Apart from growing fungi for nutrition, as seen in the New World Attini, ants cultivate fungi for reinforcement of the walls of their nests or tunnel-shaped runway galleries. These fungi are grown on organic material such as bark, epiphylls or trichomes, and form stable 'carton structures'. In this study, the carton of the runway galleries built by Azteca brevis (Formicidae, Dolichoderinae) on ...

Prioritization of sugar consumption is a common theme in bacterial growth and a problem for complete utilization of five and six carbon sugars derived from lignocellulose. Growth studies show that Lactobacillus brevis simultaneously consumes numerous carbon sources and appears to lack normal hierarchical control of carbohydrate utilization. Analysis of several independent L. brevis isolates ind...

A global model of the lactic fermentation step of gowé was developed by assembling blocks hosting models for bacterial growth, lactic acid production, and the drop of pH during fermentation. Commercial strains of Lactobacillus brevis and of Lactobacillus plantarum were used; their growth was modeled using Rosso's primary model and the gamma concept as a secondary model. The optimum values of pH...

This work examines the historical records of red tides in the western Gulf of Mexico (GOM) as they pertain to the toxic dinoflagellate Karenia brevis (Davis) G. Hansen and Moestrup. K. brevis commonly causes major fish kills, human respiratory distress, and significant economic disruption in the Gulf of Mexico. It can also lead to illness by consumption of contaminated shellfish. The nearly ann...

Although squid are generally considered to be effective predators, little is currently known of how squid maneuver and position themselves during prey strikes. In this study, high-speed video and kinematic analyses were used to study attacks by the brief squid Lolliguncula brevis on both shrimp and fish. Squid attack success was high (>80%) and three behavioral phases were identified: (1) appro...

We present here the draft genome sequence of Lactobacillus brevis strain 3M004, a probiotic that has potential for regulating quorum sensing. The strain was obtained from a type of aquafeed. The assembly consists of 2,459,326 bp and contains 33 contigs, with a G+C content of 45.10%.
