The phrase "a solution of bacteria" is correct and usable in written English.
It can be used in scientific or medical contexts to refer to a liquid mixture containing bacteria, often for experimental or treatment purposes.
Example: "The researchers prepared a solution of bacteria to test the effectiveness of the new antibiotic."
Alternatives: "a bacterial solution" or "a suspension of bacteria."
Dr Charlie Bavington, from GlycoMar, a marine biotechnology company based at the Scottish Association for Marine Science in Oban, explained: "Starfish live in the sea, and are bathed in a solution of bacteria, larvae, viruses and all sorts of things that are looking for somewhere to live.
Another study was conducted by Abdullah et al. (2013) who determined the effects of using a solution of mixed bacteria of Bacillus sp., Clostridium sp., Pseudomonas sp., Aspergillus sp., Cellulomonas sp., Chaetomium sp., Penicillium sp. and Trichoderma sp. as starter culture on kitchen-waste composting consisting of vegetable scraps and fish processing waste in an in-vessel system.
Radial diffusion assays were conducted in petri dishes (diameter 10 cm) filled with PDA (Potato Dextrose Agar, 70139, SIGMA-ALDRICH) covered with a solution of 10 bacteria or spores/ml.
In survival experiments, batches of 20 25 wild-type and mutant flies were challenged by septic injury using a needle previously dipped into a concentrated solution of bacteria.
The bacteria were harvested at d 4 of incubation, transferred to a test tube containing 1 mL of 0.4 % NaCl, and vortexed for 30 s giving a stock solution of bacteria.
To directly study bacteria's effect on bubbles, the team set up an experiment in which they filled a column with a solution of water and various bacteria species, including E. coli.
For the purposes of this study, Leca aggregates were left to soak in a solution of urea-CaCl2 containing bacteria for 6 days to investigate biological improvement of aggregate quality.
To this the technicians added a solution of agrobacterium, a disease bacterium whose modus operandi is to break into a plant cell's nucleus and insert some of its own DNA.
To explore the possible influence of phytoplankton exudates on CDOM and bacteria, a solution of concentrated exudates from a mixed culture (C. socialis and T. weissflogii, in equal concentrations) was used in dark or pseudo-sunlight conditions.
To avoid interaction between LB and U in the future U-treatment, we systematically centrifuged bacteria twice, removed the supernatant and re-suspended bacteria with a solution of 85 mM NaCl to obtain a 20 1 mixture of E. coli (OD600nm of 3 in LB).
By qRT-PCR, the concentration of the stock solution of bacteria was determined and adjusted to 5×107/ml.
