We have obtained evidence for two structurally and antigenically different Saccharomyces cerevisiae cell wall mannans. One, which occurs widely and is found in S. cerevisiae strain 238C, is already known to be a neutral mannan which yields mannose, mannobiose, mannotriose, and mannotetraose on acetolysis of the (1 --> 6)-linked backbone. The other, which was found in S. cerevisiae brewer's stra...
The spoilage of beer by bacteria is of great concern to the brewer as this can lead to turbidity and abnormal flavors. The polymerase chain reaction (PCR) method for detection of beer-spoilage bacteria is highly specific and provides results much faster than traditional microbiology techniques. However, one of the drawbacks is the inability to differentiate between live and dead cells. In this ...
Bottlenose dolphins (Tursiops truncatus) along the Gulf of Mexico are frequently exposed to blooms of the toxic alga, Karenia brevis, and brevetoxins associated with these blooms have been implicated in several dolphin mortality events. Studies on brevetoxin accumulation in dolphins have typically focused on analyses of carcasses from large-scale die-offs; however, data are scarce for brevetoxi...
Corresponding Author: Jian Mao, State Key Laboratory of Food Science and Technology, School of Food Science and Technology, Jiangnan University, Wuxi 214122, China Tel: +86-510-8532-9062, Fax: +86-510-8591-2155, E-mail: [email protected] Abstract: Previous studies showed that γ-aminobutyric acid (GABA) can protect some GABA-producing bacteria against acid stress through glutamate decarboxylat...
Red tide blooms formed by Karenia brevis are frequent along the Gulf coast of Florida and it is unclear what tolerance the green mussel Perna viridis, a recently introduced species to coastal waters, has toward these events. Established populations of P. viridis were monitored along the coastal waters of Estero Bay, Florida before, during and following two consecutive red tide blooms to assess ...
The peroneal tubercle is an osseous structure on the lateral side of the calcaneus present in 90% of individuals. Hypertrophy of the peroneal tubercle resulting in stenosing peroneal tenosynovitis has been well described in the literature. Repair of this condition involves operative treatment to remove the hypertrophied peroneal tubercle and repair any resulting tendon pathology. The authors re...
BACKGROUND Functional loss is a common complication of the fractured distal part of the radius. The purpose of the present study was to determine if the moment arms of the first dorsal extensor compartment are altered by distal radial fracture malunion. We hypothesized that the moment arms of the abductor pollicis longus and extensor pollicis brevis are significantly affected by dorsal angulati...
To better understand the role of caspase-like proteins in the cellular activities of harmful dinoflagellates, cultures of Karenia brevis and Karenia mikimotoi were monitored over a 56-day period. The cellular abundance, maximum photochemical efficiency of photosystem II (Fv/Fm), percentage of dead cells (revealed by SYTOX-labelling of nuclei of cells with a compromised membrane) and the variati...
Two new surface layer (S-layer) proteins (SlpB and SlpD) were characterized, and three slp genes (slpB, slpC, and slpD) were isolated, sequenced, and studied for their expression in Lactobacillus brevis neotype strain ATCC 14869. Under different growth conditions, L. brevis strain 14869 was found to form two colony types, smooth (S) and rough (R), and to express the S-layer proteins differently...
Biotic interactions in the plankton can be both complex and dynamic. Competition among phytoplankton is often chemically mediated, but no studies have considered whether allelopathic compounds are modified by biotic interactions. Here, we show that compounds exuded during Karenia brevis blooms were allelopathic to the cosmopolitan diatom Skeletonema costatum, but that bloom allelopathy varied d...
