16s Ribosomal Dna Sequencing Confirms The Synonymy Of Vibrio Harveyi And V. Carchariae, Eric J. Gauger, Marta Gomez-Chiarri Dec 2012

16s Ribosomal Dna Sequencing Confirms The Synonymy Of Vibrio Harveyi And V. Carchariae, Eric J. Gauger, Marta Gomez-Chiarri

Marta Gomez-Chiarri

Seventeen bacterial strains previously identified as Vibrio harveyi (Baumann et al. 1981) or V. carchariae (Grimes et al. 1984) and the type strains of V. harveyi, V. carchariae and V. campbellii were analyzed by 16S ribosomal DNA (rDNA) sequencing. Four clusters were identified in a phylogenetic analysis performed by comparing a 746 base pair fragment of the 16S rDNA and previously published sequences of other closely related Vibrio species. The type strains of V. harveyi and V. carchariae and about half of the strains identified as V. harveyi or V. carchariae formed a single, wellsupported cluster designed as ‘bona fide’ …

Current models for nucleotide sugar use in the Golgi apparatus predict a critical role for the lumenal nucleoside diphosphatase. After transfer of sugars to endogenous macromolecular acceptors, the enzyme converts nucleoside diphosphates to nucleoside monophosphates which in turn exit the Golgi lumen in a coupled antiporter reaction, allowing entry of additional nucleotide sugar from the cytosol. To test this model, we cloned the gene for the S. cerevisiae guanosine diphosphatase and constructed a null mutation. This mutation should reduce the concentrations of GDP-mannose and GMP and increase the concentration of GDP in the Golgi lumen. The alterations should in turn …


Viability Of Lactic Acid Bacteria And Sensory Evaluation In Cinnamomum Verum And Allium Sativum-Bio-Yogurts Made From Camel And Cow Milk, Ahmad Salihin Hj Baba, Shori A. B. Dec 2011

Viability Of Lactic Acid Bacteria And Sensory Evaluation In Cinnamomum Verum And Allium Sativum-Bio-Yogurts Made From Camel And Cow Milk, Ahmad Salihin Hj Baba, Shori A. B.

The present study investigate the effect of herbal water extract prepared from Allium sativum and Cinnamomum verum on the viability of lactic acid bacteria (Lactobacillus spp and Streptococcus thermophilus) in cow- and camel-milk yogurts during 21 day refrigerated storage. The organoleptic properties of fresh-yogurts were evaluated. Lactobacillus spp count for fresh cow milk-yogurts (0 day) in both present and absent of C. verum and A. sativum was ranged from 1.4×0 6 to 2.1×10 6 cfu/mL. These values were not significantly changed throughout the 21 days of refrigerated storage. Lactobacillusspp count in fresh plain camel milk- yogurt was 13.2×10 6 cfu/mL …
