“…HHEP 5 removed 99% of phosphorus and 99.37% of nitrate isolated from the mariculture effluents 60 . Wang et al demonstrated that the removal rate of total nitrogen and total phosphorus were 78.3% and 87.2% correspondingly after the treatment by Chlorella-exiguobacterium from the piggery wastewater treatment 61 .…”

The bioremediation of beverage (treated and untreated) effluent was investigated in the current study by using the potential strains of Bacillus sp. (BK1) and Aspergillus sp. (BK2). Effluent was collected from the beverage industry (initial concentration of nitrogen were 3200 ± 0.5 mg/L and 4400 ± 0.6 mg/L whereas phosphorus were 4400 ± 2 mg/L and 2600 ± 1 mg/L in treated and untreated effluent correspondingly). Further, the BK1 and BK2 exhibited high removal competence after 1 week of incubation; BK1 removed phosphorus 99.95 ± 0.7% and BK2 95.69 ± 1% in treated effluent while nitrogen removed about 99.90 ± 0.4% by BK1 and 81.25 ± 0.8% by BK2 (initial concentration of phosphorus 4400 ± 2 mg/L and nitrogen 3200 ± 0.5 mg/L). Next, in the untreated effluent BK1 removed 99.81 ± 1% and BK2 99.85 ± 0.8% of phosphorus while removed nitrogen 99.93 ± 0.5% by BK1 and 99.95 ± 1.2% by BK2 correspondingly, (initial concentration of phosphorus 2600 ± 1 mg/L and nitrogen 4400 ± 0.6 mg/L). The physiochemical composition of sample such as pH, total carbohydrates, total proteins, total solids of treated and untreated effluent were also analysed before and after treatment of both the samples. BK1 and BK2 increased the pH by 8.94 ± 0.3 and 9.5 ± 0.4 correspondingly in treated effluent whereas 6.34 ± 0.5 and 7.5 ± 0.2 correspondingly in untreated effluent (initial pH of treated and untreated effluent 7.07 ± 0.8 and 4.85 ± 0.3 correspondingly). Total Carbohydrates removed about 17,440 ± 4.6 mg/L and 10,680 ± 3.2 mg/L by BK1 and BK2 correspondingly in treated effluent whereas 18,050 ± 3.5 mg/L and 18,340 ± 2.3 mg/L correspondingly in untreated effluent (initial concentration of treated and untreated effluent 25,780 ± 1.6 mg/L and 35,000 ± 1.5 mg/L correspondingly) while BK1 and BK2 removed total proteins by 30.336 ± 4.6 mg/L and 40.417 ± 2.3 mg/L correspondingly in treated effluent whereas 18.929 ± 1.2 mg/L and 17.526 ± 0.8 mg/L correspondingly in untreated effluent (initial concentration of treated and untreated effluent 49.225 ± 1.5 mg/L and 20.565 ± 1 mg/L correspondingly). Next, total solids removed by BK1 and BK2 2.5 ± 0.3 mg/L and 1.6 ± 0.6 mg/L correspondingly in treated effluent whereas 5.5 ± 0.8 mg/L and 4.6 ± 0.6 mg/L in untreated effluent (initial concentration of treated and untreated effluent 5.6 ± 1.5 mg/L and 9.48 ± 1.2 mg/L correspondingly). Both the strains BK1 and BK2 are highly efficient in the nitrogen and phosphorus removal therefore this strain may be applied for the potential remediation.

