| Sumario: | Although polystyrene (PS) is considered a non-biodegradable material, recent
work has shown the degradation capacity of this material by microorganisms,
especially those that are part of the natural microbiota of the digestive tract of
some invertebrates. The present work sought to evaluate the growth of the larva
of the mealworm (Tenebrio molitor) and its bacteria, using PS as the sole source of
carbon. In this way it was possible to demonstrate the consumption of PS plates
by the larva, found in holes and tunnels in the material, however, nutritionally
it is not enough for the larva to gain biomass, notably reducing its size and time
survival. Similarly, bacteria isolated from the digestive tract of T. molitor presented
the ability to generate biofilms o n P S s heets, g enerating c hanges ( cracks, holes,
etc.) in them, which were observed under scanning electron microscopy (SEM),
indicating the possible use of this material as a carbon source for its growth. |
