Spirulina is a microscopic and filamentous cyanobacterium. It is promoted as a ‘superfood’ that contribute to high energy levels. The important nutrients are polysaccharides and essential fats which are easily absorbed by human cells and help in energy release [1]. Generally, the growth of the bacteria is characterized by five stages. To maintain a healthy […]
The food & beverage industry must make many tests and take certain measurements to ensure that their products meet high standards and are safe for consumption. The Photopette can be used for photometric measurements of liquid samples. The objective of this application note is to demonstrate how Photopette Cell can be used to quantify the […]
E.coli cell counting at OD600 is demonstrated using the Photopette® handheld spectrophotometer [1, 2]. Almost no training is requited. The method is easy and fast performed at the bioreactor or in the cell culture hood. E. coli can be directly measured at 600 nm in the cell culture flask. The method can be performed at […]
