It grows effectively at high temperatures ( 30-40 �C ) which are typical of the Indonesian islands, it exhibits strong lipolytic and proteolytic activity that create desirable properties in tempeh and it produces metabolites that allows it to inhibit and thus outcompete other molds and gram-positive bacteria, including the potentially harmful " Aspergillus flavus " and " Staphylococcus aureus ".

In turn the starch ingredients used also alter the microbial ecology dictating both the type and amount of metabolites present, e . g . " Aspergillus oryzae " and " Rhizopus oryzae " both produce more starch degrading enzymes and are found commonly on 100 % flour substrates, whilst " Actinomucor " and " Mucor " produce more proteolytic and lipolytic enzymes and are more abundant when pulse flours are added.

The lipolytic effect of 1 mM / L of synephrine on rat white fat cells was antagonized by various ?-antagonists with the following inhibitory concentrations ( IC 50 ) : bupranolol : 0.11 ?M; CGP-20, 712A ( ? 1 antagonist ) : 6.09 ?M; ICI-118, 551 ( ? 2 antagonist ) : 3.58 ?M; SR-5923A ( ? 3 antagonist ) : 17 ?M.
