Objectives of this research were to characterize three genera of bacteria isolated from three of crop rhizosphere, and to measure the ability of the antagonistic bacteria in suppressing lincat disease caused by Ralstonia solanacearum and Meloidogyne incognita. The research showed that the sixth bacteria were able to utilize some carbon and nitrogen compounds, degrade macromolecules, grew at different temperatures and salt contents, and grew at medium with chitin and pectin.  The bacteria isolated from pepper rhizosphere (Pf51, Ba4, Ba22), groundnut (Pf83), and eggplant (S4 dan S7) was included to fluorescent pseudomonads (Pf51 and Pf 83), Bacillus spp. (Ba4 and Ba22), and Streptomyces spp. (S4 and S7).  The sixth bacteria having the ability in antagonist.  The bacteria isolate having the best ability in suppressing Ralstonia solanacearum and Meloidogyne incognita was Streptomyces spp. (S4). The bacteria isolate having the best ability in suppresssing R. solanacearum by antibiosis and the inhibition mechanism by bacteriostatic was S4

Endophytes are increasingly investigated as biocontrol agents for agricultural production. The identification of new endophytes with high effectiveness against plant disease is very important. A total of 362 strains of endophytes, including fungi, bacteria, and actinomycete, were isolated from alfalfa (Medicago sativa L.) collected in Hebei, Inner Mongolia and Ningxia provinces of China. The three strains of endophytic bacteria (NA NX51R-5, NA NX90R-8, and NA NM1S-1) with strong biocontrol capability with >50% effectiveness were screened against the common alfalfa root rot pathogen Fusarium oxysporum F. sp. medicaginis in alfalfa seedling germination experiments on MS medium and pot experiments. Using phylogenetic analysis, the isolates of NA NM1S-1 and NA NX51R-5 were identified as Bacillus spp. by 16S rDNA, while NA NX90R-8 was found to be Pseudomonas sp.

A total of 91 isolates of probable antagonistic bacteria of potato soft rot bacteriumErwinia carotovorasubsp.carotovora(Ecc) were extracted from rhizospheres and endophytes of various crop plants, different soil varieties, and atmospheres in the potato farming areas of Bangladesh. Antibacterial activity of the isolated probable antagonistic bacteria was testedin vitroagainst the previously identified most common and most virulent soft rot causing bacterial strain Ecc P-138. Only two isolates E-45 and E-65 significantly inhibited thein vitrogrowth of Ecc P-138. Physiological, biochemical, and carbon source utilization tests identified isolate E-65 as a member of the genusBacillusand the isolate E-45 asLactobacillussp. The stronger antagonistic activity against Ecc P-138 was found in E-65in vitroscreening and storage potatoes. E-65 reduced the soft rot infection to 22-week storage potatoes of different varieties by 32.5–62.5% in model experiment, demonstrating its strong potential to be used as an effective biological control agent for the major pectolytic bacteria Ecc. The highest (62.5%) antagonistic effect of E-65 was observed in the Granola and the lowest (32.7%) of that was found in the Cardinal varieties of the Bangladeshi potatoes. The findings suggest that isolate E-65 could be exploited as a biocontrol agent for potato tubers.
