Summary: Neochloris minuta and Neochloris alveolaris grown in nitrogen-rich and nitrogen-depleted media were tested for their maximum biosorption capacities and adsorption efficiencies for heavy metals. Removal of nitrogen resulted in increased lipid content, decreased protein content, and enhanced metal adsorption capacities. N. alveolaris showed the highest adsorption capacities for all five metals, with the highest adsorption efficiency percentages ranging from 50.61% to 87.10%.

Summary: Arabica-coffee and Theobroma-cocoa agroindustrial wastes were treated with NaOH to efficiently remove Pb(II) from aqueous media. The biosorbents exhibited significantly higher Pb(II) adsorption capacities compared to untreated wastes and other similar agro-industrial biosorbents. The optimal conditions for Pb(II) adsorption were found to be a pH between 4 and 5 with a biosorbent dose of 2 g center dot L-1. The adsorption process was found to be chemisorption with a monolayer mechanism.

Summary: Heavy metal pollution is a critical global issue, and bioremediation is considered a promising approach. This study investigated the biosorption characteristics of Cd(II), Pb(II), Cu(II), and Zn(II) from aqueous solutions using three phosphorus-accumulating organisms (PAOs) biomasses. The results showed that the biosorption capacity of the biosorbents to heavy metal ions was affected by the solution pH and increased with higher pH values. The experimental data of biosorption were well fitted with the Pseudo-second-order, Redlich-Peterson, and Temkin models, suggesting a hybrid chemical reaction-biosorption process.

Summary: Heavy metals cause serious pollution, but microalgae can effectively treat them. Biomass as a substitute for petroleum is gaining importance. In this study, Chlorella vulgaris was used as an adsorbent to treat heavy metal pollution and the waste was then converted into platform compounds. The results demonstrate the potential of using metal-containing microalgae biomass to produce platform compounds.

Summary: Tannery effluent, with high levels of chromium and other pollutants, can cause serious environmental pollution and pose risks to aquatic life, wildlife, and human health. Conventional physicochemical methods for chromium removal have limitations, while biological methods using microalgae show promise as sustainable, environmentally friendly, and cost-effective solutions. Microalgae species such as Chlorella vulgaris and Scenedesmus sp. have been successful in removing chromium from tannery wastewater and improving its quality for discharge.

Summary: Untreated Pinus radiata sawdust was found to be a promising and efficient adsorbent for the removal of Cu+2 ions from aqueous solutions. The best conditions for adsorption efficacy (93.4% removal percentage and 0.82 mg/g adsorption capacity) were achieved by increasing the adsorbent dose to 5 g/L, adjusting the solution pH to 7, and decreasing the initial metal ion concentration to 5 mg/L. The adsorption process involved different stages and fitted well with the Langmuir isotherm and second-order kinetic model. Additionally, high desorption efficiencies up to 94.5% were achieved, and the possibility of sawdust regeneration was studied.

Summary: The study investigated the potential of ACSB as a biosorbent for removing heavy metals such as Cr(VI), Cd(II), Zn(II), Cu(II) and Pb(II), finding that ACSB is more effective in removing Pb(II), Cu(II), and Cd(II). By optimizing parameters such as pH, time, dosage, and initial metal concentration, the study identified the conditions under which maximum removal efficiency could be achieved. The results also showed that ACSB followed a pseudo 2nd order sorption kinetics for the removal of metal ions.

Summary: This study investigated the use of Scenedesmus sp. as an adsorbent to remove lead and cadmium from a metal solution. The effects of various factors on the adsorption process were examined, and the ideal conditions for each metal were determined. The biosorption process was quick, with high removal percentages. The biosorption capacities and desorption rates were determined, and the functional groups and morphological changes on the adsorbent surface were analyzed. Scenedesmus sp. showed great potential as an alternative sorbent for heavy-metal-contaminated wastewater treatment.

Summary: The purpose of this study was to determine the antifungal and antibiofilm activity of Lemongrass oil against C. parapsilosis and C. tropicalis. The major compounds in Lemongrass oil were analyzed and the oil was found to have significant antifungal activity against both Candida species. Furthermore, Lemongrass oil inhibited biofilm formation on polystyrene and polyvinyl plastic surfaces. The findings suggest that Lemongrass oil can be used to control biofilm-related infection.
