Phosphorus (P), in the form of phosphate ion (Pi), is a vital element contributing in biomolecule structures, metabolic reactions, signaling pathways and energy transfer within the living cells. The objective of the present study was to assess the influence of fungal infection on Pi metabolism in compare to the effects of phosphate stress in Arabidopsis. Quantification of total P contents showe...

Concept Design and optimization of cell culture processes requires intensive studies based on “Design of experiments”-strategies. In academia teaching of DoE-concepts is often insufficient, as in most cases only simple culture strategies (batch) can be performed, as time and money are limited. More complex tasks such as feeding strategies for fed batch culture can be discussed theoretically onl...

A competitive (nonmetabolizable) inhibitor of glucose uptake, alpha-methylglucoside, was used to limit the growth of Escherichia coli. Cell division during such a nutritional shift-down was studied in batch cultures and with the "baby-machine" technique. Following a brief delay, the rate of division was maintained for 60 to 70 min in batch cultures and for an extended period in the baby machine...

AIM To compare the growth patterns of breast fed and formula fed Italian infants in the first 12 months of life using World Health Organisation (WHO) reference data. METHODS The growth patterns of 73 breast fed infants (36 male, 37 female) and 65 formula fed infants (35 male, 30 female) were compared. Solid foods were introduced with the same weaning schedules from the 5th month in both group...

this study evaluated the suitability of canola oil as a source of supplemental dietary lipid for rainbow trout. triplicate groups of the 30 fingerlings held under identical culture conditions were fed twice daily by iso-nitrogenous, iso-calorific and iso-lipidic diets for eight weeks. experimental diets consisted of 30.3% protein, 18.7 kjg-1 energy and 16.7% lipid from fish oil (fo), canola oil...

sesame oil cake (ssc) was bio-processed through solid state fermentation (ssf) under optimized conditions by a phytase-producing fish gut bacterium, bacillus subtilis subsp. subtilis (jx292128). ssf significantly reduced anti-nutritional factors (e.g., phytic acid, tannins and trypsin inhibitor) and crude fibre, while enhanced free amino acids, fatty acids and different minerals. phytase product...

in recent years the use of rotifers as live food for rearing fish larvae and crustacean is very important. in this study, the effect of two concentrations (2.5×106, and 5×106 cell/ml-1) of two algae (powdered chlorella and nannochloropsis), on body and egg size of marine rotifer, brachionus plicatilis were investigated. rotifers were cultured in standard conditions in 500 ml plastic containers....
