Many yeast species have simple nutritional requirements, they are able to colonize dry surfaces for long periods of time and they can grow rapidly on inexpensive substrates in bioreactors, characteristics that are relevant in the selection of BCAs (Chanchaichaovivat et al., 2007). Moreover, they do not produce allergenic spores or mycotoxins as many mycelial fungi or antibiotics which might be produced by bacterial antagonists (El-Tarabily and Sivasithamparam, 2006; Nunes, 2012)
