Migration of chemotactic bacteria in soft agar: role of gel concentration [PDF]
Biophys. J. Volume 101, Issue 3, 3 August 2011, Pages 525-534, 2011 We study the migration of chemotactic wild-type Escherichia coli populations in semisolid (soft) agar in the concentration range C = 0.15-0.5% (w/v). For C < 0.35%, expanding bacterial colonies display characteristic chemotactic rings. At C = 0.35%, however, bacteria migrate as broad circular bands rather than sharp rings.

Cyclic β-glucans at the bacteria–host cells interphase: One sugar ring to rule them all [PDF]
, 2018 Cyclic β‐1,2‐D‐glucans (CβG) are natural bionanopolymers present in the periplasmic space of many Proteobacteria. These molecules are sugar rings made of 17 to 25 D‐glucose units linked exclusively by β‐1,2‐glycosidic bonds.

Ferric uptake regulator Fur is conditionally essential in Pseudomonas aeruginosa [PDF]
, 2017 In Pseudomonas aeruginosa, the ferric uptake regulator (Fur) protein controls both metabolism and virulence in response to iron availability. Differently from other bacteria, attempts to obtain fur deletion mutants of P. aeruginosa failed, leading to the

RamanNet: A generalized neural network architecture for Raman Spectrum Analysis [PDF]
arXiv, 2022 Raman spectroscopy provides a vibrational profile of the molecules and thus can be used to uniquely identify different kind of materials. This sort of fingerprinting molecules has thus led to widespread application of Raman spectrum in various fields like medical dignostics, forensics, mineralogy, bacteriology and virology etc.

Optical elastic scattering for early label-free identification of clinical pathogens [PDF]
Advanced Biomedical and Clinical Diagnostic and Surgical Guidance
Systems, 2016, san francisco, United States. pp.96980 - 96981, 2016, 2016 We report here on the ability of elastic light scattering in discriminating Gram+, Gram-and yeasts at an early stage of growth (6h). Our technique is non-invasive, low cost and does require neither skilled operators nor reagents. Therefore it is compatible with automation.
