To evaluate the fermentation properties and bacterial community composition of mulberry leaves when ensiled with smooth bromegrass, effects Lactobacillus plantarum inoculation on mixed silage were bromegrass at ratios 100:0, 90:10, 80:20, 70:30 60:40, for 60 d without L. inoculant. The results showed that sole failed to achieve optimum quality. Silage a leaf ratio 80% performed better quality c...

Survival of Rhizobium trifolii on white clover seed before sowing is adversely affected by both drying and a water-soluble toxin which di f fuses f rom the seed coat dur ing the inocula t ion process . Survival of rhizobia is increased by removal of the toxin by seed washing or the suppress ion of i t s inhib i tory ef fec t by t rea tment of seed wi th phenol ic adsorbents . Surv iva l o f rh ...

Seventy-four Shiga toxin-producing Escherichia coli (STEC) isolates belonging to the serotype O91:H21 were isolated from 1,643 asymptomatic human carriers in a STEC outbreak at Gwangju in Korea. Although the isolates did not cause any symptoms, all of them produced Shiga toxins 1 (Stx1) and 2 (Stx2). In order to determine why these strains cause no symptoms, we explored the differences in virul...

The study of fungal-bacterial interactions in soils is not only interesting from a basic point of view but has also yielded findings of societal and economical relevance, such as in the application of biological controls of plant diseases. This study evaluated the effect of Tsukamurella paurometabola C 924, a bacterium with nematocidal action isolated from banana rhizosphere, as single inoculan...

the chemical composition, in situ ruminal degradability coefficients of dry matter (dm), and nutrient digestibility in sheep were evaluated for corn silage (cs) treated (fresh weight basis) with different levels of a commercial bacterial inoculant (i) as follows: (1) untreated cs (control); (2) cs + i at half of the recommended level; (3) cs + i at the recommended level (3  1010 colony forming...

The improvement of the fermentation quality of rice straw silage by application of lactic acid bacteria (LAB) and glucose was investigated in this study. Sixteen rice varieties were harvested at the maturity stage and the rice straw was ensiled with LAB inoculant (1×10 cfu/g of fresh weight) and glucose (2% of fresh weight). Inoculation with LAB improved the fermentation as reflected in reducti...

introduction ensiling is one of the common preserving methods for forage or other organic materials. in this method, organic matters were preserved by proving an aerobic condition and then by reducing the ph with increasing acids production (mainly lactic acid). some circumstances like enough soluble carbohydrates, low buffering capacity and appropriate dry matter concentration are needed in en...

Seed inoculation with plant growth promoting rhizobacteria (PGPR) is an ideal tool to supply the soil with a high density of beneficial microorganisms. However, maintaining viable microorganisms is a major problem during seed treatment and storage. In this work, an evaluation was made of the effect of bacterial immobilization in nanofibers on the stability (viability and maintenance of benefici...
