Bacteria are among the most versatile and widely used organisms in biotechnology. Their rapid growth, genetic flexibility, and metabolic diversity allow them to function as living systems that can be engineered to produce valuable products, carry out complex chemical reactions, and solve real-world problems. From medicine and manufacturing to environmental sustainability, bacteria are central to modern biotechnology. Bacteria are single-celled prokaryotic organisms that lack a nucleus but contain all essential cellular components needed for life. They reproduce through binary fission, allowing populations to expand rapidly under favorable conditions. This rapid reproduction is one of the key reasons bacteria are so useful in biotechnology. In addition to their fast growth, bacteria have relatively simple genomes that are easier to study and manipulate compared to those of eukaryotic organisms. Many bacterial species can survive in extreme environments, giving them unique metabolic capabilities that can be harnessed for industrial and environmental applications. Because of these features, bacteria are often described as biological “factories” that can be programmed to produce specific products.
- 12.2: Transformation
- This page discusses the transformation process in bacteria, where they absorb environmental DNA, thereby increasing genetic diversity. In biotechnology, bacteria are made competent to take up foreign DNA using recombinant plasmids. Two methods for transformation are highlighted: the calcium chloride method, which uses heat shock, and electroporation, which employs electrical pulses. Both techniques aid in introducing beneficial genetic material into bacteria for diverse applications.
