Lactiplantibacillus plantarum is a Gram-positive bacterium that belongs to the lactic acid bacteria (LAB) group commonly used in food industry. To use this microorganism, high biomass concentration necessary, and models need be established for predicting improving its behavior along fermentation. However, current L. are applicable only one substrate. The growth of newly isolated strain 60-1 co-...

At CHES 2003, Piret and Quisquater published a very efficient DFA on AES which has served as a basis for many variants published afterwards. In this paper, we revisit P&Q’s DFA on AES and we explain how this attack can be much more efficient than originally claimed. In particular, we show that only 2 (resp. 3) faulty ciphertexts allow an attacker to efficiently recover the key in the case of AE...

Biosurfactants are microbial substances which influence interfacial tension. The kinetic study was carried out for Pseudomonas aeruginosa MR01 during biosurfactant production in a two-phase liquid-liquid batch fermentation system. The maximum rhamnolipid concentration (P ) and the yield of biosurfactant per max biomass (Y ) in a 5-L bioreactor containing soybean oil medium were found to be appr...

Skolpap, W., Scharer, J.M., Douglas, P.L. and Moo-Young, M. Optimal feed rate profiles for fed-batch culture in penicillin production Songklanakarin J. Sci. Technol., 2005, 27(5) : 1057-1064 The fed-batch optimization of penicillin productivity was applied as an example of optimization algorithm verification. The objective function of this problem was to optimize penicillin productivity by dete...

A construction is described of high-rate RS-like convolutional codes, and a lower bound is given on their free distance. These codes can be used to construct asymptotically good binary convolutional codes. 1. Introduetion I~ a preceding report 4), a class of RS-like convolutional codes was introduced. These codes were obtained only for length n, rate R = kln and constraint length 'll related by...

level: advanced M athematically modeling the kinetics of batch and continuous cultivation allows you to not only calculate and evaluate the effects of process parameters, but also to forecast those parameters and duration of cultivation to develop a costeffective production process. Mathematical modeling microorganism cultivation was intensively developed in the second half of the last century....

19 20 The production dynamics of yessotoxin (YTX) by Protoceratium reticulatum and 21 phosphate uptake in culture were investigated in relation to cell growth. The equations 22 used were: the reparametrized logistic for cell production, Luedeking-Piret model for 23 yessotoxin production and maintenance energy model for phosphate consumption. 24 Thus, the YTX formation rate was proportional to p...
