“…Since the middle of the last century, the use of petroleum degradation microorganisms for spilled oil bioremediation has been widely reported [47,68,70].These studies have indicated that different species of petroleum degradation microorganisms are broadly distributed in marine environment. Once other dominant groups of microorganisms are inhibited after oil contamination while these petroleum degradation microorganisms propagate rapidly and become dominant species [9].…”

Due to the toxicity of petroleum compounds, the increasing accidents of marine oil spills/leakages have had a significant impact on our environment. Recently, different remedial techniques for the treatment of marine petroleum pollution have been proposed, such as bioremediation, controlled burning, skimming, and solidifying. (Hedlund and Staley in Int J Syst Evol Microbiol 51: [61][62][63][64][65][66] 2001). This review introduces an important remedial method for marine oil pollution treatment-bioremediation technique-which is considered as a reliable, efficient, cost-effective, and eco-friendly method. First, the necessity of bioremediation for marine oil pollution was discussed. Second, this paper discussed the species of oil-degrading microorganisms, degradation pathways and mechanisms, the degradation rate and reaction model, and the factors affecting the degradation. Last, several suggestions for the further research in the field of marine oil spill bioremediation were proposed.

“…In algae-based technologies, algae can also actively participate in biodegradation of organic contaminants. Algae contain enzymes that metabolite a variety of xenobiotics and the process can be divided into three phases (Torres et al 2008). Phase-I involves oxidation, reduction, or hydrolysis, which transforms lipophilic xenobiotics into more hydrophilic compounds to facilitate their excretion.…”

Pharmaceuticals and personal care products (PPCPs) consist of a variety of compounds extensively used for the treatment of human and animal diseases and for health or cosmetic reasons. PPCPs are considered as emerging environmental contaminants due to their ubiquitous presence in the environment and high environmental risks. In wastewater treatment plants using conventional activated sludge processes, many PPCPs cannot be efficiently removed. Therefore, there is an increasing need for more effective and cost-efficiency ways of removing PPCPs while treating wastewater. Algae-based technologies have recently attracted growing attentions for their potential application in wastewater treatment and hazardous contaminant removal, which are advantages in reducing operation cost while generating valuable products and sequestrating greenhouse gases at the same time. This work reviews the up-to date researches to reveal potential toxic effects of PPCPs on algae and algae-bacteria consortia, identify mechanisms involved in PPCP removal, and assess the fate of PPCPs in algae-based treatment systems. Current researches suggest that algae and algae-bacteria consortia have great potentials in PPCP removal but more works are required before algae-based technologies can be implemented in large scales. Knowledge gaps are identified and further research focuses are proposed in this review.

“…Stimulatory effects might be related to the presence of some compounds in the stormwater. It has been reported that a number of trace metals are used by living organisms to stabilize protein structures, to catalyze enzymatic reactions and to facilitate electron transfer reactions in the photosynthetic and respiratory processes [15,16]. Harmless effects towards Daphnia sp.…”

Effects from log-yard stormwater runoff on the microalgae Scenedesmus subspicatus

The effects posed by stormwater runoff from an industrial log-yard on the microalgae Scenedesmus subspicatus have been investigated. The effects of stormwater runoff sampled during two rain events on the microalgae were determined in different concentrations (% v:v). The test organisms were exposed to the stormwater runoff 96h and the percentage change in growth rates in relation to a control culture were measured at exposure times of 24h, 48h, 72 and 96h. Whereas the runoff from the first rain event posed in most cases growth stimulatory effects, the runoff from the second rain event inhibited algae growth. Differences in runoff physico-chemical characteristics combined with the hydrological factors of each rain event explained these opposite effects. The occurrence of the "first flush" phenomenon was studied and the results confirmed such occurrences in the second rain event. On the basis of normalized inhibitory effects and runoff volume, it was found that 42, 51 and 50% of the inhibitory effects during exposures of 24, 48 and 72h were associated with the initial 4% of the total discharged volume. To conclude it can be stated that since the stormwater runoff of only 2 rain events posed negative effects on the test organisms, the potential environmental threats posed by these waters during the entire hydrological year needs to be better understood in order to propose an adequate management program.
