Summary: The study focused on using immobilized Phaffia rhodozyma cells in natural biopolymer to enhance the bioremediation of toxic chromium compounds in aqueous solutions. The immobilized cells were in the form of spheres (PRS) and flat coatings (PRC) using sodium alginate. The results showed that PRC had higher bioremediation properties than PRS, with a 15% higher chromium removal rate. The study also demonstrated that both PRS and PRC can be used multiple times without a decrease in efficiency for removing chromium ions from the environment.

Summary: This review introduces the techniques and mechanisms of bacteria immobilization on biochar, as well as its applications in bioremediation and agriculture. The immobilization characteristics of biochar depend on pyrolysis methods, raw materials, and properties of biochar. Scanning electron microscope and colony forming unit analysis are commonly used to verify the immobilization efficiency. Applying biochar-immobilized bacteria can improve soil quality, plant growth, and crop yield.

Summary: Dyes, synthetic aromatic compounds with various functional groups, are discharged in effluents and pose a significant threat to aquatic life. The dye industry initially relied on natural sources but shifted to artificial manufacturing. Dyes disrupt the natural equilibrium by reducing photosynthetic activity. In China alone, around 900,000 tons of dyes are produced each year for various industries. Untreated dye wastewater leads to eutrophication, water color change, and oxygen depletion, severely impacting aquatic organisms. Extensive research has been conducted on dye decolorization and biodegradation under aerobic and anaerobic conditions. This review discusses the chemistry, toxicity, and microbial degradation/decolorization of dyes, as well as recent studies and techniques for remediation. Overall, the high biodegradation potential of microbes makes them a promising foundation for green chemistry in eliminating toxic dyes from industrial wastewater.

Summary: This paper discusses the rarely mentioned topic of continuous bioreactors for petroleum degradation and the influence of indigenous bacteria living in seawater on their performance. The study designed a bioreactor with immobilized petroleum-degrading bacteria beads and found that the degradation rate remained above 50% for 27 days but decreased over time. Interestingly, the size of the immobilized bacteria beads decreased significantly during the remediation process, which was closely related to the reduced degradation efficiency. Therefore, this research is important for further study and improvement of bioreactors in the practical context of oil-spill accident recovery.

Summary: Lead is a naturally occurring metal found in small quantities in the earth's crust. It is non-biodegradable and can accumulate in the environment, causing neurotoxicity and developmental changes. Bioremediation, using bacteria, algae, and fungi, has been proven effective in reducing lead concentration. This review focuses on the toxicity, fate, and microbial degradation of lead in the environment.

Summary: High multiplication rates of Hedeoma multiflora Benth. were achieved through in vitro propagation without using plant growth regulators (PGRs). The morpho-anatomical and chemical features of the in vitro plants were similar to those of wild specimens. In vitro biomass production in a PGR-free medium is an appropriate technology to reduce the overexploitation of endangered wild populations and avoid health safety issues related to the edible consumption of the species.
