Abstract: The influence of nickel on the growth of KB2 strain was tested for different concentrations of metal in the presence of phenol as the sole carbon and energy source. The inhibition effect of nickel on bacterial growth was confirmed even for...

Abstract: The introduction of nickel oxide nanoparticles into the St. maltophilia KB2 cultures did not inhibit the phenol biodegradation process, and the reactions of the bacterial population were depended on the nanoparticles concentrations and the...

Abstract: Plastics are long chain synthetic polymers produced based on fossil fuels such as oil and natural gas. Due to their properties, like lightness, durability, strength, flexibility, and low production costs, they have become indispensable in everyday...

Summary: Nowadays, plastics are widely used in all aspects of life. This is related to their physicochemical properties, high strength, durability, and low production costs. An alternative to conventional plastic waste management methods is environmentally...

Abstract: The cometabolic biodegradation of 4-chlorophenol by Stenotrophomonas maltophilia KB2 strain in the presence of phenol as the sole carbon and energy source was studied. The experiments were carried out in a batch bioreactor. The tests were conducted...

Abstract: Basic types of airlift reactors are presented and hydrodynamic regimes of their operation are described. Influence of some parameters (gas and liquid velocity, reactor geometry and liquid properties) on gas holdup in airlift reactor is discussed....
