Gram-positive bacteria, which have single membranes, use peptides, which are small chains of amino acids.
Gram-negative bacteria – which have outer membranes – tend to be more resistant to antibiotics.
Gram-negative bacteria — which have outer membranes — tend to be more resistant to antibiotics.
There are 10 times as many bacteria (which have their own DNA) in our gut than there are cells in our bodies.
In the activated sludge process, aerobic ciliates consume aerobic bacteria, which have flocculated (formed loose aggregates, making them easily separated from liquid).
Lipopolysaccharides (LPS) are essential constituents of the outer membranes of Gram-negative bacteria, which have been widely applied to establish ALI models.
The consortium was mainly constituted by three bacteria, which have a close affiliation to Kocuria rhizophila, Staphylococcus epidermidis and Staphylococcus aureus.
To the authors' knowledge, this is the first report about the construction of engineering bacteria which have the advantages of both high temperature resistance and high polysaccharide production.
This study demonstrated that arsenic could be removed through volatilization from the contaminated soil by bacteria which have arsM gene expressed.
The man tackling the problem in the labs at Northumbria is Dr Alan Richardson and his weapons are a couple of bacteria which have the delightful classification of 'extremeophile'extremeophile
Scientists have found that in Gram-negative bacteria, which have double cell membranes, the signaling molecules are homoserine lactones, molecules that resemble amino acids, the building blocks of proteins.
