This research investigates the corrosion inhibition potential of banana pseudo-stem extract on mild steel in acidic environments. Utilizing gravimetric analysis, the study evaluates inhibition efficiency over time and with varying inhibitor concentrations. Results indicate a maximum inhibition efficiency of 97% after 24 hours with 5% v/v inhibitor concentration and 0.5 M HCl. Phytochemical analysis reveals the presence of proteins, steroids, carbohydrates, flavonoids, tannins, saponins, and glycosides in the extract, supporting its role as a green corrosion inhibitor. Adsorption of inhibitor molecules aligns with Langmuir and Freundlich adsorption isotherm models, confirmed by Gibb’s free energy values. Optimization through Response Surface Methodology predicts optimal conditions for maximum weight loss. Additionally, the study examines inhibition capacity in 0.5 M and 1.0 M HCl solutions, highlighting the extract’s efficiency in reducing corrosion rates. This research contributes valuable insights into the inhibition characteristics of banana pseudo-stem extract under specific conditions, suggesting its potential as an effective corrosion inhibitor for mild steel.

The application of bioactive components in modern industries has increased dramatically. Consumers’ rising awareness of health and well-being has induced industries such as food, nutraceuticals, cosmetics, and pharmaceuticals to develop products containing bioactive ingredients. The increased demand led to researching other sources for extracting and incorporating the bioactive substances. Ultrasonic enzymatic extraction has developed a highly effective approach for extracting bioactive compounds from plant sources. This novel methodology combines the advantages of ultrasonic waves with the specificity and selectivity of enzymes, providing a promising alternative to existing extraction methods. Although efficient in producing better yields, ultrasonic extraction has met certain limitations, which cause heat generation and high energy consumption. The ultrasonic process can generate heat, potentially leading to the degradation of heat-sensitive compounds during extraction. This review focuses on the properties of ultrasonic enzymatic extraction on bioactive compounds, including the effect of enzymes on ultrasonic extraction and its potential in industries. This study briefly describes the development of this integration method and the application of ultrasonic-assisted enzymatic extraction across sectors in various fields. In the future, more recognition should be given to ultrasonic-assisted enzymatic extraction to enhance production efficiency.

This study investigates the presence and distribution of petroleum hydrocarbon carcinogens in the organs of commercially available fish species collected from the Escravos River in Delta State, Nigeria. The Escravos River is known to be heavily impacted by crude oil pollution due to oil exploration and production activities in the region. The bioaccumulation of petroleum hydrocarbons, including polycyclic aromatic hydrocarbons (PAHs), in fish tissues poses potential risks to both aquatic organisms and human consumers. Samples of various commercially important fish species were collected from different locations along the Escravos River and analyzed for the presence of petroleum hydrocarbon carcinogens using gas chromatography-mass spectrometry (GC FID 5890 SERIES II) techniques. Preliminary findings indicate elevated levels of petroleum hydrocarbon carcinogens, particularly PAHs, in the organs of fish sampled from the polluted areas of the Escravos River. Liver and adipose tissues exhibited higher concentrations of PAHs compared to muscle tissue, suggesting organ-specific bioaccumulation patterns. The presence of these carcinogens in commercially available fish species highlights potential health risks to consumers, particularly those reliant on fish as a dietary staple. This study underscores the urgent need for comprehensive environmental monitoring and management strategies to mitigate the impact of crude oil pollution on aquatic ecosystems and human health in the Escravos River region. Further research is warranted to assess the long-term effects of petroleum contamination on fish populations and human communities’ dependent on aquatic resources in the study area.
