“…Pseudomonas putida is part of the soil microbiota and possesses enzymes called dioxygenases that are involved in hydrocarbon degradation (Truskewycz et al 2019 ). On the other hand, species belonging to the Bacillus genus present high adaptability and can grow in extreme and hostile environments such as hydrocarbon contaminated soil and water (de Mesa et al 2006 ; Valdivia-Anistro et al 2018 ). Furthermore, the Bacillus genus is another bacterium reported as petroleum hydrocarbon degrader, and could be useful in reducing the levels of these hydrocarbons (Kolsal et al 2017 ; Lima et al 2020 ).…”

Hydrocarbon-degrading bacteria in Colombia: systematic review

2022

Petroleum industry activities worldwide have caused pollution and resulted in environmental degradation. Microorganisms with the potential to reduce pollutant levels by degradation processes have been reported, and bacteria are among such organisms. The first study on bacterial degradation in Colombia was published in 1996. The study isolated bacteria belonging to the Pseudomonas genus from hydrocarbon-polluted sediments. Since then, different reports on degrading bacteria have been published. The objective of this systematic review is to identify and analyze all the studies on hydrocarbon-degrading bacteria performed in Colombia. To accomplish this goal, a literature search was conducted. Inclusion and exclusion criteria were applied, and 37 relevant articles were obtained. We found that 2018 was the year with the largest number of publications in Colombia, and most frequently identified bacterial genera were Pseudomonas and Bacillus. Some studies showed that the degradation of hydrocarbons is more efficient when bacterial consortia are used rather than pure cultures. This study provides information about bacteria with the potential to degrade hydrocarbons in Colombia, which in turn will be a source of information for future studies in this field.

“…Bacillus sp. are not the only bacteria to be used in biocontrol, however they are preferred due to their spore forming ability (Kefi et al, 2015), adaptability to various and unstable conditions (Valdivia-Anistro et al, 2018), as well as their safeness for untargeted hosts and human health (Koutsoumanis et al, 2020;Spears et al, 2021). MTC 2.4 and MTC 2.5 proved a broad-spectrum antifungal activity, in vitro, and biocontrol potential against these strawberry phytopathogens.…”

Strawberries are listed among the functional foods. Beside their appreciated taste, they are rich in antioxidant compounds. Due to their sugars, fleshy pulp and thin skin, as well as dwarf habitus, they are exposed to various plant diseases, especially fungi. Botrytis gray mold is the most destroying pathogen, but there are other fungi that can cause losses in the field or after harvest. The aim of this study is to select some bacterial strains that could be easily formulated as biocontrol agents against various molds. These bacteria were isolated from winery semi-composted marc and analyzed through specific microbiologic methods. Based on their in vitro antagonistic activity, two bacterial isolates were selected. These strains revealed up to 84.2% inhibition of Botrytis cinerea growth, and high antifungal activity against various other fungi, such as Fusarium oxysporum, Macrophomina phaseolina and Sclerotinia sclerotiorum. Qualitative enzymatic tests, as well as microscopic analysis of the microbial interactions revealed fungal degradative enzymes produced by the bacterial strains. As the selected strains were determined to be spore producing bacteria, long term preservation is an advantage for their formulation as plant protection inoculants. Moreover, these bacteria revealed no phytotoxic activity against test plants.
