Summary: Fossil fuel depletion and carbon dioxide emissions require more carbon neutral energies like algal biofuels, but their actual production is limited due to expensive and energy-intensive manufacturing. Adding nanomaterials to algal cultures can help increase algal growth and lipid content, as well as enhance lipid extraction. This review discusses nanotechnologies to improve biofuel production from microalgae, including their use as a source of fuel, food supplements, and CO2 for biorefineries. Nanocatalysts for biodiesel production are compared with enzymatic catalysts, with a focus on metallic, magnetic, metal oxide or acid-functionalised nanoparticles, and carbon nanotubes.

Summary: This study investigated the optimization of thermal-diluted acid pretreatment on native grass biomass for simple sugar recovery, followed by lipid bioproduction using Yarrowia lipolytica. The maximum total reducing sugar (34.26 +/- 1.55 g/L) in the native grass hydrolysate was obtained at 163.8 degrees C, 1.57% (v/v) sulfuric acid concentration for 21 min. Detoxified native grass hydrolysate yielded 11.64 +/- 0.84 g/L of lipid with 65.52% (w/w) lipid content after 96 h using Y. lipolytica. These results highlight the efficiency of optimizing thermal-diluted acid pretreatment on native grass biomass for lipid production using Y. lipolytica.

Summary: This article discusses the methods, techniques, and parameters involved in using biomass to manufacture fuels and chemical compounds. Biofuels derived from biomass, which includes grasses, agricultural waste, animal waste, and other organic materials, have gained significant attention due to their abundant supply and lower greenhouse gas emissions. The conversion process of biomass to fuel is affected by various factors such as pH, temperature, and residence time, as well as the availability of carbon, nutrients, and other chemical agents. The research and development of biomass-to-energy conversion technology is growing rapidly, and the choice of conversion method depends on factors such as biomass type, final energy form, and environmental and economic considerations.

Summary: In this study, L-lysine modified mesoporous silica nanoparticles (MS@Lys NPs) were synthesized for the delivery of the anticancer drug curcumin (Cur) to cancer cells. The functionalization of L-lysine groups onto the mesopore channel surfaces of MS@GPTS NPs was achieved through a ring-opening reaction. The structural properties of MS@Lys NPs were examined using various instrumental techniques. The drug loading and pH-responsive drug delivery behavior of MS@Lys NPs were investigated using curcumin as a model drug, and their cytocompatibility and cell uptake behavior were evaluated using MDA-MB-231 cells. The results suggest that MS@Lys NPs have potential for pH-responsive drug delivery in cancer therapy.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.
