“…No information is available in the literature about degradation of diuron by Enterobacter although species from this genus have been extensively studied for degradation of xenobiotic compounds such as acrylamide and polyacrylamide ( Buranasilp and Charoempanich, 2011 ), PAHs ( Festa et al, 2013 ), PCBs ( Adebusoye et al, 2008 ), aliphatic hydrocarbon ( Hua et al, 2010 ), trichlorobenzene ( Adebusoye et al, 2007 ), and the herbicide glyphosate ( Kryuchkova et al, 2014 ). Similarly, P. aeruginosa is the most studied bacterium able to degrade aliphatic and aromatic hydrocarbons ( Al-Saleh and Akbar, 2015 ) besides PAHs ( Zhang et al, 2011 ) and PCBs ( Hatamian-Zarmi et al, 2009 ) but there are no reports about the degradation of diuron. Finally, no reported in biodegradation studies was found involving Leucobacter genera.…”

The isolation of microorganisms from soil impacted by xenobiotic chemicals and exposing them in the laboratory to the contaminant can provide important information about their response to the contaminants. The purpose of this study was to isolate bacteria from soil with historical application of herbicides and to evaluate their potential to degrade diuron. The isolation media contained either glucose or diuron as carbon source. A total of 400 bacteria were isolated, with 68% being Gram-positive and 32% Gram-negative. Most isolates showed potential to degrade between 10 and 30% diuron after five days of cultivation; however Stenotrophomonas acidophila TD4.7 and Bacillus cereus TD4.31 were able to degrade 87% and 68%, respectively. The degradation of diuron resulted in the formation of the metabolites DCPMU, DCPU, DCA, 3,4-CAC, 4-CA, 4-CAC and aniline. Based on these results it was proposed that Pseudomonas aeruginosa TD2.3, Stenotrophomonas acidaminiphila TD4.7, B. cereus TD4.31 and Alcaligenes faecalis TG 4.48, act on 3,4-DCA and 4-CA by alkylation and dealkylation while Micrococcus luteus and Achromobacter sp follow dehalogenation directly to aniline. Growth on aniline as sole carbon source demonstrates the capacity of strains to open the aromatic ring. In conclusion, the results show that the role of microorganisms in the degradation of xenobiotics in the environment depends on their own metabolism and also on their synergistic interactions.

“…Pseudomonas spp. are ubiquitous (Wu et al, 2015) and have been isolated from many environmental samples such as soil (AL-Saleh & Akbar, 2015) and water (Nasreen et al, 2015). Pseudomonas aeruginosa is a common soil bacterium (Gupta et al, 1999) that has been studied extensively and was reported to have biocontrol properties.…”

Bananas are one of the world’s most consumed fruits. Developing countries in the Global South depend on bananas for food security and livelihoods. Still, the banana industry also drives a multinational trade worth billions of US dollars. In addition, banana plants also hold cultural and religious significances in many Asian countries. However, banana production faces several challenges, and one of the major issues is the Fusarium wilt disease caused by the fungus Fusarium oxysporum f. sp. cubense Tropical Race 4 (Foc TR4). This disease threatens numerous banana cultivars, including the Cavendish, the most traded banana cultivar. Therefore, the objective of this study was to find effective measures to control the spread of this disease through antagonistic soil bacteria. This study isolated 14 fluorescent, siderophore-producing bacteria with in vitro inhibition rates of 21.73-50.38% against Foc TR4 from the soil surrounding banana plants. Most of the isolates were identified as Pseudomonas spp. via 16S rRNA sequencing, and phylogenetic analysis based on 16s rRNA sequences showed clustering of isolates congruent with the results of similarity searches. Three isolates that exhibited relatively higher antagonistic activity against Fusarium oxysporum f. sp. cubense compared to other isolates were JBAA132 (50.38%), K2B131 (46.28%), and KTP231 (45.38%). Isolate JBAA132 displayed differences in biochemical characteristics compared to its closest match (Pseudomonas aeruginosa type strain DSM50071). It also demonstrated nitrogen-fixing and phosphate solubilising properties common to plant growth promoters. Therefore, isolate JBAA132 may be further explored as a potential biocontrol agent in curbing the spread of Foc TR4.

This review provides a general overview of petroleum characteristics and bioremediation strategies applications in oceanic environments contaminated with petroleum hydrocarbons during exploration and transportation processes offshore. The vast oil reserves in the offshore fields have been explored for the production of light and heavy oil. The hydrocarbons exhibit very different physicochemical characteristics including those of hydrophobicity, molecular weight, melting and boiling points, toxicity and recalcitrance. This review is to highlight the basic oil characteristics, and to reveal the manner in which accidents can occur resulting in oil spills in the sea. We focus on hydrocarbon degradation through the application of bioremediation techniques, because this is considered more advantageous economically compared with the physical or chemical remediation techniques, as well as being more effective in contaminant removal. This study provides knowledge about strategies that can be applied in accidents involving oil spill on the ocean and thus boosts oil spill cleanup technology and lowers the environmental risks of offshore management of activities with petroleum.
