The microbial diversity in waste dumps is considered to be high. Generally, ca. 99% of bacterial species remain unculturable in standard media. This research was focused to modify Nutrient Agar (NA) mimicking the natural substrate where bacteria actu

Elymus sibiricus is a highly valuable perennial forage that is widely planted in the Qinghai-Tibet Plateau (QTP) region. However, E. sibiricus artificial grasslands have a short utilization lifespan, and reach the highest yield in the 2nd and 3rd yea

Rationale Stable isotope approaches are increasingly applied to better understand the cycling of inorganic nitrogen (N-i) forms, key limiting nutrients in terrestrial and aquatic ecosystems. A systematic comparison of the accuracy and precision of th
