Article Abstract

Sphaerotilus natans is a filamentous sheath-forming bacterium. A method of selective fluorescent-labeling of its sheath using conventional reagents was developed. Terminal expansion of the sheath was confirmed by this method. In addition, ubiquitous cell growth was revealed by sequential phase-contrast microscopy of a filament. Based on this and earlier reports, a model of the sheath formation is proposed.

Article Synopsis
  • Airport de-icing has been shown to contribute to the growth of undesirable river biofilms (URBs), which can lead to long-term ecological issues in waterways.
  • The study aimed to identify which freeze-point depressants (FPDs) promote growth in a specific filamentous bacterium associated with URBs, compare the effectiveness of different FPDs and commercial airport de-icers (CADs), and analyze the influences of carbon sources on microbial growth.
  • Findings indicated that the bacteria thrive on various FPDs, with sodium acetate facilitating the fastest growth, while propylene glycol and ethylene glycol showed varying strengths in total growth and growth rate, highlighting limited effects from additives in commercial products on the bacterium's growth.

Bacterial hemoglobins play important roles inside the cell. Phylogenetically, they belong to three different families: the single domain hemoglobin, flavohemoglobin and truncated hemoglobin. Vitreoscilla hemoglobin (VHb) is the first characterized bacterial hemoglobin, and belongs to the single domain hemoglobin family.
