The repertoire of hydrolytic enzymes natively secreted by the filamentous fungus Ashbya (Eremothecium) gossypii has been poorly explored. Here, an invertase secreted by this flavinogenic fungus was for the first time molecularly and functionally characterized. Invertase activity was detected in

The complexity of microbial biofilms offers several challenges to the use of traditional means of microbial research. In particular, it can be difficult to calculate accurate numbers of biofilm bacteria, because even after thorough homogenization or sonication, small pieces of

Plants produce a myriad of taxonomically restricted specialized metabolites. This diversity-and our ability to correlate genotype with phenotype-makes the evolution of these ecologically and medicinally important compounds interesting and experimentally tractable. Trichomes of tomato and other nightshade family plants produce
