Introduction | Bacillus is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Bacillota. Bacillus species can be either obligate aerobes which are dependent on oxygen, or facultative anaerobes which can survive in the absence of oxygen. |
Alternative Names | B. licheniformis |
Bacillus licheniformis thrives in nutrient-rich media such as LB broth or TSB. Supplementing with trace elements like magnesium and manganese can enhance growth and metabolic activity, which is crucial for experimental studies.
The enzymatic activity can be measured using spectrophotometric assays that monitor the release of products from specific substrates. For instance, protease activity is often assessed by hydrolyzing casein and measuring the resulting peptides.
Lyophilization involves freezing Bacillus licheniformis cultures at -80°C, followed by vacuum drying. Adding cryoprotectants like glycerol before freezing can help maintain cell viability during the lyophilization process.
Common methods include electroporation and heat shock transformation. These techniques require the preparation of competent cells and the use of plasmid DNA or other vectors to introduce new genetic material into the bacteria.
To prevent contamination, work in a sterile environment using aseptic techniques. Sterilize all equipment and media before use, and regularly monitor cultures for signs of contamination such as unexpected growth or changes in turbidity.
