Restriction Enzymes – Molecular Scalpels
The biological function of restriction enzymes is derived from the defense of foreign DNA from invading cells. The restriction-modification system of bacteria makes the DNA bases of bacteria to be methylated and modified, so that they are not recognized and cut by their own restriction enzymes. The development of restriction endonucleases In the early 1960s, Werner Arber came up with the idea ...

Efficient Wastewater cleaning for Insulin Production
Insulin production using biotechnology is now a standard procedure, but it leads to a high level of contaminated wastewater due to tensides which are difficult to break down. A solution provided by EnviroChemie shows how production wastewater output with varying levels of contamination and toxicity can be cleaned efficiently. It combines aerobic and anaerobic steps as well as a low-temperature ...

CD Genomics Perspective: DNA-Based Technologies for Detection of Foodborne Microorganisms
Food-borne diseases are complex in nature and appear to pose serious public health issues worldwide. In humans, certain pathogens cause illnesses that are spread by different food products. Consumers, businesses, and regulatory authorities have been very concerned about the microbiological quality of food. Contamination can occur by air, water, soil contamination and at different points during ...

Plasmid Detection and Complete Plasmid DNA Sequencing
Bacterial plasmids Bacterial plasmids are circular or linear double-stranded DNA molecules defined by their capability of autonomous replication in the hosts. They are critical sources for microbial evolution and genome innovation due to their ability to acquire foreign DNA sequences and transfer among bacteria and between distantly related organisms, like transferring from bacteria to eukaryotes ...

Bartonella quintana: Putting the re-emerging in emerging infection
Introduction Trench fever was a defining feature of World War I. Notables like A.A. Milne, author of Winnie-the-Pooh, and fantasy writer JRR Tolkien were treated for trench fever. But surely trench fever did not just appear in the European trenches of World War I and then disappear after. What’s the rest of the story? Before World War I, Way Before While infections caused ...

What is the difference between infection and disease?
Disease-causing microbes are often found in the human microbiome. So, when does the presence of pathogenic microbes indicate an infection? And when does the presence of infection explain disease? What is an infection? What is a disease? A disease associated with microbes is the outcome of interaction(s) between a microbe(s) and its host in which the host suffers some sort of damage. ...
