The invention concerns a simple and effective process for preparing -carotene or lycopene by submerged fermentation with mixed cultures of (+) and () strains of the fungus Blakeslee trispora, characterized by high productivity of the B. trispora strains. The high productivity is achieved by virtue of the inventive regime, which acknowledges both the morphological state of the hemi-strains with their filamentous growth state when the strains are mixed (referred to as mating).

After a longer time, felt like a stagnation of hydrogen technology development, nowadays, more activities in the field are apparent considering generation, storage and use of hydrogen. Temporary high surplus of electricity from so-called green energies has led worldwide to new considerations. In addition, the very first technical hydrogen generation at larger scale was based on green energy sources such as waterpower - due to economic reasons. Hydropower plants in Europe and Northern America were used to produce hydrogen as a side or main product. For the first time, in Askov (Denmark) hydrogen was generated from wind energy conversion into electricity. The paper gives an overview mainly over the beginning of electrochemical hydrogen production. Development in future is discussed.

The invention relates to a composition of active ingredients for fighting plant diseases, composed of at least two different active substances, selected from the group of stilbenes and/or derivatives thereof on the one hand and of the group of galloylated flavan-3-ols and/or derivatives thereof, and/or of the group of proanthocyanidins and/or derivatives thereof on the other hand. As an alternative, the at least two different active substances can be selected from the group of galloylated flavan-3-ols and/or derivatives thereof and/or from the group of proanthocyanidins and/or derivatives thereof. The novel mixtures have a higher effect than the individual components, there is a synergistic effect. The invention further relates to a method for fighting fungal plant diseases using the aforementioned active ingredients.

BIOFECTOR is an integrated project that develops alternative fertilisation strategies by the use of various bio-effectors (BEs, plant growth promoting microorganisms and natural extraction products). BEs stimulate root growth, solubilise and mineralise sparingly available nutrients, or protect plants from abiotic and biotic stresses. Novel BEs will be isolated, characterized and applied in strategic combination with alternative fertilisation strategies that include organic and low-input farming, use of waste recycling fertilizers, and fertiliser-placement technologies. Bio-effectors addressed comprise fungal strains of Trichoderma, Penicillium and Sebacinales, as well as bacterial strains of Bacillus and Pseudomonades with well-characterized root growth promoting and nutrient solubilising potential. Natural extraction products of seaweed, compost and plant extracts, as well as their purified active compounds are also tested in various combinations. Maize, wheat and tomato are chosen as representative crops. Laboratory and European-wide field experiments assure product adaptation to divers geo-climatic conditions. Viable alternatives to the conventional practice of mineral fertilisation are developed, towards environmental friendly agricultural practice with reduced agrochemical input.


Electrodeionization is a combination of ion exchange with electrodialysis. The method is applicable both for ultrapure water production and environmentally-oriented purposes. However, application in ultrapure water preparation is dominating in practice up to now. The paper reviews the development of electrodeionization and presents the state of art. Basis constructions are shown and main problems are discussed. Occurrence of large differences in resin and electrolyte conductivity is one of the most decisive problems because it hinders continuous electrodeionization operation mode. The way out of the dilemma is the consecutive resin loading and its electrochemical regeneration. A calculation explains the method.

Regeneration of spent accumulator acid could be an alternative process for crystallization, neutralisation and disposal. Therefore, for the first time in a study of the possibilities of electrochemical removal of antimony and accumulator acid regeneration on a laboratory scale, two synthetic and several real systems containing sulfuric acid of concentrations ranging between 28% and 36%, and antimony species were tested. Discontinuous electrochemical reactors with anion exchange membranes were successfully used in these experiments, which were conducted at a temperature of 35°C. Removal of antimony using cells that were not divided by a separator, however, was not possible. In selected experiments, by varying the electrode material, type of electrolyte, and cell current, the concentration of antimony could be reduced from the range of 5ppm to 0.15ppm. This resulted in current efficiencies between 0.00002% and 0.001%, and in specific electroenergy demands between 100WhL -1 and 2000WhL -1. In other experiments on substances with antimony contents up to 3500mgL -1, the current efficiencies obtained were more than a thousandfold higher. In contrast to the formally high relative energy consumption parameters absolute demand parameters are relatively small and favour the electrochemical method in small scale application. Besides plate electrodes, 3D-cathodes were used. Copper- and graphite cathodes produced the best results. © 2011 Elsevier B.V.


Due to their high stability and outstanding oxidation power doped diamond materials belong to the most fascinating electrodes in applied electrochemistry. During the last years they have aroused interest in the field of disinfection. As typical for chemical and electrochemical disinfection processes, benefit of disinfection has to be opposed to disadvantages of byproduct formation. Predictions with respect to reaction results are difficult. Essential influence factors are the composition of treated water, electrode potential and hydrodynamic conditions near the electrode surface. In waters of low ionic strength containing chloride ions an enlarged risk for chlorate and Perchlorate formation can be observed. The paper presents own results and summarizes state of development in the field. Formulation of new test and certification routines is recommended.


The disclosure describes a method for performing a bandwidth test for communications from a first network station (20) to a second network station (21) of a communication network. Such bandwidth test is based on the so-called PRM model (in words probe rate model) in which iteratively a train of probe sample packets is transmitted from first station (20) to the second station (21) with a constant packet rate per iteration. The packet rate however is adapted to the available bandwidth on the data pipe per iteration. According to the disclosure the number of probe sample packets per train of probe sample packets is varied with the available bandwidth per iteration. This increases the accuracy of the test in particular in the range where a high data rate is available on the data pipe. Also a step decreasing factor (SDF) is applied with which the performance test is improved. Such step decreasing factor is dependent on the network jitter and further improves the performance of the test.
