Abstract: Chlorella sp. is a type of micro-sized green algae obtained in fresh or marine waters. However, many factors need to evaluate the growth of Chlorella sp. mainly the culture conditions. This study aimed to evaluate the culture conditions in optimizing the growth of Chlorella sp. newly isolated from Bagansiapiapi marine waters. The experiment was carried out at temperature ±25°C, light intensity 2300 Lux using TL-D lamp (36 W). There were six treatments as culture conditions for the cultivation of Chlorella sp.:… Show more

“…In addition to pH, other factors influence the activity metabolism of cell microalgae Chlorella. sp is temperature microalgae growth in this study ranged from 29 -30.5 o C. The optimal temperature range for algae growth is in the range of 25 -35 o C[20]. Therefore, the temperature range in this study is still included in the growth range Chlorella sp.…”

Grey water contains organic matter that is directly disposed to the environment without any treatment previously, will cause pollution and impacting life in the water. Treatment that can be done is using microorganisms. One of its kind is the microalgae Chlorella sp. which utilizes organic matter as a source of nutrients for its growth. In this study, the Kaldness 1 (K1) bio carrier was added as a medium for attaching microorganisms using the Sequencing Batch Biofilm Reactor (SBBR) process. The research objectives were (1) to know the maximum number of Chlorella sp. both attached and suspended in the Sequencing Batch Biofilm Reactor (SBBR), (2) to obtain the best cycle time and stabilization time in the removal of COD, Ammonia, and MLSS in grey water. The research was conducted by varying the stabilization time (1.5; 2 and 2.5 hours) in each cycle for four cycles with a constant variation of charging time 30 minutes, reaction 120 minutes, 45 minutes, separation 45 minutes, and carried out with four cycles, stirring speed at 60 rpm, the concentration of algae suspension in SBBR was 25% and the volume of Kaldness K1 medium was 20%. The results showed the number of microalgae cells Chlorella sp. was suspended and attached to 1.85 x 106 and 1.46 x 106 cells/ml. The best removal of COD, ammonia, and MLSS was found in the stabilization time variation of 1.5 hours in 4 cycles with a removal efficiency of 84% and 76%, respectively, and an increase in the concentration of suspended and attached MLSS by 4780 mg/l and 4720 mg/l. It can be concluded that the faster stabilization time, the more removal efficient will be.

Aquaculture is the farming of aquatic organisms like fish, crustaceans, mollusks, and aquatic plants, which has become a crucial source of protein and income. However, bacterial infections pose a significant challenge to the aquaculture industry and traditional treatments, such as antibiotics and chemicals, have limitations and environmental concerns. Disease prevention and control measures, such as the use of probiotics, vaccines, and biosecurity measures, are essential for the sustainable development of the aquaculture industry. Further research is also needed to develop more effective and sustainable strategies for the prevention and control of bacterial fish pathogens in aquaculture, where alternative treatments such as herbal extracts, essential oils, and probiotics require further investigation for efficacy and safety. Microalgae, particularly Chlorella, have potential applications in various industries such as biofuels, pharmaceuticals, and wastewater treatment. However, their large-scale production and commercialization face challenges. Safety of Chlorella to fish is a crucial issue that requires careful evaluation, with hematology being an essential tool to assess its effects on fish health and physiology. Studies show that Chlorella is safe for fish and does not have adverse effects on growth, survival, or immune system function. Chlorella is a safe and sustainable option for aquaculture, free from harmful chemicals and antibiotics. The Green Water System utilizes Chlorella as a natural filter and nutrient recycler, improving water quality and providing a well-balanced diet for aquatic animals. This eco-friendly approach also enhances fish immune systems, growth rates, and survival rates. The scientometric review shows significant research activity, with Chang JS being a prominent author and People’s R China and the Chinese Academy of Sciences leading in contributions. The use of Chlorella shows promise as an alternative treatment for bacterial fish pathogens in aquaculture due to its antibacterial properties, safety, and sustainability. However, challenges such as cost-effectiveness and standardization need to be addressed for successful implementation in the aquaculture industry.

Probiotics are microorganisms that have benefits when consumed, they can be found in yogurt. Yogurt commercially lack protein; the addition of chlorella is a solution due to chlorella contains high protein. The research aimed to determine the effect of chlorella fortification on the quality characteristics of yogurt and the best concentration of chlorella addition in the manufacturing of yogurt. The experimental method using a non-factorial Completely Randomized Design (CRD) consisting of 4 treatment levels: without the addition of chlorella (PC0), 0.75% of chlorella (PC1), 1% of chlorella (PC2), and 1.25% of chlorella (PC3). The parameters tested in this research were hedonic testing and quality, chemical composition, physical properties, and microbiological assay. The results showed that yogurt fortified with 1% chlorella was most favorable by consumer acceptance, with organoleptic characteristics: green and thick color, slightly characteristic aroma of chlorella, and slightly sour taste typical of chlorella. Meanwhile, the proximate composition of this yogurt contains 81.26% moisture, 3.77% protein, 2.30% fat, 0.89% ash, 1.47% fiber; physical properties of pH 4.65, Aw 0.75, viscosity 205.85 cP; and microbiological value of acid total 1.95%, and lactic acid bacteria 2.1×107 cfu/g. Therefore, the yogurt chlorella is suitable for consumption and can enhance health benefits.
