Background: The enzyme arginase plays a significant role in the growth of many organisms as important biological enzyme. Objective: The study was designed to isolate L-arginase from P. aeruginosa that isolated from sewages and to evaluate the influence of arginase on biofilm-generating bacteria. Materials and Methods: The current study includes 28(...

Ten isolates of the genus Serratia marcescens were isolated from 45 samples collected from hospital environments between November 2021 and April 2022 at Ibn-Albalady hospital-Muhammad Baqir al-Hakim hospital, Kadhimiya Teaching Hospital, and the teaching laboratory at Medical City hospital. Since their original detection, these isolates have been i...

Pollution is one the most big and dangerous problems faced by human on the earth, because water considered the source of life, water pollution effects on human, animals and plants. water pollution occurred recently in Basra city-560 km south of Baghdad-that lead to death of many plants and animals like fish in high quantities, most peoples live in...

This study was conducted to explore the ability of Pseudomonas fluorescens and Bacillus cereus to solubilizing a phosphate in soil for enhancing the planting growth and, its relation with soill characterization. The isolates were identified as P.fluorescens and B. cereus using convential analysis and, its phosphate solubilization ability and sidrop...

The development response of the biocontrol agent Pantoea agglomerans to changes in temperatures was identified in vitro in nutrient, yeast extract–sucrose, medium. The least temperature of which P. agglomerans could develop was 4°C and the high temperature was 42°C. This research has defined the number of environmental condition (Temperatures) over...

he aim of present study was to show crude oil biodegradation by Pseudomonas aeruginosa, K. pneumoniae. The samples of oil were obtain from tanks of crude oil belonging to Kirkuk city/Iraq. The present research was study crude oil biodegradation at a different condition (temperature and pH). The results show the, typical conditions of biodegradation...
