“…Flasks were incubated in an orbital shaker at 150 rpm at 30 ± 1 °C for 5 days. Then, the produced biomass was vacuum-filtered and washed with deionized distilled water until a pH of ≤ 8 [ 19 ]. For inactivation, biomass was sterilized by autocleavage for 20 min at 121 °C and dried at 60 °C for 24 h. The dried biomass was milled and homogenized using a mortar until a fine powder was obtained.…”

Sorbent materials of biological origin are considered as an alternative to the use of traditional methods in order to remove heavy metals. Interest in using these materials has increased over the past years due to their low cost and friendliness to the environment. The objective of this study was to synthesize and characterize cross-linked beads made of chitosan, alginate, and mycelium of a copper-tolerant strain of Aspergillus australensis. The acute toxicity of the biocomposite beads was assessed using brine shrimp Artemia salina nauplii and the phytotoxicity was determined using lettuce (Lactuca sativa) and chili pepper ’Anaheim’ (Capsicum annuum) seeds. The biosorption capacity for copper removal in simulated wastewater was also evaluated. Results showed that the biosorbent obtained had a maximal adsorption of 26.1 mg of Cu2+ per g of biocomposite, and removal efficiency was around 79%. The toxicity of simulated residual water after treatment with the biocomposite showed low toxicity toward seeds, which was highly dependent on the residual copper concentration. The toxicity of the biocomposite beads to A. salina was considered medium depending on the amount of the biocomposite, which was attributed to low pH. Biocomposite shows promise as biosorbent for the removal process of heavy metals.

“…The removal of metal ions by chemical precipitation or electrochemical treatment when ion concentration is between 1 and 100 mg/L, or when ion product is lower than Ksp is usually inefficient. For example, the limit of copper in drinking water recommended by WHO is 2 mg/L, which is not possible to achieve by precipitation [4,5]. Besides, it is inevitable that new chemicals must be introduced into water systems, including acid and base (pH adjustment), flocculating agents, coagulants, etc., which usually generates new problems.…”

“…Furthermore, some crosslinkers (such as ethylene glycol, glycidyl ether, and glutaric dialdehyde) are toxic and non‐biodegradable in nature 27,28 . In this context, environmentally friendly materials (such as papaya wood, 29 brewer's spent grain, 24 luffa sponge, 26,30 beech sawdust, 31 textile, 32 banana peel, 33 and tea leaf tissue) 34 are recommended for more economical matrices to produce immobilized microbial cells for the water treatment process and they have attracted attention in recent years.…”

BACKGROUND The fluoroquinolone antibiotics in water sources are significant threats to public health, as well as the water ecosystem and water reuse. In this study, the feasibility of the biosorption of ciprofloxacin (CIP) using pine needles biomass‐Gibberella fujikuroi immobilized biocomposite (PNGFB) was promoted. It was prepared by passive cell immobilization onto the lignocellulosic matrix. The suggested biosorbent was characterized by Fourier Transform Infrared (FTIR) analysis, Scanning Electron Microscope (SEM), and zeta potential analysis. Series of batch and continuous mode experiments were conducted. RESULTS The results of both systems showed that the PNGFB was effectively used for the treatment of CIP contamination. The maximum uptake occurred at pH 6.0, 40 min contact time, 1.0 mL min−1 flow rate, and 0.10 g (batch) and 0.20 g (column) PNGFB dosages. Redlich–Peterson isotherm model was the best suited to equilibrium data and the pseudo‐second‐order model predicted the biosorption kinetics. The maximum monolayer biosorption capability was 39.17 mg g−1. The suggested biocomposite also reached CIP removal yields of 64.14% and 53.74% in synthetic hospital effluent and synthetic urine samples containing 100 mg L−1 antibiotic, respectively. The regeneration study indicates that PNGFB retained its high biosorption and desorption yields during five cycles of the biosorption‐desorption. CONCLUSION The findings clearly showed that the PNGFB seems to be an eco‐friendly, effective, economic, and potentially viable biocomposite sorbent for the sustainable removal of CIP contamination. © 2021 Society of Chemical Industry (SCI).
