The recommended cultivars for top quality wines Riesling in the vineyards of Grocka is in full crop. It was grafted on Kober 5 BB stock and planted on the soil type cambysoil. The content of total nitrogen is 0.1-0.15%. Supply of easily available potassium varies between 12.3-15 mg/100g a.d.s.2, i.e. phosphorus 0.4-3.6 mg/100g a.d.s. in layer up to 40 cm. Microbiological fertilizer was used in the study - biological preparation prepared with mixed natural populations Azotobacter chroococcum, Bacillus megaterium and Bacillus circulons. The space in row is idle land and the space between rows was sown each year (March-April) with a mixture of field pea and barley and ploughed in the inflorescence phase of legumes. Grape yield varied between 8772-6804 kg/ha. Microbiological fertilizer with Azotobacter had the highest yield and the control treatment had the lowest yield, where only grass mixture was sown. Extremely dry climatic conditions in the trial period caused the grape yield in cv. Riesling to be extremely low. In combination of fertilizers Bacillus megaterium + Bacillus circulons wine with the most ethanol, extracts and polyphenols was obtained. The wine obtained from the control treatment had a typical taste
Zastita Materijala 57 (3) 455-459 (2016) Raman spektroskopija i determinacija zemljišnih kvasaca IZVOD U ovom radu su Raman spektroskopijom ispitivana dva izolata kvasaca iz roda Candida. Izolacija kvasaca je izvršena iz zemljišta uzetog iz gradskog parka u Tivtu (Crna Gora) i sa oglednog dobra Radmilovac (Poljoprivredni fakultet, Beograd, Srbija), metodom nakupljanja. Dobijene čiste kulture kvasaca identifikovane su primenom API AUX 20C sistema (bioMerieux-Vitek). Konstatovano je prisustvo vrsta Candida guilliermondii i Candida utilis. Analizirani su Raman spektri koji potiču od lipida, amida, proteina, ugljenih hidrata, aromatičnih aminokiselina i nukleotidnih baza, u širokoj oblasti talasnih brojeva, od 500 do 3200 cm-1. Utvrđeno je da su kod kvasca Candida guilliermondii pikovi koji odgovaraju frakciji lipida bitno izraženiji nego kod Candida utilis, što može predstavljati specifičan odgovor date vrste kvasca na stres.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
