Characterization and Potential Applications of Heterotrophic Bacteria Inhabit Nickel Rich Soils in Çanakkale, Turkey

Abstract

Microorganisms inhabit extreme environments such as high nickel rich soils are novel in terms of diversity and also valuable source of extracellular hydrolytic enzymes. The present study focused on isolation and characterization of heterotrophic bacteria from Nickel rich soils in Çanakkale, using culture dependent method and assessment of their heavy metal, antibiotic resistance and potential for production of some industrially important enzymes. Total 35 bacterial isolates were characterized morphologically, biochemically and these analysis of strains revealed that these strains were able to grow between 4-50 °C. These isolates also showed high heavy metal and antibiotic resistance and ability to produce one or more extracellular enzymes like amylase, protease, lipase and DNAse. Thus, the isolates from Ezine, Çanakkale could be potential candidates for industrial applications.
