The method is described for the rapid and objective estimation of the amount of carbon in the living, non-resting microbial biomass of soils. The method, which is based on the initial respiratory response of microbial population to amendment with an excess of a carbon and energy source, was quantified using an expanded version of Jenkinsons technique. The simultaneous application of the two methods to 50 soil samples showed a highly significant correlation (r = 0.96) between both. From this correlation it could be deduced that at 22C, a substrate-induced maximal respiratory rate of 1 ml CO2.h-1 corresponds to c.40 mg microbial biomass C. Evidence supporting these results was obtained from pure culture studies. The various soil types investigated were collected from agricultural as well as forest sites and they contained between 15 and 240 mg microbial C.100 g dry soil-1. The respiratory method provides reproducible estimates of biomass size whithin 1-3 h after soil amendment. It can be combined whithout difficulty with a selective inhibition method for determination of bacterial and fungal contributions soil metabolism. |

Goat milk, in addition to its nutritional characteristics, has functional properties and health-promoting benefits due to its content of biologically active constituents, especially peptides derived from its proteins, oligosaccharides, short and medium chain fatty acids and phospholipids. Among the several beneficial effects to human health, these compounds stand out for their role in preventing chronic diseases, especially cardiovascular diseases, most of them due to their antioxidant capacity, and in maintaining gastrointestinal health. Together with these goat milk molecules, calcium, one of the most important cell signalling components, has also demonstrated potential to prevent obesity and its associated risk factors. Several strategies have been investigated to enhance the health benefits of goat milk, with particular focus on increasing the levels of its bioactive constituents and minerals, enhancing the functionality of goat dairy products. The main functional properties of goat milk and the main improvement strategies are discussed in this review. |
