Testing the ability of Lactobacillus spp for Organic material degradation

Abstract

welve isolates of Lactobacillus sp from twenty four samples were collected from different sources:- four samples from soil (S), twenty samples from different foods includs Vegetable four (V), fruit tow (F), spoilage cooking food tow (F0), Dairy product like Youghart four (Y), cheese four (Ch), Cream one (C) and one sample from fish (Fm1), sheep meat( Shm1), Chicken meat (Chm1). These samples were tested shaply, microscopically, biochemicaly and their ability to grow and analyzed different organic material such material like tannic acid, phenol, chloroform, heptan with different concentrations(6,8,10)% by using different type of media likeN.A, MRSA, BHIA.The Lactobacillus spp organic material degradation ability were tested and shown the following results, isolates LY3, LCh1, LV1, LV, LF1, LF01were analyzed intermediate and minimum concentrations while two isolates LFM1, LChm1were able to analyzed of tannic acid when found with minimum concentration. The best media MRSA in grow and analyzed of tannic acid. The isolates LY2, LCh2, LC1, LF1, LF01showen ability to grow in all media when phenol were used, while the isolates LY2, LCh2, LC1are the best in analyzed from all isolates , media MRSA is the best media for analyzed The chloroform were used as substrate to testing ability of bacteria to grow the isolates LY2, LY3, Lch2, Lc1, LV2, LFm, LF1 are the best for grow, while isolates LY2, LY3, LChm showen best ability to analyzed. The media nutrient agar is the best. when heptan are used the isolates LY2, LY3, Lch2, LV2, LF1, LChm1 give best grow in 3 concentrations, while isolates LY1, LV2, LF1, Lf01 give best analyzed.The media nutrient agar is the best.
