The aim of this work was to assess OchratoxinA (OTA) production of different Aspergillus carbonarius isolates, evaluate their growth profile through different growth measurements, and reveal any underlying correlation between them. Ten different isolates of A. carbonarius isolated from Greek vineyards located in different geographical regions were examined in vitro for their OTA production pote...
Studies on Co-Culture fermentation of tapioca flour as the substrate symbiotic strains of starch digesting Aspergillus niger and non starch digesting and sugar fermenting Saccharomyces Cerevisaie in a batch fermentation. The effect of Carbon to Nitrogen (C/N) ratio of the fermentation medium on ethanol concentration and biomass was investigated. The optimum C/N ratio of the fermentation medium ...

We consider the correspondence between the Jordan frame and the Einstein frame descriptions of scalar-tensor theory of gravitation. We argue that since the redefinition of the scalar field is not differentiable at the limit of general relativity the correspondence between the two frames is lost at this limit. To clarify the situation we analyse the dynamics of the scalar field in different fram...
In a distributed clustering algorithm introduced by Coffman, Courtois, Gilbert and Piret [1], each vertex of Zd receives an initial amount of a resource, and, at each iteration, transfers all of its resource to the neighboring vertex which currently holds the maximum amount of resource. In [4] it was shown that, if the distribution of the initial quantities of resource is invariant under lattic...
in the present study lactic acid production was enhanced by optimizing the three process variables viz; inoculum size, temperature and ph using three factor five level ccrd (central composite rotatable design) by lactobacillus delbruckii under smf (submerged fermentation process). paneer (dairy by-product) whey was used as sole substrate for lactic acid production. design expert 8.0.2.0 softwar...
The simultaneous production of amylase (AA) and protease (PA) activity by Bacillus subtilis UO-01 in brewery wastes was studied by combining the response surface methodology with the kinetic study of the process. The optimum conditions (T=36.0°C and pH=6.8) for high biomass production (0.92g/L) were similar to the conditions (T=36.8°C and pH=6.6) for high AA synthesis (9.26EU/mL). However, the ...
The Matsumoto-Imai public key scheme was developed to provide very fast signatures. It is based on substitution polynomials over GF( 2 ). This paper shows in two ways that the Matsumoto-Imai public key scheme is very easy to break. In the faster of the two attacks the time to cryptanalyze the scheme is about proportional to the binary length of the public key. This shows that Matsumoto and Imai...
