Why the fluorescens of Phosphorus bacillus can not be observed via eyes after culture?

04 September 2022 1 2K Report

Hello everyone, I am culturing the Phosphorus bacillus (Photobacterium phosphoreum

DSM 15556). After culture, the fluorescens can be detected via luminometer (over 3 million), but can not observe the fluorescens via eyes (baed on the website images, a very bright blue fluorscens can be observed from culture medium). So, how I should do to observe the fluorescens? Thanks in advance.

Paul Reed Hepperly

For many of the beneficial bacteria bacteria there fluorescence is not visible in the visiible light spectrum but there fluorsecence is found and detected under ultraviot light exposures.
