Single Cell Microbiology   For the past few decades, microbiology has mostly relied on bulk data. However, attempts to extract data from single cells have now been used to start understanding heterogeneous populations.

Scientists call for microbiota vault of healthy bacteria   A team of researchers are gathering bacteria from across the world to create a microbiota vault containing healthy bacteria from the human gut and skin.         Multiomics and the Microbiome   Investigation of the microbiome has gained a lot of importance in the last decade. Microbiota populations have been found in human skin, mucosal membranes, and gut where they can influence several disorders, such as diabetes, obesity, cancer, and colitis.

Bioactive Microbial Metabolites   The primary metabolites include polysaccharides, proteins, nucleic, and fatty acids; while the secondary metabolites are low molecular weight (MW<3000) compounds. The secondary metabolites may have antimicrobial, anti-tumour, or anti-viral properties. Non-antibiotic microbial metabolites are often bioregulators or biochemical modulators.       The Lac Operon in E. Coli   Required for the transport and metabolism of lactose in Escherichia Coli (E. coli).The lactose operon or lac operon consists of three structural genes namely lacZ, lacY, and lacA that encode proteins involved in lactose metabolism as well as several regulatory genes.       Staphylococcus Aureus Microbiology   Staphylococcus aureus bacteria are pathogens to both man and other mammals. They are gram positive bacteria that are small round in shape (cocci) and occur as clusters appearing like a bunch of grapes on electron microscopy.       Dysbiosis and the Microbiome   Dysbiosis is a condition wherein there is an imbalance in the bacteria found in the gut. As a result, it will cause symptoms of digestive disturbance. These symptoms include diarrhea, constipation, bloating, and indigestion, among others.       What is Astro Microbiology?   Life in space is of interest to scientists because on Earth, microbes are sometimes the only living organisms found in extreme conditions such as very high or low temperatures, high salt concentrations, high levels of radiation, or limited nutrients in the environment.       Dysbiosis and the Microbiome   Dysbiosis is a condition caused by an imbalance in the bacterial community (microbiome) of the human gut. Dysbiosis disrupts the ecoystsem of the gut, resulting in symptoms such as diarrhea, constipation, bloating, and indigestion, among others.
