- •
Official methods for detecting bacteria are culture-dependent.
- •
Limitations of these methods are high time consumption, costs and detection limits.
- •
Capability of sensitive spectral and hyperspectral techniques was investigated.
- •
The potential of near and the infra-red spectral regions were explored.
- •
Multivariate exploratory data analysis was applied to extract useful information.
