“…On the other hand, there are several Candida species with non-pathogenic features and their ability to form biofilm are studied in bioremediation processes [15]. For instance, Candida viswanathii TH1 isolated from oil-polluted sediments collected in coastal zones in Vietnam can transform branched aromatic hydrocarbons in biofilm than in planktonic form [16]. In addition, Candida maltosa biofilm was used to degrade and remove phenol with efficiency 7 times more efficiently than without biofilm [17].…”

These adhesins are encoding by ALS3, HWP1 and EAP1 genes among others and they are also considered as Candida virulence factors.Methodologies use to study biofilm productions are intended to verify the biofilm composition, formation steps, tridimensional structure and might facilitate the monitoring of biofilm regarding, antibiotic resistance, degradations, inhibitors, enhanciement biofilm formation and other features.Here, FISH expression a modified method to detect gene expression in situ was used in order to detect ALS3, HWP1 and EAP1 in C. albicans and C. maltosa biofilms, constituting a useful tool to monitor biofilm formations. In this regard, ALS3 expression was identified in C. albicans and C. maltosa biofilms.

28"Oil-polluted sediment bioremediation depends on both physicochemical and 29" biological parameters, but the effect of the latter cannot be evaluated without the optimization 30" of the former. We aimed in optimizing the physicochemical parameters related to 31" biodegradation by applying an ex-situ landfarming set-up combined with biostimulation to 32" oil-polluted sediment, in order to determine the added effect of bioaugmentation by four 33" allochthonous oil-degrading bacterial consortia in relation to the degradation efficiency of the 34" indigenous community. We monitored hydrocarbon degradation, sediment ecotoxicity and 35"hydrolytic activity, bacterial population sizes and bacterial community dynamics, 36"characterizing the dominant taxa through time and at each treatment. We observed no 37" significant differences in total degradation, but increased ecotoxicity between the different 38" treatments receiving both biostimulation and bioaugmentation and the biostimulated-only 39" control. Moreover, the added allochthonous bacteria quickly perished and were rarely 40" detected, their addition inducing minimal shifts in community structure although it altered the 41" distribution of the residual hydrocarbons in two treatments. Therefore, we concluded that 42" biodegradation was mostly performed by the autochthonous populations while 43" bioaugmentation, in contrast to biostimulation, did not enhance the remediation process. Our 44" results indicate that when environmental conditions are optimized, the indigenous 45" microbiome at a polluted site will likely outperform any allochthonous consortium. 46"47"
