Biomass (e.g., plant biomass, animal biomass, microbial, and municipal waste biomass) is processed to produce useful products, such as food products and amino acids.

The present invention discloses biotechnologically produced inactive aroma- and fragrance/scent precursors in new concentration ranges beyond those of natural aroma glycoside sources, which can be activated by external triggers like enzymes, temperature and p H, and then release the aroma and the fragrance.

Novel compounds, called liamocins from Aureobasidium pullulans, having the general structure in Formula 1 are disclosed. ##STR00001##
where R.sub.1 is either COCH.sub.3 or H; and R.sub.2 is between two to ten O-linked 3,5-dihydroxydecanoate; and R.sub.3 can be a polyol (e.g., L- or D-glycerol, L- or D-threitol, L- or D-erythritol, L- or D-arabitol, L- or D-xylitol, L- or D-lyxitol, L- or D-ribitol, L- or D-allitol, L- or D-altritol, L- or D-mannitol, L- or D-iditol, L- or D-gulitol, L- or D-glucitol (also called sorbitol), L- or D-galactitol (also called dulcitol), and L- or D-talitol), 2-amino-D-mannitol, 2N-acetylamino-D-mannitol, L-rhamnitol, or D-fucitol; except when R.sub.3 is D-mannitol, R.sub.2 is not 2 nor 3 O-linked 3,5-dihydroxydecanoate chains. These liamocins described above in addition to D-mannitol liamocin A1, D-mannitol liamocin A2, D-mannitol liamocin B1, and D-mannitol liamocin B2, alone or in combination with each other, can be used to kill certain bacteria and to treat certain bacterial infections.
