The residue of L-Threonine fermentation is named Biofert Plusz and is
grouped into the class of UVCB-substances. The aqueous suspension
contains deactivated E.coli K12 biomass, amino acids and residual
fermentation nutrients. The freeze-dried product is a brown powder at
standard conditions. The melting point of Biofert Plusz was investigated
in a study conducted according to OECD Guideline 102 and EU Method A.1.
Based on the results of DSC measurements and the capillary method, the
test substance melted under decomposition in the temperature range of
250 -271°C. According to REACH Regulation (Annex VII, 7.3, column II),
the study on the boiling point does not need to be done for substances
which decompose before boiling. In a study conducted according to OECD
Guideline 109, EU Method A.3, and DIN 66137-2, the density (at 21.5°C)
and the relative density (D21.5/4) of Biofert Plusz were determined to
be 1.38 g/cm³ and 1.38, respectively. No experimentally derived test
results are available for particle size distribution. According to REACH
Regulation (Annex VII, 7.14, column II), a study on granulometry does
not need to be conducted if the substance is marketed or used in a non
granular or non solid form. Biofert Plusz is marketed and used solely as
