Abstract

This data set summarises the chemotactic response of a model marine bacteria (Vibrio alginolyticus YM4 wild-type) to filtered exudates of the cyanobacteria Synechococcus sp WH8102. Two filtrate sets were collected, each spanning 6 time points (named T1 -> T6), with the initial assays split into 4 biological replicates (named A,B,C,D). The two treatments were: 1) A control treatment (named "Control", or shortened to "C") 2) A phage-infected treatment (named "Phage", or shortened to "P"), wher...

The data in this data set is organized as follows:

Accumulation Curves: The final processed data for each time point (T1-6), each replicate (A-D) with the average and SEM values tabled.

Filtrates_T#R: Where # is the time point number (1-6) and R the replicate (A-D). Each folder contains:

1) Three Excel sheets corresponding to the raw cell counts for each biological replicate (each with 3 repeats)

2) A supplemental folder containing a cell array with the full bacteria positions for each time point for each replicate (.mat format)

The chemotaxis data was collected by Dr. Richard J. Henshaw of Tufts University (Boston, MA, USA) from 3rd December 2020 to 8th October 2021. Queries about this dataset should be directed to rhenshaw@ethz.ch.