“…Algal-bacterial processes have been successfully tested for the treatment of domestic wastewater [81], centrates [86], vinasse [87] and piggery wastewater [88]. Wang and colleagues evaluated a Chlorella-Exiguo bacterium consortia cultured in a column photobioreactor for piggery wastewater purification [89]. They showed that the rates of contaminant removal by the Chlorella-bacteria consortium were higher than that of the pure Chlorella and bacterial monocultures.…”

“…They showed that the rates of contaminant removal by the Chlorella-bacteria consortium were higher than that of the pure Chlorella and bacterial monocultures. The results indicated that there is synergistic interactions of cell growth promotion and the exchange of carbon and oxygen between microalgae and bacteria [89]. Posadas et al studied the photosynthetic biogas upgrading coupled with centrate treatment at pilot scale under outdoors conditions.…”

Photoautotrophs–Bacteria Co-Cultures: Advances, Challenges and Applications

Photosynthetic microorganisms are among the fundamental living organisms exploited for millennia in many industrial applications, including the food chain, thanks to their adaptable behavior and intrinsic proprieties. The great multipotency of these photoautotroph microorganisms has been described through their attitude to become biofarm for the production of value-added compounds to develop functional foods and personalized drugs. Furthermore, such biological systems demonstrated their potential for green energy production (e.g., biofuel and green nanomaterials). In particular, the exploitation of photoautotrophs represents a concrete biorefinery system toward sustainability, currently a highly sought-after concept at the industrial level and for the environmental protection. However, technical and economic issues have been highlighted in the literature, and in particular, challenges and limitations have been identified. In this context, a new perspective has been recently considered to offer solutions and advances for the biomanufacturing of photosynthetic materials: the co-culture of photoautotrophs and bacteria. The rational of this review is to describe the recently released information regarding this microbial consortium, analyzing the critical issues, the strengths and the next challenges to be faced for the intentions attainment.

“…Las aguas residuales producto de las industrias agropecuarias se caracterizan por altas cargas de materia orgánica, nitrógeno amoniacal y fósforo. Estos compuestos constituyen un factor crítico para problemáticas ambientales como la erosión del suelo, la contaminación atmosférica producto de la volatilización de amoníaco y sulfuro de hidrógeno y la eutrofización de cuerpos de agua (Mousavi et al, 2020;Wang et al, 2020). En la actualidad, las aguas residuales se suelen someter a procesos oxidativos en lagunas para luego ser tratadas en lagunas anaeróbicas y, como etapa final, en lagunas aérobicas facultativas o reactores de película con lecho móvil (Wang et al, 2020), donde las microalgas son las protagonistas, ya que no solo gobiernan el consumo de CO2 sino que también brindan una alternativa segura y rentable a la aireación mecánica .…”

Las microalgas juegan un papel esencial en estas últimas etapas, demostrando una notable capacidad de absorber nitrógeno y fósforo inorgánicos de forma eficiente, puesto que en este punto los contaminantes han sido degradados y mineralizados por acción de microorganismos heterotróficos (Nur & Buma, 2019;Wang et al, 2020).…”

Colombia es uno de los mayores productores de café en el mundo, con un mercado que superó los 13,9 millones de sacos en 2020. Sin embargo, en el proceso de beneficio húmedo del café se emplean grandes cantidades de agua, aproximadamente 4.154.354 m3, en las fases de despulpado, lavado y transporte del grano, generando aguas residuales contaminadas que tienen poco tratamiento antes de ser vertidas a las fuentes hídricas. En el presente trabajo se buscó aislar especies de microalgas que crezcan en estos ambientes, utilizar estas especies en procesos de depuración de aguas residuales del proceso de lavado del café y buscar una aplicación de la biomasa resultante. Para la obtención de las cepas de microalgas se utilizaron técnicas de agotamiento. Con el fin de evaluar su capacidad de depuración, estas fueron cultivadas en agua residual de diferentes concentraciones bajo condiciones de laboratorio, determinando la remoción de materia orgánica. Adicionalmente, se caracterizó bioquímicamente la biomasa algal para determinar posibles usos biotecnológicos o industriales. Se encontró dos Chloroficeaes cocales, Parachlorella kessreli y Desmodesmus armatus, las cuales demostraron una alta eficiencia en la remoción de nitrógeno total (> 50 %) y fósforo total (> 70 %), así como una disminución significativa de la DQO (> 70 %) en los mejores tratamientos. Finalmente, se encontró para Parachlorella kessreli alta producción de lípidos y para Desmodesmus armatus alta producción de proteína.
