Across many environments microbial glycoside hydrolases support the enzymatic processing of carbohydrates, a critical function in many ecosystems. Little is known about how the microbial composition of a community and the potential for carbohydrate processing relate to each other. Here, using 1,934 metagenomic datasets, we linked changes in community composition to variation of potential for ca...

Culex pipiens is the mosquito that vectors West Nile Virus and other human-pathogenic flavivruses in North America. In response to shortened day length and lower temperatures, female Cx. pipiense prepares for the diapause by actively feeding on carbohydrates to increase the biosynthesis of glycogen and lipid to store energy for overwintering. The effect of feeding different carbohydrates on gly...

SUMMARY The isolation and genetic analysis of a new class of mutants of the mould Aspergillus nidulans is described. The mutants were detected by their inability to utilize specific carbohydrates as sole carbon source for growth. All of the mutants are recessive and analysis of 27 mutants has resulted in the description of 10 new loci concerned with the utilization of carbohydrates in the organ...

Listeria monocytogenes is a human pathogen causing serious diseases. We aimed to determine food contamination with Listeria spp. in Kermanshah, Islamic Republic of Iran. Samples (185 dairy, 187 meat products and 158 ready-to-eat foods such as salads) were randomly collected from markets. After processing, samples were cultured in half-Fraser and Fraser broth followed by cultivation on PALCAM an...

The various ecological habitats in the human body provide microbes a wide array of nutrient sources and survival challenges. Advances in technology such as DNA sequencing have allowed a deeper perspective into the molecular function of the human microbiota than has been achievable in the past. Here we aimed to examine the enzymes that cleave complex carbohydrates (CAZymes) in the human microbio...

Rapid and accurate immunological confirmation of presumptively positive gonococci could be facilitated with the Phadebact Gonococcus Test, a slide coagglutination procedure. The test was compared with carbohydrate utilization and fluorescent-antibody tests on 235 clinical isolates. With the coagglutination procedure, 97.1% of the isolates were identified as compared with 93.1% by carbohydrate u...

It is well established that carbohydrate utilization is impaired in the fasted animal (1, 2). It has also been recently demonstrated that surviving liver slices prepared from fasted rats are incapable of converting C14-labeled glucose to CO2 and fatty acids to the same extent as are slices from livers of non-fasted rats (3). In an attempt to localize the level at which glucose utilization is su...

Here, we report the draft genome assembly of Lactobacillus fabifermentans strain T30PCM01 isolated from grape marc. Its genome is the largest (3.58 Mbp) among Lactobacillus species and reveals an enormous potential for carbohydrate utilization and transcriptional regulation.

Athletes often train or compete in athletic events that significantly reduce muscle and liver glycogen reserves. Carbohydrate ingestion before or during endurance exercise enhances performance by maintaining blood glucose levels and carbohydrate utilization. Also, an adequate intake of carbohydrate following endurance exercise helps to restore muscle and liver glycogen. This paper reviews the p...

characterized by its gray aerial mycelium color, hygroscopic spore mass and spiral spore chains with warty or spiny spore surfaces. It is nonchromogenic. Strain No. 7238 shows characteristics most closely related to Streptomyces antimycoticus and S. hygroscopicus, although there are differences in physiological characteristics and carbohydrate utilization. In terms of morphological characterist...
