...robial contamination and biofilm formation in food industries pose a threat to human health worldwide. With the increased use of antibiotics in food industry, the problem of bacterial resistance is emerging, hence leading to serious health issues. Among 24 strains isolated from Shaukat Banaspati Ghee industry (Grw) and Shezan foods (pvt) Ltd, Lahore, Pakistan food industry, 10 highly antibiotic resistant strains were subjected to morphological, physiological a...

...obicity, aggregation and biofilm formation of two salt tolerant strains [Bacillus subtilis and Halomonas aquamarina (1)] in the presence of nickel. Two concentrations of nickel were used i.e., 500μg/ml and 1000μg/ml for subsequent tests. The results revealed that at low/ sub-inhibitory concentration of nickel (500 μg/ml), motility is inhibited; adhesion, hydrophobicity, aggregation, EPS production and biofilm formation<...

...nhibited and delayed the biofilm formation by S. mutans and a profound effect was observed in case of the extracts of Streptomyces strains HU-09 and HU-10, which delayed biofilm maturation and even decreased biofilm formation with the passage of time. The micro well cytotoxicity assay against Artemia salina showed the cytotoxicity of the extracts in the range of 10-35%. The chemical profiling of the extr...

...ed significantly reduced biofilm formation (52%; p<0.05) by test tube method compared to liquid interface coverslip assay (35%) and congo red assay. D. vulgaris was treated with various concentrations (5, 40, 80 and 100µM) of salicylidene acylhydrazide and 5-15 µM of proteases (proteinase K, trypsin, and chymotrypsin). Concentration dependent decrease was observed after 72 hours in biofilm formation of ...

...sent study aims to check biofilm formation and auto aggregation potential of the bacteria associated with cockroaches. For this purpose, cockroaches were captured from house sewerage and two bacterial strains CXA1 (Planomicrobium chinense) and IM2 (Alkaligenes faecalis) were isolated from external surface and rectum portion of cockroach, respectively. Bacterial autoaggregation started increasing after 1 h of culture incubation and reached maximum...

Gallinarum strains isolated from commercial broiler chicken by three different methods i.e., congo red, test tube and air liquid interface coverslip, (2) biofilm quantification at different time intervals and (3) monitor antibiofilm effect of three proteolytic enzymes including trypsin, chymotr...
