“…The results show that M SP B-HPO adsorbs Dfc as a monolayer; however, other adsorption surfaces were also available and contributed to the adsorption process, hence, the description by Sips model. This type of adsorption has been reported in other study (Daneshvar et al 2018). The highest Sips adsorption capacity was found to be 100.876 mg g −1 .…”

In this study, Moringa seed powder (M SP ) was pyrolyzed at 450°C to synthesize Moringa seed powder biochar (M SP B) and treated with phosphoric acid (H 3 PO 4 ) to synthesize phosphate-modified Moringa seed powder biochar (M SP B-HPO) as an adsorbent for the removal of diclofenac (Dfc) from aqueous solution. Fourier transform infrared (FTIR) analysis, energy dispersive X-ray spectroscopy (EDS), scanning electron microscopy (SEM), and pH point of zero charge (pH pzc ) were conducted to give more insight into the adsorbent's properties. The SEM analysis showed the transformations in the surface morphology from the parent material to the synthesized materials after the thermal and acid treatment. EDS analysis revealed the variation in the elemental composition of the materials prior to and after adsorption of Dfc ions. The FTIR analysis showed changes and peak intensities of functional groups involved in Dfc removal. The pH pzc showed the charge carried by M SP B-HPO in different pH conditions. Isotherm data best matched the Sips model, and the pseudo-second-order model best described the adsorption kinetics. The maximum adsorption capacity of M SP B-HPO by Sips model was found to be 100.876 mg g −1 .

“…The RE for S. acuminatus was 88% and 69% for nitrogen and phosphorus, respectively, and for the microalgal consortium, it was 90% and 73% for TN and TP, respectively. In comparison, Daneshvar et al [75] evaluated a freshwater microalgae Scenedesmus quadricauda Chodat, nomenillegitimun 1926, and a seawater microalgae Tetraselmis suecica (Kylin) Butcher 1959, in the treatment of dairy wastewater (DWW). The initial concentration of TN and TP in the DWW was 6.14 and 0.09 mM, respectively, for the culture of the marine species, they added 34 g L −1 of sea salt.…”

Cyanobacterial Biomass Produced in the Wastewater of the Dairy Industry and Its Evaluation in Anaerobic Co-Digestion with Cattle Manure for Enhanced Methane Production

The unique perspective that microalgae biomass presents for bioenergy production is currently being strongly considered. This type of biomass production involves large amounts of nutrients, due to nitrogen and phosphorous fertilizers, which impose production limitations. A viable alternative to fertilizers is wastewater, rich in essential nutrients (carbon, nitrogen, phosphorus, potassium). Therefore, Arthrospira platensis was cultivated in 150 mL photobioreactors with 70% (v/v) with the wastewater from a dairy industry, under a regime of light:dark cycles (12 h:12 h), with an irradiance of 140 μmol m−2 s−1 photon. The discontinuous cultures were inoculated with an average concentration of chlorophyll-a of 13.19 ± 0.19 mg L−1. High biomass productivity was achieved in the cultures with wastewater from the dairy industry (1.1 ± 0.02 g L−1 d−1). This biomass was subjected to thermal and physical treatments, to be used in co-digestion with cattle manure. Co-digestion was carried out in a mesophilic regime (35 °C) with a C: N ratio of 19:1, reaching a high methane yield of 482.54 ± 8.27 mL of CH4 g−1 volatile solids (VS), compared with control (cattle manure). The results demonstrate the effectiveness of the use of cyanobacterial biomass grown in wastewater to obtain bioenergy.

“…Table 1 presents a set of desirable features of microalgae and their main advantages. Their short life cycle (hours to days), high nutrient absorption rate [26], and capability to grow in both fresh and marine waters [1] allow researchers to process the screening of several species in miniaturised systems, reducing development costs and intensifying process design. These features, associated with their high photosynthetic efficiency and possibility of cultivation in either mixotrophic or heterotrophic modes are their main advantages compared to other photosynthetic organisms [27].…”

“…Microalgae, or microphytes, are defined as aquatic unicellular microorganisms that can be both found in freshwater and marine systems [1]; are capable of photosynthesis [2]; and found in many shapes and sizes, ranging from three to ten micrometres [3]. Cyanobacteria, also called blue-green algae, are frequently considered part of the same group due to their physiological characteristics and 'photofermentation' feature [4].…”

Microalgae are aquatic unicellular microorganisms that can be found both in freshwater and marine systems; are capable of photosynthesis; and can grow as individual cells or associated in chains or small colonies. Microalgae cultivation has gained large momentum among researchers in the past decades due to their ability to produce value metabolites, remarkable photosynthetic efficiency, and versatile nature. The wide technological potential, and thus increasing amount of scattered knowledge, may become the very first barrier that a post graduating student, or any non-specialist reader, will face when introduced to the subject. In this review paper, we access the core aspects of microalgae technology, covering their main characteristics, and comprehensively presenting the main features of their various cultivation modes and biological activity from metabolites.
