“…The selected isolates could be 10 grouped into four genera, i.e., Bacillus (4 strains), Klebsiella (1 strain), Pseudomonas (2 strains) and Xanthomonas (1 strain). Similarly, other researchers have done reports about the isolation of endophytic bacteria from maize, 27 carrots, 28 common bean, 29,30 and sugar beet. 31 There was significant diversity in the types of endophytes bacteria, both genotypic and phenotypic.…”

In order to appraise the bacterial endophyte communities that help resist disease in potato tuber, the separation, the population density, biodiversity and the antagonistic activity of endophytic bacteria, from the tuber peel of potato cultivars (Fontan90, Agria, Sante’a and Jeli89), were examined in the Fars province in Iran. In this study, the bacterial endophyte Colony Forming Units (CFU) were counted based on the most suitable dilution in petri dishes and expressed per g of wet weight of tuber tissue. The presence of bacteria was found mostly in the outer layer. A wide variety of endophyte species biodiversity was in Agria cultivar. To estimate the antagonistic effect of potato associated endophytic bacteria, 115 bacterial isolates were evaluated by dual culture method against main soil-borne potato pathogens Fusarium oxysporum, Rhizoctonia solani, Verticillium dahliae, Streptomyces scabies and Ralstonia solanacearum. Endophyte strains were identified based on physiological, morphological and chemical characteristics and the 16S rRNA gene sequence analysis. The highest degree of the inhibitory activity in all layers of potato cultivars was related to Bacillus subtilis, Bacillus mojavensis and Klebsiella variicola. Antagonistic activity of endophytic bacteria against the pathogens was significantly higher (p<0.01) in the examined strains from the outermost layer of tuber peel and decreased progressively toward the center of the tuber. In this research, Klebsiella variicola was reported as endophyte bacteria in the four commercial potatocultivars mentioned above, for the first time.

“…The isolates were incubated at 30ºC for three days and then flooded with Lugol's iodine solution for clear zone development. (Nan et al, 2019) Hydrogen sulphide production SIM agar medium tubes were stab inoculated by test isolates and incubated for 24-48 hours at 37ºC. Tubes were then observed for the presence of black coloration along the line of stab inoculation indicating hydrogen sulphide production (Clarke et al, 1953).…”

Bacterial antagonist, Bacillus spp. cultures were isolated from different places of Kuttanad region. Three effective endophytic Bacillus strains viz., B 15, B 17 and B 33 were tested in the separate field experiments against sheath blight and bacterial blight diseases of rice during Kharif 2017, Rabi 2018-19, Kharif 2019 and Kharif 2020. In the field study, the Bacillus cultures were treated as standard bioagent application methods of seed (10 g/kg), soil (1 kg/acre) and foliar (20 g/litre of water) spraying against the major diseases in rice. The rice associated native Bacillus cultures B 15, B 17 and B 33 were found equally effective for the sheath blight and bacterial blight diseases management. All the three native Bacillus species can be used as potential biopesticides against rice sheath blight and bacterial diseases in Kuttanad region.
