“…For instance, microorganisms capable of degrading other classes of endocrine disruptors have been already selected and tested using the same methodology 70 . Moreover, other marine and terrestrial organisms, such as sponges and plants 71,72 , as well as distinct types of environmental samples, such as soil, fuel, and rocks can be used as the degrading-microbial sources 25,73,74 . For instance, it was possible to detect and isolate hydrocarbon-degrading bacteria from different soil and sediment samples 25,54,63,64,75 .…”

Pollution affects all biomes. Marine environments have been particularly impacted, especially coral reefs, one of the most sensitive ecosystems on Earth. Globally, 4.5 billion people are economically dependent on the sea, where most of their livelihood is provided by coral reefs. Corals are of great importance and therefore their extinction leads to catastrophic consequences. There are several possible solutions to remediate marine pollutants and local contamination, including bioremediation. Bioremediation is the capacity of organisms to degrade contaminants. The approach presents several advantages, such as sustainability, relatively low cost, and the fact that it can be applied in different ecosystems, causing minimal impacts to the environment. As an extra advantage, the manipulation of endogenous microbiomes, including putative beneficial microorganisms for corals (pBMCs), may have probiotic effects for marine animals. In this context, the use of the two approaches, bioremediation and pBMC inoculation combined, could be promising. This strategy would promote the degradation of specific pollutants that can be harmful to corals and other metaorganisms while also increasing host resistance and resilience to deal with pollution and other threats. This method focuses on the selection of pBMCs to degrade two contaminants: the synthetic estrogen 17a-ethinylestradiol (EE2) and crude oil. Both have been reported to negatively impact marine animals, including corals, and humans. The protocol describes how to isolate and test bacteria capable of degrading the specific contaminants, followed by a description of how to detect some putative beneficial characteristics of these associated microbes to their coral host. The methodologies described here are relatively cheap, easy to perform, and highly adaptable. Almost any kind of soluble target compound can be used instead of EE2 and oil.

For instance, 4.5 billion people depend on ocean fish as their main food source 16 , which are greatly supported by coral reefs. Regardless of their ecological, social, and economic importance, coral reefs are being decimated 17,18. Anthropogenic activities are primarily responsible for contributing to the three main causes of corals' death: climate change, overfishing, and water pollution 19. Even though it is important to work on the mitigation of global warming, it is also important to work on minimizing local contamination, including water pollution,

“…aculeata pulp oil and J. curcas oil as candidates for biodiesel production have been well explored by the previous studies (Raspe et al, 2014; Souza et al, 2016), but little has been reported on how their stability under storage condition is affected by microbial growth. It should be mentioned that some other biodiesel feedstocks such as soybean oil, olive oil, linseed oil, and beef tallow have been investigated in terms of their susceptibility to microbial contamination during storage (Cazarolli et al, 2012;Cazarolli et al, 2014;Soriano et al, 2015). However, based on their physicochemical properties, the biodiesel produced may have different characteristics which can directly influence the degradation reactions of abiotic or biotic nature during storage (Ramos et al, 2009).…”

“…However, biodiesel blends are highly susceptible to microbial contamination due to their hygroscopic capacity and its structure, predominantly composed by eight different methyl esterified fatty acids [5,6,7,8]. As a result, the contamination negatively affects product quality, compromises system and engine performance, as well as contributes to the corrosion of storage tanks [9].…”

Biocides Used as Additives to Biodiesels and Their Risks to the Environment and Public Health: A Review

One of the advantages of using biodiesel and its blends with diesel oil is the lower levels of emissions of particulate matter, sulfur dioxide, carbon monoxide, among others, making it less harmful to the environment and to humans. However, this biofuel is susceptible to microbial contamination and biodeterioration. In this sense, studies on the use of effective low toxicity biocides are being carried out, and this work aims to present the latest information (2008–2018) available in the scientific databases, on the use of biocides in biodiesel, mainly concerning their toxicity to the environment and public health. The results showed that in relation to the control of microbial contamination, the current scenario is limited, with seven publications, in which the most studied additives were isothiazolinones, oxazolidines, thiocyanates, morpholines, oxaborinanes, thiocarbamates and phenolic antioxidants. Studies regarding direct experiments with humans have not been found, showing the need for more studies in this area, since the potential growth of biodiesel production and consumption in the world is evident. Thus, there are need for more studies on antimicrobial products for use in biodiesel, with good broad-spectrum activity (bactericidal and fungicidal), and further toxicological tests to ensure no or little impact on the environment.
