Bacterial spoilage of food products is regulated by density dependent communication system called quorum sensing (QS). QS control biofilm formation in numerous food pathogens and Biofilms formed on food surfaces act as carriers of bacterial contamination leading to spoilage of food and health hazards. Agents inhibiting or interfering with bacterial QS and biofilm are gaining importance as a nov...
Electricity generation by Geobacter sulfurreducens biofilms grown on electrodes involves matrix-associated electron carriers, such as c-type cytochromes. Yet, the contribution of the biofilm's conductive pili remains uncertain, largely because pili-defective mutants also have cytochrome defects. Here we report that a pili-deficient mutant carrying an inactivating mutation in the pilus assembly ...
Background: Oral biofilm studies based on simplified experimental setups are difficult to interpret. Models are limited mostly by the number of bacterial species observed and the insufficiency of artificial media. Few studies have attempted to overcome these limitations and to cultivate native oral biofilm. Aims: This study aimed to grow oral biofilm in vivo before transfer to a biofilm reactor...
OBJECTIVES Epidemic methicillin-resistant S. aureus (MRSA) clones cause infections in both hospital and community settings. As a biofilm phenotype further facilitates evasion of the host immune system and antibiotics, we compared the biofilm-forming capacities of various MRSA clones. METHODS Seventy-six MRSA classified into 13 clones (USA300, EMRSA-15, Hungarian/Brazilian etc.), and isolated ...
Microorganisms have developed a resistance against some of the most conventional antibiotics. These microorganisms can be self-assembled, forming microbial biofilm. A biofilm formation is an inherent event on almost any surface, causing countless side effects human health and environment. Therefore, multiple scientific proposals been based renewable sources such as natural polymers. Natural pol...
To augment the removal of pharmaceuticals different conventional and alternative wastewater treatment processes and their combinations were investigated. We tested the efficiency of (1) two distinct laboratory scale biological processes: suspended activated sludge and attached-growth biomass, (2) a combined hydrodynamic cavitation-hydrogen peroxide process and (3) UV treatment. Five pharmaceuti...
Candida albicans is an opportunistic fungal pathogen that highly resistant to contemporary antifungals, due their biofilm lifestyle. The ability of C. invade human tissues its filamentation. Therefore, inhibition biofilms and filamentation the yeast are high value targets develop next-generation antifungals. Curcumin (CU) a natural polyphenol with excellent pharmacological attributes, but limit...
Moving bed biofilm reactor (MBBR) is considered as a promising technology for wastewater treatment owing to the high biomass retention and low cost. In this study, performance of using MBBR partial denitrification (PD) was investigated. Denitrifying successfully formed after 40 days with nitrite reduction rate 40.83 mg VSS/g carriers 51.52 N/(gVSS·h), respectively. Morphology analysis by scanni...
