Successful rabbit production relies heavily on the use of adequate practices that enhance specific aspects reproduction, such as mating, ovulation and lactation. Regardless type unit or strain rabbits used, these processes rely a complex chain neuroendocrine steps include particular hormones, peripheral stimuli activation discrete brain regions. Such is case, for instance, reflex ovulation, whi...

AIM To study the response of the bacterial community to bioremediation of a soil with an aged contamination of crude oil. METHODS AND RESULTS The bacterial community in laboratory soil columns during a 72-day biostimulation treatment was followed by analysing the number of total cultivable hydrocarbon-degrading bacteria, soil respiratory activity and the 16S-23S rDNA internal transcribed spac...

The surge of interest in bioenergy has been marked with increasing efforts in research and development to identify new sources of biomass and to incorporate cutting-edge biotechnology to improve efficiency and increase yields. It is evident that various microorganisms will play an integral role in the development of this newly emerging industry, such as yeast for ethanol and Escherichia coli fo...

Sediment containing a mixture of iron (Fe)-phases, including Fe-oxides (mostly Al-goethite) and Fe-silicates (illites and vermiculite) was bioreduced in a long-term flow through column experiment followed by re-oxidation with dissolved oxygen. The objective of this study was (a) to determine the nature of the re-oxidized Fe(III), and (b) to determine how redox cycling of Fe would affect subsequ...
