“…Further studies showed that, addition of charcoal to soil in a ratio of 1:1, has the potential of carbon sequestration, increase soil fertility, soil pH, reduce leaching, improve soil structures, improve water retention, reduce greenhouse gas emission and has the ability to improve soil quality in degraded or nutrient poor soil thus increasing microbial activity and increased soil respiration (Lehmann, 2007;Atkinson et al, 2010;Major et al, 2010;Zhang et al, 2023). These changes could improve bioavailability of nutrients to the plants and even stimulate the release of plantgrowth-promoting hormones.…”

This study investigated the effect of charcoal and spent engine oil on some growth indices of mangrove seedlings Rhizophora racemose G. Mayer grown in garden soil. The aim was to discover means of improving mangrove nursery growth and survival in the Niger Delta area of Nigeria. Rhizophora racemose was planted in garden soil amended with four different treatments: C (Garden soil only), PC (Garden soil + Charcoal), PCSEO (Garden soil + Charcoal + 6% Spent engine oil), and SSEO (Garden soil + 6% Spent engine oil), with three replicates each and randomized complete block design was adopted for the study. The effect of these treatments was monitored biweekly on some growth indices – plant height, leaf area, leaf length, number of leaves and stem girth, except for root length, number of roots, fresh weight, dry weight and chlorophyll content of R. racemosa which were obtained at 18th week after planting. The study revealed that PC treatment had the highest values for plant height, number of leaves, fresh weight, plant girth, root length when compared to other treatments (C, PCSEO and SSEO) while SSEO recorded the least values. Among the treatments, there were significant differences in the plant height, fresh weight and root length of R. racemosa at P = 0.05. The garden soil amended with charcoal improved the performance of R. racemosa than in spent engine oil alone (PC > PCSEO > SSEO). This could be attributed to the presence of heavy metals in spent engine oil. Again, the charcoal amended soil had higher values for growth indices when compared with the control (C) treatment. This suggest that charcoal has the potency of improving garden soil fertility, plant survival and productivity. Therefore, charcoal could be beneficial in environmental conservation, restoration of endangered forest especially the mangroves in the Niger Delta polluted with crude oil. The study recommends that, charcoal should be incorporated in reforestation and afforestation approaches of mangrove forests.

“…(2) The increase in the acidic properties of the media is a manifestation of the work of bacterial cell degradation, which has succeeded in destroying the molecular structure of PAHs, forming several new components, among which are carboxylic compounds, which results in increased media acidity [110,112]. This stage is a vulnerable period for bacteria, which can result in cells not being able to enlarge and divide, and the bacterial cells may even be threatened with mass death [103,134]. (3) The increase in the temperature of the interaction media due to the formation of new compounds resulting from degradation.…”

“…The rate of the bacterial biodegradation of hydrocarbon contaminants varies in the range of 35-97%. Several factors cause this, such as the type of bacteria used; the type of hydrocarbon pollutant (aliphatic or PAHs) [26,50,102,103]; the interaction time; the degradation method; the concentration of hydrocarbon components used as reactants; the number of bacterial cells; the presence or absence of nutrition; oxygen injection (aeration); the scale of experiments carried out and other factors [32,48,104,105]. Variations in the level of bacterial degradation of hydrocarbon components indicate that multiple factors influence bioremediation [58,106].…”

Toxic materials in waste generally contain several components of the global trending pollutant category, especially PAHs and heavy metals. Bioremediation technology for waste management that utilizes microorganisms (bacteria) has not been fully capable of breaking down these toxic materials into simple and environmentally friendly chemical products. This review paper examines the potential application of a consortium of marine sponge symbionts with high performance and efficiency in removing PAHs and heavy metal contaminants. The method was carried out through a review of several related research articles by the author and published by other researchers. The results of the study conclude that the development of global trending pollutant (GTP) bioremediation technology could be carried out to increase the efficiency of remediation. Several types of marine sponge symbiont bacteria, hydrocarbonoclastic (R-1), metalloclastic (R-2), and metallo-hydro-carbonoclastic (R-3), have the potential to be applied to improve waste removal performance. A consortium of crystalline bacterial preparations is required to mobilize into GTP-exposed sites rapidly. Bacterial symbionts of marine sponges can be traced mainly to sea sponges, whose body surface is covered with mucus.

“…There were no significant differences in the concentration of metals between burnt and unburnt soil. This situation is probably caused by the dissolution and distribution of metals by rainfall [27] between the surface and sub-surface soil three months after the burning of the grasses in October. Another reason is because of the harmattan wind, which causes dryness across the site.…”

Wetland soils derive their chemical composition from the sedimentary rock underneath. Among the metals produced are trace and nutrient elements which facilitate plant growth. Bush burning near mangrove forest is a common practice that has not been given much attention despite its negative impact on the environment. We thus hypothesize that the application of fire on wetland soil will negatively impact the soil chemistry. We collected soil samples from burnt and unburnt soilsat different distances from the point of burning to compare the concentration of nutrient elements (Calcium (Ca 2+ ), iron (Fe), Magnesium (Mg), Nitrate ( 3 NO − ), Phosphate ( 3 4
