Treatment of effluents from marine shrimp culture with biofloc technology: Production of Arthrospira (Spirulina) platensis (cyanobacteria) and nutrient removal

Inadequate wastewater management can cause negative impacts on the ecosystem, becoming an obstacle to aquaculture growth. New technologies have been developed to reduce the nutrient load in aquaculture wastewater involving microalgae as phytoremediation agents. In addition to reducing the nutrient load of water bodies, the microalgae‐based phytoremediation can also generate high‐added value biomass. Arthrospira (Spirulina) is a little‐explored genus as a phytoremediation agent for aquaculture wastewater, representing about 30% of the biomass produced in the world that is known for its high concentration of proteins, carotenoids and phycocyanin. Using the aquaculture wastewater is an important strategy to reduce the production costs, obtain high‐added value biomolecules and mitigate the effects of wastewater on the aquatic ecosystem. However, there are few reports of Arthrospira sp. as a remediation agent for aquaculture wastewater that assesses the biochemical composition. This manuscript aimed to review the cellular mechanisms of phytoremediation and the biochemical composition of Arthrospira currently described when grown in aquaculture wastewater.

“…According to Holanda et al (2022), the cultivation of A. platensis in effluent from shrimp production in biofloc, carried out without dilution of wastewater, resulted in low biomass production (0.50 gL −1 ). The difference reported by the authors may be associated with the salinity of the respective effluents (shrimp and fish).…”

“…Boron element in H3BO3 plays a role in maintaining cell pigment because when there is a lack of boron, algae cells will lose their pigment. Phosphorus is an essential element that is very helpful in the formation of proteins and cell metabolism of organisms [8] [13]. Walne fertilizer also contains vitamin B12 which acts as a metalloactivator for aquatic plants.…”

Metalloactivators are organic bonds which contain metal and act as biocatalysts so that they can accelerate cell growth [13]. In addition there is also vitamin B1 which acts as a cofactor for several enzymes involved in metabolism.…”

Microalgae can be used as a good biodiesel raw material because there are quite a lot of oil microalgae, one of which is Spirulina sp. Cultivation Process of Spirulina sp. using seawater media produces more optimal biomass than freshwater media. This study used Bangka Seawater as a growth medium for Spirulina sp., and identification fatty acid of Spirulina extract by GC-MS methode. cell growth of Spirulina sp. on media Bangka seawater using Walne fertilizer can experience an exponential phase until the 9th day due to the addition of Walne fertilizer. Culture with 1 ml of Walne fertilizer had the best growth. The use of Bangka sea water without fertilizer can also grow Spirulina sp with a peak on day 5. The total fatty acid in the hexane extract of Spirulina in this study was 69.60% with similarity indeks above 70%. As many as 33.78% are Saturated Fatty Acids (SFA) such as docosanoic acid, hexadecanoic acid, octadecanoic acid, and hexanedioic acid. While 35.82% are Unsaturated Fatty Acids (UFA). The profile of fatty acid from Bangka seawater media showed that the largest fatty acids contained in Spirulina sp. is palmitic acid (hexadecanoic acid) with presentage 25.21%.

“…To sum up, greenhouse and aquaponic rearing modes are mainly based on heterotrophic and autotrophic bacterial systems, respectively. Previous studies examined the dynamic characteristics of biofloc [ 8 , 9 , 10 ] and circulation modes [ 11 , 12 ] in shrimp aquaculture. It is commonly acknowledged that the microbiome of the host and its environment are pivotal to the host’s health and the stability of the environment [ 13 ].…”

The sustainability of shrimp aquaculture can be achieved through the development of greenhouse and aquaponic rearing modes, which are classified as heterotrophic and autotrophic bacterial aquaculture systems. However, there have been few investigations into the discrepancies between the intestinal and water microbiota of these two rearing methods. In this study, we collected shrimp samples from greenhouse-rearing (WG) and aquaponic-rearing (YG) ponds, and water samples (WE, YE), and investigated the intestinal and water microbiota between the two rearing modes. The results, through alpha and beta diversity analyses, reveal that there was basically no significant difference between shrimp intestine WG and YG (p > 0.05) or between rearing water WE and YE (p > 0.05). At the phylum and genus levels, the common bacteria between WE and WG differed significantly from those of YE and YG. The analysis of the top six phyla shows that Proteobacteria and Patescibacteria were significantly more abundant in the WG group than those in the YG group (p < 0.05). Conversely, Actinobacteriota, Firmicutes, and Verrucomicrobiota were significantly more abundant in the YG group than those in the WG group (p < 0.05). Venn analysis between WE and WG shows that Amaricoccus, Micrococcales, Flavobacteriaceae, and Paracoccus were the dominant bacteria genera, while Acinetobacter, Demequina, and Rheinheimera were the dominant bacteria genera between YE and YG. Pathways such as the biosynthesis of secondary metabolites, microbial metabolism in different environments, and carbon metabolism were significantly more upregulated in WG than those in YG (p < 0.05). In addition, pathways such as sulfate, chloroplast, phototrophy, and the nitrogen metabolism were significantly different between the WE and YE samples. These findings suggest that the greenhouse mode, a typical heterotrophic bacterial model, contains bacterial flora consisting of Amaricoccus, Micrococcales, Flavobacteriaceae, and other bacteria, which is indicative of the biological sludge process. Conversely, the aquaponic mode, an autotrophic bacterial model, was characterized by Acinetobacter, Demequina, Rheinheimera, and other bacteria, signifying the autotrophic biological process. This research provides an extensive understanding of heterotrophic and autotrophic bacterial aquaculture systems.
