Introduction The in situ method is used widely to determine ruminal degradability of feed CP and DM. It is an attractive alternative to in vivo methods because it is simple, inexpensive, and rapid. However, several factors influence in situ results, the most important of which is microbial contamination of feed residues after incubation in the rumen. Degradation of forage CP and DM is systemati...

The standard index of microbial air contamination (IMA) for the measurement of microbial air contamination in environments at risk is described. The method quantifies the microbial flow directly related to the contamination of surfaces coming from microbes that reach critical points by falling on to them. The index of microbial air contamination is based on the count of the microbial fallout on...

Drilling and handling of permanently frozen soil cores without microbial contamination is of concern because contamination e.g. from the active layer above may lead to incorrect interpretation of results in experiments investigating potential and actual microbial activity in these low microbial biomass environments. Here, we present an example of how microbial contamination from active layer so...

The success rate of embryo production critically depends on several factors. One of the pivotal factors is a technique used for the whole procedure of in vitro fertilization (IVF) and in vitro embryo culture (IVC) (1, 2). Besides the technique selected for IVF / in vitro embryo production (IVEP), there is an important consideration called IVF/IVEP culture dishes disin...
