Current status and future prospects of microalgae-based degradation of spent lubricant oil hydrocarbon towards environmental sustainability: a mini review and bibliometric analysis

mycolabadmin

Spent oil waste from cars and industries is a major environmental problem that traditional cleanup methods struggle to handle. This review shows that microalgae, tiny organisms that are already used for various purposes, can effectively break down the harmful chemicals in used oil. A bibliometric analysis reveals that scientists worldwide, especially in China, are increasingly researching this promising green solution to clean up oil pollution in soil and water.

Top-down enrichment of oil-degrading microbial consortia reveals functional streamlining and novel degraders

mycolabadmin

Scientists developed a method to create powerful microbial teams that can break down crude oil more effectively than single microbes. By using enrichment techniques with increasing oil concentrations, they created a streamlined consortium called GT4 that could degrade over 55% of crude oil in one week. The study identified key bacterial players including Microbacterium and discovered new bacteria like Paracandidimonas that can degrade oil, offering promising tools for cleaning up oil-contaminated environments.

Efficacy of Indigenous Bacteria in the Biodegradation of Hydrocarbons Isolated from Agricultural Soils in Huamachuco, Peru

mycolabadmin

Researchers in Peru identified four types of bacteria from agricultural soil that can break down diesel and other hydrocarbon pollutants. One strain, Pseudomonas protegens, was particularly effective, removing over 91% of hydrocarbons in 10 days. This discovery offers a natural, cost-effective way to clean contaminated soil without using harsh chemicals, which could help protect both human health and the environment.

Ecological indicators and biological resources for hydrocarbon rhizoremediation in a protected area

mycolabadmin

A gasoline pipeline spill contaminated a protected nature area in Italy, threatening rare fish species. Scientists tested whether plants and natural bacteria could clean up the pollution. They found that corn and sunflower plants, combined with bacteria from the soil, could remove about 70-80% of the petroleum pollution in just 38 days. The study showed this approach could successfully restore the protected area without expensive chemical treatments.
