Technician with bacterial cultures in petri dishes
MODEL RELEASED. Bacterial cultures. Masked techni- cian holding two petri dishes containing bacterial cultures in gloved hands. The petri dishes are filled with different coloured agar nutrient media on which bacteria grow. Lines of bacteria can be seen growing on the dishes where they were streaked. This involves running a platinum wire loop that has been placed in contact with a bacterial culture over the agar. By heating the loop, each successive set of streaked lines leaves fewer bacteria, until round colonies form around single bacteria. This technique is used to isolate particular strains of bacteria, which may then be incubated and grown in pure form

EDITORS COMMENTS
In this photo print, a masked technician delicately holds two petri dishes filled with vibrant agar nutrient media. These dishes are home to various bacterial cultures, each displaying distinct streaks of growing bacteria. The skilled technician has used a platinum wire loop to streak lines on the agar, gradually reducing the number of bacteria until round colonies form around individual cells. This meticulous technique serves an important purpose in microbiology - isolating specific strains of bacteria for further study and analysis. By incubating and growing these isolated strains in pure form, scientists can unravel their unique characteristics and potential applications in medicine and healthcare. The image showcases the dedication and precision required in laboratory research. The gloved hands of the technician emphasize the importance of maintaining sterile conditions throughout the process. Behind the protective face mask lies a wealth of knowledge and expertise as they navigate through this intricate world of microorganisms. As we gaze at this snapshot from Science Photo Library, we are reminded of how essential such scientific endeavors are for advancing our understanding of biology and improving human health. It is through these painstaking efforts that breakthroughs occur, leading us towards new discoveries that shape our future wellbeing.
