“…and 57.1% in algae mix (Figure 1b). This result contrasted with PO4-P removal with Chlorella vulgaris of previous studies, which reduced only 4.30% of PO4-P [11]. The results of other studies mentioned the efficiency value of Chlorella sp.…”

Domestic wastewater provides the largest contribution to pollution both in terms of quantity and quality. Therefore, before being discharged into the environment, wastewater needs to be managed first. This study used the cultivation of microalgae Chlorella sp. and algae mix to manage domestic wastewater. The reactor used in the study was a 3L volume of water. The cultivation process was assisted by UV-A and UV-B with the air flow rate as much as 1.2 L/min. Pollutant parameters being focused on were NH3-N and PO4-P nutrient parameters. Allowance for NH3-N by Chlorella sp. and algae mix were 54.9% and 49%, respectively. Allowance for PO4-P by Chlorella sp. and algae mix were 70.2% and 57.1% while biomass of Chlorella sp. and algae mix increased 85.5% and 98.9%. Specific growth rate of Chlorella sp. and algae mix were 0.025 h-1 and 0.027 h-1. As a control on biomass growth, turbidity value in the study also increased.

“…reaching 98.7-99.8% with piggery wastewaters media [10] and 80.62% with domestic wastewater media [9]. The same results were produced in swine wastewater treatment with Chlorella vulgaris producing 40-90% NH3-N removal [11]. This study less of NH3-N removal because the COD/NH3N ratio very high with 678 mg/L/7,81 mg/L.…”

“…There are a few experimental reports that have been working on different consortia of microalga species and bacteria for urban and industrial wastewater treatments [2,10]. The C. vulgaris and P. putida consortium inherently has shown to be a good nutrient and organic contaminants removal option in synthetic municipal wastewater compared to axenic cultures [11,12]. Lananan, et al 2014, reported a removal efficiency up to 99.15% of the total phosphorus concentration in domestic wastewater treatment by using Chlorella with an effective microorganism (EM-1) co-culture [13].…”

Anthropogenic activities have increased the amount of urban wastewater discharged into natural aquatic reservoirs containing a high amount of nutrients such as phosphorus (Pi and PO 4 − 3 ), nitrogen (NH 3 and NO 3 − ) and organic contaminants. Most of the urban wastewater in Mexico do not receive any treatment to remove nutrients. Several studies have reported that an alternative to reduce those contaminants is using consortiums of microalgae and endogenous bacteria. In this research, a genome-scale biochemical reaction network is reconstructed for the co-culture between the microalga Chlorella vulgaris and the bacterium Pseudomonas aeruginosa. Metabolic Pathway Analysis (MPA), is applied to understand the metabolic capabilities of the co-culture and to elucidate the best conditions in removing nutrients. Theoretical yields for phosphorus removal under photoheterotrophic conditions are calculated, determining their values as 0.042 mmol of PO 4 − 3 per g DW of C. vulgaris, 19.43 mmol of phosphorus (Pi) per g DW of C. vulgaris and 4.90 mmol of phosphorus (Pi) per g DW of P. aeruginosa. Similarly, according to the genome-scale biochemical reaction network the theoretical yields for nitrogen removal are 10.3 mmol of NH 3 per g DW of P. aeruginosa and 7.19 mmol of NO 3 − per g DW of C. vulgaris. Thus, this research proves the metabolic capacity of these microorganisms in removing nutrients and their theoretical yields are calculated.

“…Thus, calculating and analyzing ExPas from the metabolic network of the consortium between C. vulgaris and P. aeruginosa, it is possible to estimate their phenotypic potential under different schemes. Our research group has been working in the evaluation of nutrients of removal by using different microorganisms and the consortium between them [13]. Consequently, this project provides a fundamental approach to enhance our understanding of biological system where microalgae and bacteria coexist as it occurs in most wastewater treatment.…”

Anthropogenic activities have increased the amount of urban wastewater discharged into natural aquatic reservoirs confining in them a high amount of nutrients and organics contaminants. Several studies have reported that an alternative to reduce those contaminants is using consortiums of microalgae and endogenous bacteria. In this research, a genome-scale biochemical reaction network is reconstructed for the co-culture between the microalga Chlorella vulgaris and the bacterium Pesudomonas aeruginosa. Metabolic Pathway Analysis (MPA), is applied to understand the metabolic capabilities of the co-culture and to elucidate the best conditions in removing nutrients such as Phosphorus (inorganic phosphorous and phosphate) and Nitrogen (nitrates and ammonia). Theoretical yields for Phosphorus removal under photoheterotrophic conditions are calculated, determining their values as 0.042 mmol of PO4/ g DW of C. vulgaris, 19.53 mmol of inorganic Phosphorus /g DW of C. vulgaris and 4.90 mmol of inorganic Phosphorus/ g DW of P. aeruginosa. Similarly, according to the genome-scale biochemical reaction network the theoretical yields for Nitrogen removal are 10.3 mmol of NH3/g DW of P. aeruginosa and 7.19 mmol of NO3 /g DW of C. vulgaris. Thus, this research proves the metabolic capacity of these microorganisms in removing nutrients and their theoretical yields are calculated.
