Article
Full-text available
The production of glyoxal from ethylene glycol has been demonstrated with the use of glycerol oxidase and catalase as catalyst from Aspergillus versicolor. Glycerol oxidase was formed in the mycelia of the fungi grown on ethylene glycol as the sole carbon source. Catalase activity is essentially important as co-catalyst to decompose by-product hydr...
Article
The fermented milk matsoni is a traditional, national food product of both Georgia and Armenia. Little is known about the effects of biogeography and milk type on the microbial biodiversity of matsoni or the fungal composition of matsoni fermentations. High-throughput marker-gene sequencing was used to survey the bacterial and fungal communities of...
Article

The production of glyoxal from ethylene glycol by the use of mycelial granules of fungi with high glycerol oxidase and catalase activity was studied. The optimum pH and temperature for the oxidation of ethylene glycol were around 8.0 and 52oC, respectively. The apparent Kms for ethylene glycol and glycolaldehyde were 201 and 52.8mM, respectively. T...

Food contact materials (FCM) made from PVC, such as e.g. gaskets of metal lids or cling films, may release plasticizers into the packed food. Such migration repeatedly exceeded legal limits or nonauthorized plasticizers have been used. Legal limits were exceeded in 24% of the 38 samples analyzed. The EU also banned the use of certain phthalates as...

1. Multiple Locus Sequence Typing (MLST) is a typing method used to characterize the strains in different sequence types (ST) on the basis of allelic profile of housekeeping genes. Salmonella enterica serovar Paratyphi A is becoming an important cause of enteric fever. 2. There is a need for rapid and reliable typing method for identification in fo...

A memory structural model is generated directly from memory configuration information and memory layout information in an efficient manner. Information on strap distribution is generated by analyzing configuration information of the memory and the corresponding memory layout. Information on scrambling of addresses in the memory layout is generated...
Conference Paper

The issues of microbial deteriorations and degradations of synthetic polymers and related compounds are one of the most important fields of modern biotechnology. The increasing rate of production and use of synthetic polymeric materials initiated many essentially important problems dealt with environment control and rational application of polymers...

This paper presents a robust solution for test and repair of embedded memories. The STAR (Self-Test and Repair) Memory System solution is developed within Synopsys Design Ware allowing users to create, integrate and verify embedded memory test and repair IP in system on chips. The key components and features of the SMS are discussed.
Conference Paper
Nowadays, the microbiological production of biofuels has great importance worldwide, proceeding from its benefits i.e. renewability, low self-cost, low level of environment pollution, etc. For Armenia, a republic without oilfields, which is importing all the fuel demand from neighbor countries and which has huge experience in microbiological produc...
