“…The presence of these species in polluted environments is due to their ability to tolerate and use pollutants as a source of carbon and energy [27]. Most of these strains have already been identified in environments polluted by hydrocarbons [10,[27][28][29]. Liang et al (2014) also identified a strain of Pseudomonas sp.…”

The oil palm industry contributes significantly to the economic development of producing countries such as Cameroon. Unfortunately, the exploitation of palm oil constitutes a source of environmental pollution due to the production of enormous quantities of waste during its extraction process, including solid sludge generating greenhouse gases which contribute to global warming climatic. All this leads to the search for alternatives which consists of isolating and characterizing indigenous bacteria with biodegradation capacities in sludge from palm oil extraction. The pH and bacterial counts were determined by the potentiometric method and the decimal dilution technique, respectively. The isolated bacteria were identified by their cultural, cellular and biochemical characteristics. In addition, the identification of Gram- bacteria was further explored by the API 20 E gallery. The palm oil biodegradability test was carried out on M2 medium supplemented with 2% palm oil. The solid sludge biodegradability test was carried out on liquid MSM medium supplemented with 4% sludge stock solution. The results showed that the sludge sample had a slightly alkaline pH of 7.3. A bacterial load of around 109 CFU/g of soil was counted. Thirty-one bacterial strains were isolated and purified, including 12 Bacillus sp, 10 Pseudomonas sp, 8 Proteus mirabilis and 1 Klebsiella pneumoniae. All isolates tested for their ability to degrade palm oil or solid sludge grew in culture media with palm oil or solid sludge as the sole source of carbon and energy but with a difference in load. Thus, isolates BI2, BI5, BI31, BI10 and BI 9 showed the highest degradation capacities. These isolates could be used to constitute consortia of microorganisms that can be used in the treatment of waste generated by palm oil extraction.

“…However, these physicochemical methods are acquainted with problems such as incomplete decomposition or breakdown of contaminants, and moreover, the technologies are comparatively expensive when compared to biodegradation (Das andChandra, 2011Benchiuk andChibani, 2017). Although, freely suspended cells used in biodegradation have limited capacity, recently the new trend which has gained more attention is cell immobilization on solid support or adsorbent (Sreenivasulu, 2012), and many of these technologies have been used successfully for crude oil bioremediation.…”

This study investigated snail shell as a carrier to immobilize Pseudomonas putida and Bacillus subtilis isolated from refinery effluent for the degradation of naphthalene in synthetic wastewater at various process conditions such as initial naphthalene concentration, pH, adsorbent dosage and ambient temperature of 30 o C in batch mode. The results showed that the adsorption and the biodegradation capacity increased with increase in naphthalene concentration, where 73.11%, 74.46% and 65.20% of the optimum concentration (50 mg/L) were removed by immobilized Pseudomonas putida, Bacillus subtilis, and snail shell respectively after 72 hours incubation. The optimal degradation occurred at the adsorbent dosage of 2 g at pH 9 and pH 7 for the adsorption and biodegradation respectively. The results were well fitted to both Langmuir and Freundlich models. Therefore, snail shell can be employed as a low-cost adsorbent and solid support matrix for immobilizing microorganisms in remediating hydrocarbon contaminants.
