Influence of some Bio-amendments usage on quality of spent wasts of Oyster mushroom (Pleurotus ostreatus(Jacq.)Fr.)


This study was condacted to evaluate the influence of some bacrial inoculated usage as( Azotobacter spp,Streptomyces spp and Pseudomonas spp) on the remining substrate of Oyster mushroom ( Pleurotus ostreatus (jacq).fr.) after crop cycle completed and determining usage it in animal feeding or as an organic fertilizer .البحث مستل من رسالة ماجستير للباحث الرابعThe results indicated that the best protein contents after crop cycle completed was in mixture 2,mixture3and sunflower substrates inoculated by Az. 9.9%,9.9%and 9.2% respectively , this increased in protein contents causes an enhensment C/N ratio in all substrates ,the best one was sunflower waste substracte inoculated by Az. 1:13 while in wheat straw , corn cobs , mixture 1,2 and 3 substreates were 1:14.8, 1:14.6, 1:15.1, 1:13.1 and 1:15.1 respectivly when were befor P.ostreatus cultivated. 1:44, 1:39, 1:36, 1:37, 1:35 and 1:32.5 respectivly. On other hand bacterial amendements usage causes to reduced phenolic substances percentage on spent wastes which was 0.119% on wheat straw inoculated by Az. or St. , where highly phenolic substances percentage 0.135% and 0.131% obtaind on mixture inoculated by Az. and St. , Microbiol densty was enhancement in all substrates which were used in this study ,this characetr led to used it agood organic fertilizer .
