Over the past century, the demand for petroleum products has increased rapidly, leading to higher oil extraction, processing and transportation, which result in numerous oil spills in coastal-marine environments. Among various oil weathering mechanisms, biodegradation by naturally occurring bacterial populations removes a majority of spilled oil, thus the focus on bioremediation has increased significantly. Replacing non-degradable materials synthesised from fossil fuels with, International journal of molecular sciences, In this experimental research, different types of essential oils (EOs) were blended with polyhydroxybutyrate (PHB) to study the influence of these additives on PHB degradation. The results clearly suggest the possibility to directly use the PHA-rich cells deriving from the MMC production process, with no need of extraction and purification procedures, as a sustainable and effective carbon source bringing remarkable advantages from an economic and environmental point of view. conducted by researchers. /Type /XObject Their toxicities may cause deflocculation and inhibition or interferences during the bioprocess treatment. /Resources << << et al. << apart from the appropriate enzymatic potential for an effective pesticide biodegradation, other factors such as (i) suboptimal environmental conditions, (ii) co-metabolism (fortuitous.
