“…It is possible to propose that filamentous fungi can degrade organic matrix of the paint, composed of vinyl or acrylic resin or silicone polymers, which in turn can affect release of the biocide and the life span of the antifouling paint. It has been shown that filamentous fungi can deteriorate synthetic paints [57,58]. Additionally, filamentous fungi can degrade biocides of antifouling paints, such as Irgarol 1051 [59] and TBT [60].…”

“…Alternaria spp. have been isolated from terrestrial contaminated zones with evidence of PAH degradation [57], from tar balls with a very limited ability to degrade crude oil [49], and from noncontaminated gardens showing the ability to degrade octane and decane [58]. A. alternata has the capacity to synthesize enzymes related to hydrocarbon degradation, such as manganese peroxidase and lignin peroxidase [59,60].…”

Extra-Heavy Crude Oil Degradation by Alternaria sp. Isolated from Deep-Sea Sediments of the Gulf of Mexico

et al. 2021

The Gulf of Mexico (GoM) is an important source of oil for the United States and Mexico. There has been growing interest, particularly after the Deepwater Horizon oil spill, in characterizing the fungal diversity of the GoM and identifying isolates for use in the bioremediation of petroleum in the event of another spill. Most studies have focused on light crude oil bioremediation processes, while heavy crude oil (HCO) and extra-heavy crude oil (EHCO) have been largely ignored. In this work, we evaluated the ability of fungal isolates obtained from deep-sea sediments of the Mexican economic exclusive zone (EEZ) of the GoM to degrade HCO (16–20° API) and EHCO (7–10° API). Alternaria sp., Penicillium spp., and Stemphylium sp. grew with HCO as the sole carbon source. Remarkably, Alternaria sp. was the only isolate able to grow with EHCO as the sole carbon source, degrading up to 25.6% of the total EHCO and 91.3% of the aromatic fraction, as demonstrated by gas chromatography analysis of the saturate, aromatic, and polar fractions. These findings proved to be significant, identifying Alternaria sp. as one of the few fungi reported so far capable of degrading untreated EHCO and as a suitable candidate for bioremediation of EHCO in future studies.

“…It seems incorrect to assume that all processes will simply add to a more rapid disappearance of the chemical and its degradation products from the environment. Data of Loretta et al (2017) illustrate that biodegradation of a chemical may reduce the effect of volatilisation from the soil. Another example is the assumption that volatile lower halogenated organic compounds rapidly evaporate from river water while these compounds persist for many years after infiltration of the water via the river banks into the ground.…”

In Syria, there are no effective chemicals management programmes including any estimation and assessment programmes to screen organic chemicals for bioaccumulation potential from regulatory and resource implications are conducted yet. An important issue of excessive organic hazardous substances exposure of inhabitants living in Barada basin (Southwest) was not investigated. Among these danger substances, Persistent Organic Pollutants (POPs) have specific properties make them possible linger in soil and water for so many years. Considering the Toxic Substances Control Act (TSCA) and enabling activities for the Stockholm convention on POPs related to the national implementation plan for Syria, the current paper presents the results of the analysis of the persistence of chemicals in surface water and ground water samples gathered from different locations in this basin. The study was conducted in 2007-2008, the biodegradability under laboratory and filed conditions were assessed, half?lives of priority pollutants were predicted, and data were monitored and compared. The level of POPs in a larger percentage of the samples exceeded guidelines which results a call for additional protective measures for a sustainable water management for producing clean water involving reduction strategies to mitigate the POPs concentrations in the indoor environment of Barada, and safely destroy them.
