Je disais que certaines bacteries étaient produites par les bacteries, notamment la B12 ca j'en suis sure,
Mais beaucoup d'autres vitamines sont présentes directement dans les fruits, les légumes, les noix, et les graines...
Malheureusement les mélanges de graines utilisés pour l'alimentation des psittacidés sont déficients en plus de 12 constituants, dont la vitamine A et le Calcium... et trop riches en gras...
Le but lorsqu'on fait germer des graines, c'est de faire changer la composition des graines grace au processus de germination : la quantité de graisses diminue, celles en proteines et en vitamines augmentent...
Le but n'est pas de multiplier les bacteries et les champignons autour... (surtout qu'ils sont potentiellement dangereux)
Tiens voila d'autres resumés d'articles en anglais sur les graines germées, toujours en anglais pour les courageux dsl

The practice of sprouting is widely used to improve the nutritional value of grain seeds. Several nutritive factors such as vitamin concentrations and bioavailability of trace elements and minerals increase during germination. The objective of this work was to study the enrichment of various essential trace elements during germination of wheat (Triticum aestivum), buckwheat (Fagopyrum esculentum), and quinoa (Chenopodium quinoa) seeds in order to improve their nutritional role as a source of bioavailable trace elements. Seeds were sprouted either in distilled- or tap-water and in five different electrolyte solutions to investigate the concentration-dependent uptake. The time-dependence was investigated by analyzing aliquots of the sprouts after certain germination periods. Samples were analyzed after freeze drying for their Li, V, Cr, Fe, Mn, Co, Cu, Zn, Sr, Mo, As and Se concentrations with inductively-coupled plasma mass-spectrometry (ICP-MS). As a control for possible changes in the biochemical metabolism of the sprouts, the biosynthesis of vitamin C was also determined by using reversed-phase ion-pair HPLC. It was shown that quinoa was the most resistant to the applied electrolyte solutions and had the highest uptake rates for almost all elements, followed by buckwheat and wheat. Greatest increases were observed for Co, Sr, and Li. No significant changes in vitamin C biosynthesis were observed between sprouts grown in different electrolyte solutions. The time-dependent uptake for most elements was characterized by a significant absorption during soaking of the seeds, followed by a lag phase during the first day of germination and an increased uptake during the second and third day. Se and As showed distinctly different uptake behaviors.
Nutritional improvement of cereals by sprouting.

Cereal grains form a major source of dietary nutrients for all people, particularly those in the developing countries. However, the nutritional quality of cereal grains and sensory properties of their products are inferior due to lower protein content, deficiency of certain essential amino acids, lower protein and starch availabilities, presence of certain antinutrients, and the coarse nature of the grains. The consumption of sprouted cereals is becoming popular in various parts of the world. Sprouting of grains for a limited period causes increased activities of hydrolytic enzymes, improvement in the contents of certain essential amino acids, total sugars, and B-group vitamins, and a decrease in dry matter, starch, and antinutrients. The digestibilities of storage proteins and starch are improved due to their partial hydrolysis during sprouting. The magnitude of the nutritional improvement is, however, influenced by the type of cereal, seed quality, sprouting conditions, and it is not large enough to account for in feeding experiments with higher animals. In this review, the available literature concerning the nutritional improvement of cereals by sprouting and utilization of sprouted cereals in traditional and processed foods has been compiled and is critically reviewed.
Cereal sprouts: composition, nutritive value, food applications.
Lorenz K.
The practice of sprouting of cereal grains has become popular in the western world. Sprouted grains are thought of as having exceptional nutritive value. Sprouting is easy and can be done without sophisticated equipment. Untreated seeds of good quality and high germination percentage are placed in an environment of adequate water, a desirable temperature, and a certain composition of gases in the atmosphere for several days for sprouting. The sprouts can be kept for a few days to over a week under refrigeration. They can be used in many different foods including breakfast items, salads, soups, casseroles, pasta, and baked products. Sprouting of grains causes increased enzyme activity, a loss of total dry matter, an increase in total protein, a change in amino acid composition, a decrease in starch, increases in sugars, a slight increase in crude fat and crude fiber, and slightly higher amounts of certain vitamins and minerals. Most of the increases in nutrients are not true increases, however. They simply reflect the loss of dry matter, mainly in the form of carbohydrates, due to respiration during sprouting. As total carbohydrates decreases, the percentage of other nutrients increases. There are no nutritional evaluations of cereal sprouts in humans. Animal studies with cattle, pigs, chickens, and rats have failed to show a superior nutritive value of sprouted grains over ungerminated grains. Studies with humans are not likely to produce more encouraging results.
