“…Some comparable data, such as morphology, phenotype, and characterization of bacteria should be considered in the search for possible bacteria in PAHs biodegradation (Lloyd et al 2010;Marzuki et al 2016). Several factors explain the difference in the biodegradation activity of bacteria to PAHs, including 1) the properties of PAHs with a higher toxicity level of pyrene than naphthalene have an effect on the biodegradability of bacteria; 2) the characteristics and adaptability of bacteria to predators are different; and 3) the number of bacterial cells, the supply of nutrients and oxygen have contributed to the growth, development activity, and strength of the cells (Medić et al 2020). The amount of bacterial biodegradation activity against PAHs is determined on the basis of the biodegradation parameters.…”

Abstract. Marzuki I, Kamaruddin M, Ahmad R. 2021. Identification of marine sponges-symbiotic bacteria and their application in degrading polycyclic aromatic hydrocarbons. Biodiversitas 22: 1481-1488. Diverse and abundant microbial species that occupy marine sponges may make important contributions to host metabolism. Sponges are filter feeders and devour microorganisms from the seawater around them. Each microbe that endures the sponges’ digestive and immune responses are related symbiotically. Marine sponges symbiont bacteria can comprise as much as 40% of sponge tissue volume, and these are known to exhibit a great potential on polycyclic aromatic hydrocarbons (PAHs) degradation. However, the potential use of marine sponges symbiont bacteria is unexplored. Therefore, we designed and conducted a study to identify bacterial isolates obtained from sponges. For this, we collected sponges samples (Hyrtios erectus, Clathria (Thalysias) reinwardti), Niphates sp., and Callyspongia sp.) from the Spermonde islands in Indonesia. We successfully found eight bacterial isolates from four sponges, as molecular identification based on 16S rRNA approach revealed bacterial isolates of SpAB1, SpAB2, SpBB1, SpDB1, and SpDB2 from three sponges (Hyrtios erectus, Clathria (Thalysias) reinwardti), Niphates sp.). Interestingly, these were closely related to Pseudomonas, and a bacterial isolate from Callyspongia sp. (SpCB1) showed similarity to Bacillus. Bacillus and Pseudomonas bacteria isolated from hydrocarbon-contaminated sponges exhibited degradation of naphthalene and pyrene PAHs.

“…For n-alkanes (C 8 -C 40 ), the aerobic degradation is divided into three oxidation modes [124]. These modes are known as terminal oxidation [125], subterminal oxidation [126], and biterminal oxidation [127]. The oxidation modes take place at different carbon positions and form various end products.…”

Oil pollution can cause tremendous harm and risk to the water ecosystem and organisms due to the relatively recalcitrant hydrocarbon compounds. The current chemical method used to treat the ecosystem polluted with diesel is incompetent and expensive for a large-scale treatment. Thus, bioremediation technique seems urgent and requires more attention to solve the existing environmental problems. Biological agents, including microorganisms, carry out the biodegradation process where organic pollutants are mineralized into water, carbon dioxide, and less toxic compounds. Hydrocarbon-degrading bacteria are ubiquitous in the nature and often exploited for their specialty to bioremediate the oil-polluted area. The capability of these bacteria to utilize hydrocarbon compounds as a carbon source is the main reason behind their species exploitation. Recently, microbial remediation by halophilic bacteria has received many positive feedbacks as an efficient pollutant degrader. These halophilic bacteria are also considered as suitable candidates for bioremediation in hypersaline environments. However, only a few microbial species have been isolated with limited available information on the biodegradation of organic pollutants by halophilic bacteria. The fundamental aspect for successful bioremediation includes selecting appropriate microbes with a high capability of pollutant degradation. Therefore, high salinity bacteria are remarkable microbes for diesel degradation. This paper provides an updated overview of diesel hydrocarbon degradation, the effects of oil spills on the environment and living organisms, and the potential role of high salinity bacteria to decontaminate the organic pollutants in the water environment.

“…The success of bioremediation is largely governed by the survival, adaptability and catabolic activities of the introduced microorganisms. Some of the bacterial strains successfully used for this purpose include Pseudomonas aeruginosa (san ai) (Medic et al 2020), Comamonas testosteroni BR60 (Gentry et al 2001), Pseudomonas putida ZWL73 (Niu et al 2009), Bacillus sp. (Kiamarsi et al 2018) etc.…”

“…The contaminated sites selectively promote growth of hydrocarbon degrading bacterial populations. Two bacterial genera namely Pseudomonas and Bacillus have been extensively reported from hydrocarbon contaminated sites (Das and Mukherjee 2007;Kiamarsi et al 2018;Medic et al 2020). Several studies have demonstrated active involvement of Pseudomonas (Bhattacharya et al 2003;Mulet et al 2011) as the most prominent hydrocarbon degrading bacterial genera.…”

We report kinetics of Assam crude oil degradation by Pseudomonas aeruginosa AKS1 and Bacillus sp. AKS2, both isolated from Assam refinery sediments. The isolates exhibited appreciable degrees of hydrophobicity, emulsification index and biosurfactant production. Crude oil degradation efficiency of isolates was assessed in (1) liquid medium amended with 1% v/v crude oil and (2) microcosm sediments (125 mg crude oil/ 10 g sand). In liquid culture, the biodegradation rate (k) and half-life (t1/2) values were found to be 0.0383 day -1 and 18.09 days for P. aeruginosa AKS1, and 0.0204 day -1 and 33.97 days in case of Bacillus sp. AKS2. In microcosm sand sediments, the estimated biodegradation rate (k) and half-life (t 1/2) values were 0.0138 day -1 and 50 days for P. aeruginosa AKS1, and 0.0113 day -1 and 61.34 days in case of Bacillus sp. AKS2. The level of nutrient treatment in microcosm sand sediment was 125 µg N & 62.5 µg P/g sediment in case of P. aeruginosa AKS1 and 375 µg N & 37.5 µg P/g sediment in case of Bacillus sp. AKS2. In microcosms without inorganic nutrients, biodegradation rate (k) and half-life (t1/2) values were found to be 0.0069 day -1 and 100 days for P. aeruginosa AKS1 and for Bacillus sp. AKS2, the respective values were found to be 0.0046 day -1 and 150.68 days. Our data provides important information for predictive hydrocarbon degradation in liquid medium and contaminated sediments.
