish novel and safer biologically active compounds. Many microalgal metabolites have been found to possess potent antibacterial, antifungal, antiviral, anticancer and antiinflammatory activities, as well as antioxidant, enzyme inhibiting and immunostimulating properties. In this paper, the studies on the biological activity of microalgae associated with potential medical and pharmaceutical applications are briefly presented. Attention is focused on the impact of cultivation temperature, irradiance and growth stage on the biomass accumulation, activity and pathways of cell metabolism and the possibilities of using these variable factors to increase the diversity and quantity of biologically active substances synthesized by microalgae.
