Foods with too much salt and sugar affect the microbiome (肠道菌群) in your body by killing the right bacteria (细菌) in it. These bacteria protect you from illness and keep your mind sharp. Lacking them can lead to being overweight and depression. Rob Knight is a scientist at the Unive...
and promote the colonization of N-fixing rhizobia and other plant growth promoting rhizobacteria (PGPR) in the rhizosphere of host plants [8,9,10]. The AMF also facilitated bacterial translocation and boosted the combination of plants with beneficial fungi and bacteria via a wide network of extra...
time, a trained microbiologist can identify the bacteria, if present, and confirm its identity by looking at biochemical reactions. Typically, this test is conducted at a hospital or clinical laboratory. Isolates obtained from culture are forwarded from clinical laboratories to public health ...
Cases are interviewed by public health staff about possible sources for their infection (i.e., food, water, animal contact, ill people). In addition, the stool sample that tested positive, or the bacteria itself (called an “isolate”), is sent to the public health laboratory for ...
The immune system’s goal is simple: protect the body from viruses, bacteria, malignant cells, and other dangers without damaging normal cells. Several types of immune cells work together to achieve this goal (Table 1). Cells of the innate immune system are the body’s first line immune res...
In the past decade, nanozymes - a unique class of nanomaterials with inherent enzyme-mimetic properties - have fascinated researchers, revealing unexpected enzyme-like activity of nanomaterials previously considered biologically inert. In particular, as metal-free catalyst for biological processes, carbon-...
Finally, there is one type of dairy that you might want to get more of; yogurt containsbeneficial lactobacillus bacteriathat can help keep you regular. There’s no need to pay extra for the yogurt with the suggestive downward arrow on the package, though. The beneficial bacteria in regular ...
in his first job as a scientist, he discovered that organic molecules are asymmetrical. Finding organic molecules in beer and wine led him to recognize that microorganisms such asLactobacillusfunctioned as the agents of fermentation and food spoilage. This understanding of the role of bacteria helped...
in the laboratory, bacteria of the same species may need several days to double in especially harsh environments. Most pathogens grow rapidly, likeE. coli, but there are exceptions. For example,Mycobacterium tuberculosis, the causative agent of tuberculosis, has a generation time of between 15 and...
cultured plant cell developmental fates, the underlying molecular mechanisms are still largely unexplored. Investigations have recently been empowered by the identification of key genes that function in regeneration, involved in hormonal biosynthesis, transport, signaling, and hormone interactions. The ...
