In vitro antagonistic activity evaluation of some selected fungi isolated from burned soils in Mila region (East of Algeria)

The present study was initiated to (i) determine burned forest-inhabiting fungi in Zouagha, TerriBeinène, Mila and (ii) study the antagonistic activities of Trichoderma sp against Fusarium sp, Penicillium sp, Rhizoctonia sp, and Alternaria sp. Eighteen fungal strains representing six genera were isolated from soil samples obtained from the burned forest of Zouagha in the Mila region: Trichoderma sp, Fusarium sp,...

Inhibition of biofilms on urinary catheters using immobilized Lactobacillus cells

Bacterial biofilms forming on indwelling urinary catheters continue to represent a public health problem because they are associated with urinary tract infections (UTIs). This study was undertaken to evaluate the ability of immobilized Lactobacillus acidophilus cells to inhibit biofilm formation on catheter surfaces. Urine bacteria and Lactobacillus species were isolated from urine and vaginal swabs (HVS), respectively....

Characterization and purification of bacteriocin produced by Enterococcus sp. GHB26 isolated from Algerian paste of dates "Ghars"

Strain Enterococcus sp. GHB26, isolated from the Algerian paste of dates "Ghars", produced a bacteriocin. This bacteriocin was inactivated by proteolytic enzymes. Antibacterial activity of the bacteriocin was heat stable at 120°C for 20 min (533 AU/ml), stable at pH range of 2 to 12 and resistant to chemicals (SDS, EDTA, NaCl, Tween 80, Urea). The active bacteriocin from the cell-free supernatant of...

β-Fructofuranosidase production by Aspergillus versicolor isolated from Atlantic forest and grown on apple pomace

This study explores the production and characterization of an extracellular β-fructofuranosidase (FFase-I) by Aspergillus versicolor newly isolated from Atlantic Forest-Brazil. The β-fructofuranosidase production by fungus, after the optimization process using central composite design and response surface methodology, showed that 3% (w/v) apple pomace, an initial pH 7.5, and 12 days of cultivation provided the...

Molecular characterization of midgut bacteria of Aedes albopictus exhibiting swarming motility property

Aedes mosquitoes are responsible for the transmission of arboviruses including dengue, chikungunya, zika, and yellow fever throughout the world. Mosquito gut harbors a variety of microbes, known to play a potential role in various physiological processes such as food digestion and pathogen development. Many bacterial species exert various movements like swarming, gliding and twitching which vary with individual...
