“…Like any other medicinal mushrooms, the Ganoderma species feed by the absorption of nutrients from their growth surroundings, such as synthetic nitrogen (N) 23 , ammonia nitrogen (NH 3 –N) 29 , atmospheric N 30 , and industrial dyes 31 . In a wastewater treatment application, adsorption has long been used for NH 3 –N removal 32 using costly non-biological materials, and is insufficient to meet the current market demand.…”

The fluctuation of domestic wastewater characteristic inhibits the current conventional microbial-based treatment. The bioremediation fungi has received attention and reported to be an effective alternative to treat industrial wastewater. Similar efficient performance is envisaged for domestic wastewater whereby assessed performance of fungi for varying carbon-to-nitrogen ratios in domestic wastewater is crucial. Thus, the performance of pre-grown wild-Serbian Ganoderma lucidum mycelial pellets (GLMPs) was evaluated on four different synthetic domestic wastewaters under different conditions of initial pH (pH 4, 5, and 7) and chemical oxygen demand (COD) to nitrogen (COD/N) ratio of 3.6:1, 7.1:1, 14.2:1, and 17.8:1 (C3.6N1, C7.1N1, C14.2N1, and C17.8N1). The COD/N ratios with a constant concentration of ammonia–nitrogen (NH3–N) were chosen on the basis of the urban domestic wastewater characteristics sampled at the inlet basin of a sewage treatment plant (STP). The parameters of pH, COD, and NH3–N were measured periodically during the experiment. The wild-Serbian GLMPs efficiently removed the pollutants from the synthetic sewage. The COD/N ratio of C17.8N1 wastewater had the best COD and NH3–N removal, as compared to the lower COD/N ratio, and the shortest treatment time was obtained in an acidic environment at pH 4. The highest percentage for COD and NH3–N removal achieved was 96.0% and 93.2%, respectively. The results proved that the mycelium of GLMP has high potential in treating domestic wastewater, particularly at high organic content as a naturally sustainable bioremediation system.

“…The leachate characterization was done for the pH, BOD, COD, ammonia-nitrogen (NH 3 -N), nitrite (NO 2 -), and nitrate (NO 3 -) content in leachate sample based on the Standard Method for the Examination of water and wastewater [22]. All experiments were done in triplicates at 20±2°C to obtain the mean while the determination of all chemical concentrations was measured by using HACH DR 3900 spectrophotometer.…”

The increasing volume of waste disposal and improper management of landfill has been contributing to the heavily polluted leachate. Local freshwater cyanobacteria were identified based on the polyphasic approach that combines morphological and molecular identification by the 16S rRNA gene sequencing method. The local cyanobacteria isolate (A1) was identified as the genus Cyanobacterium of the order Chroococcales. The A1 isolate together with identified cyanobacteria, Anabaena sp. was used to observe their effectiveness in remediating leachate pollution either as monoculture or in mixed culture. Prior to the phycoremediation, the characterization of leachate had been carried out. The biological oxygen demand (BOD5), chemical oxygen demand (COD), pH value, concentration of ammonia-nitrogen (NH3-N), nitrite ( N O 2 − ) , and nitrate ( N O 3 − ) of the raw leachate determined were 22.37 mg/L, 58.33 mg/L, 7.84, 82.7 mg/L, 88.67mg/L and 89.43mg/L, respectively. The use of a single Anabaena sp. demonstrates the most effective in the removal of all contaminants that exist in the leachate. The removal of COD was the highest at 105.71% followed by BOD5 at 92.71% and NO3- at 82.09%. This finding suggested that in order to achieve optimum removal of BOD5, COD, NH3-N, NO2 - and NO3 - content in leachate sample, treatment by Anabaena sp. should be applied.

“…One of these methods, bioremediation, is one of the most effective biotechnologies for removing PTMs. Recently, researchers have found that many microbes that break down waste into smaller forms are also among the most promising technologies due to their efficiency, relative cost-effectiveness, and environmental friendliness (Saetang and Babel 2012;Razarinah et al 2014;Vijayaraghavan and Balasubramanian 2015), and these studies have identified the use of microbial metabolism as an essential part of biotechnology. The mechanism of PTM removal by microorganisms is a rather complex process.…”

Landfill leachate is a serious contaminant for groundwater and surface water because of its potentially toxic metal content. In many countries, leachate is discharged into the natural environment without treatment because of the high disposal cost. However, this environmental problem can be solved by microorganisms, as they can adsorb the contaminants or convert them into end products, and this is cost-effective. This study focused on determining bacteria capable of efficiently removing toxic metals from leachates. Therefore, bacteria were isolated from nature that have a high adsorption and resistance capacity to a number of toxic metals. This potential was achieved by Enterobacter hormaechei, Priestia aryabhattai, and Mycobacterium sacrum, among others. Their efficiency in removing toxic metals compared to raw leachate was Cd (78%, 67%, 78%), Ni (64%, 57%, 56%), Pb (99%, 75%, 76%), Cr (41%, 46%,19%), Co (45%, 60%, 40%), and Cu (80%, 80%, 60%), respectively. According to the results, these bacterial strains proved to be very effective in the treatment of toxic metals from leachate. Therefore, they are good candidates for the treatment of wastewater by bioremedial methods.
