Biosorption and biodegradation of pyrene by Brevibacillus brevis and cellular responses to pyrene treatment

“…Pyrene is less bioavailable and more resistant to biological attacking as a typical high-molecular weight polycyclic aromatic hydrocarbon (PAH) (Dissanayake et al, 2010). With wide distribution in the aquatic environment, pyrene, which is toxic to human and organisms, represents a major portion of the total PAHs found in contaminated sites (Oliveira et al, 2012).…”

Immunotoxic effect of Benzo[α]Pyrene and chrysene in juvenile white shrimp Litopenaeus vannamei

“…Moreover, the haemocyte may participate in damage repair, resulting in a decrease of count in hemolymph [11]. Such a decrease in THC has also been reported in crustaceans as a result of the exposures to PAHs [26], PCBs [32] and ammonia-N [18]. The lysosomes play an important role in the immune defense system of crustaceans, which not only take part in phagocytosis, but also can release various hydrolytic enzymes to the haemolymph to participate in the humoral response [11].…”

“…It is generally considered that the immune mechanisms of crustaceans have two distinct pathways: cellular and humoral defence mechanisms [25]. In crustaceans, the hemocyte plays a central role in mediating immune capability via phagocytosis, encapsulation and nodule formation, while humoral immune factors play a very important role in the immune responses, including all kinds of antibacterial, antiviral, coagulation, cell-activating, and recognition factors, and lectin, hemolysin, lysozyme, hydrolase and other immune active substances [26,27]. Therefore, the THC in hemolymph was usually used as an important parameter to evaluate the immunotoxicity of pollutions [9].…”

The Influence of Diet Composition on Fitness of the Blue Crab, Callinectes sapidus

“…However, most marine invertebrates primarily accumulate toxins by uptake from the surrounding water column [ 75 ]. Many other types of pollutants besides metals, ranging from pesticides to polycyclic aromatic hydrocarbons (PAHs; fossil fuel derivatives), are known to impair the foraging behavior of crabs and fish [ 76 – 78 ], and may indirectly reduce the fitness of exposed species through such dietary changes.…”
