RT Journal Article SR Electronic(1) A1 Heinonen, J.YR 1971 T1 Counting and Sizing of the Individual Cells of Chain-forming Streptococcus thermophilus with an Electric Particle Counter JF Microbiology, VO 66 IS 1 SP 119 OP 121 DO https://doi.org/10.1099/00221287-66-1-119 PB Microbiology Society, SN 1465-2080, AB The number and volume distribution of microbes can be estimated with an electronic particle counter (Kubitschek, 1969). However, when chains of bacteria are present each chain is counted as one large particle. An attempt to overcome this difficulty was made using Streptococcus thermophilus KQ, a chain-forming bacterium, as a test organism. Chains of cells were fixed in formaldehyde and then subjected to ultrasonic treatment to break them down into single units., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-66-1-119
