“…It is known that B. subtilis species are heterogeneous both phenotypically and genotypically [27]. High genetic heterogeneity of different Bacillus species [5] [28] particularly B. subtilis allows to suggest that search and identification of new strains from different sources may expand the number of practically important strains and to improve our understanding of mechanisms involved in antagonistic interactions.…”

Bacillus strains isolated from the rhizosphere soil of potato roots were evaluated for the potential antagonistic activity against fungal pathogens in vitro and in vivo. Two bacterial isolates were identified as new Bacillus subtilis strains by 16S rRNA and GyrB gene sequencing and were designated GM2 and GM5, respectively. Strains were characterized by their ability to inhibit growth of a number of phytopathogenic fungi. It was shown that GM5 strain inhibited growth of phytopathogenic fungi more effectively than GM2 strain. Both strains were capable of producing a number of hydrolytic enzymes as well as antimicrobial metabolites (ammonia and HCN). In addition, GM2 strain also produced siderophores. Four genes encoding antimicrobial peptides were identified in the genome of GM2 strain: ituC, bmyB, bacA and srfA. Genome of GM5 contained two genes encoding for antimicrobial peptides, srfA and fenD. Purified lipopeptide fraction from GM5 but not from GM2 strain was able to control Fusarium solani spread in the plate assay. Furthermore, Bacillus subtilis strain GM2 promoted growth of wheat but only GM5 strain was able to protect wheat seedlings from Fusarium oxysporum infection.

In the present work marine sediment samples were collected from Thengapattanam estuary on the south west coast of India for the isolation and screening of bacteria for biocidal potency. The density of the bacterial load in the sediment samples was ranged from 5.43x10 4 to 2.8x10 6 CFU/g. Screening of bacterial isolates for antagonistic activity revealed that the isolate MS21 had the highest zone of clearance among against all the 10 plant fungal pathogens tested. Among 10 fungal pathogens, the highest antagonistic activity was observed against Gleosporium gleosporioide (36mm) and the lowest against Colletotrichum lamella (11mm). The potential isolate was identified as Bacillus subtilis using biochemical methods and it was designated as Bacillus subtilis MS21. Effect of various physicochemical parameters on growth of B. subtilis MS21 showed that 36 hrs of incubation period, 150 rpm agitation, pH-8.0, temperature-35 o C, salinity-1.0%, 2% sucrose as carbon source and 1% beef extract as nitrogen source were found to be the ideal conditions for maximum growth. Maximum growth of 1.92 OD was observed in mass scale culture with the optimized ideal conditions in the shake flask.

“…Some strains of Bacillus produce cytokinins, thus acting as plant growth-promoting bacteria (2). Other strains inhibit the pathogenic fungus Fusarium graminearum in durum wheat (3). From the agronomic point of view, wheat is a well-characterized crop, with a worldwide economic relevance, whose associated bacteria could influence plant growth (4).…”

bThis study aimed at assessing the dynamics of lactic acid bacteria and other Firmicutes associated with durum wheat organs and processed products. 16S rRNA gene-based high-throughput sequencing showed that Lactobacillus, Streptococcus, Enterococcus, and Lactococcus were the main epiphytic and endophytic genera among lactic acid bacteria. Bacillus, Exiguobacterium, Paenibacillus, and Staphylococcus completed the picture of the core genus microbiome. The relative abundance of each lactic acid bacterium genus was affected by cultivars, phenological stages, other Firmicutes genera, environmental temperature, and water activity (a w ) of plant organs. Lactobacilli, showing the highest sensitivity to a w , markedly decreased during milk development (Odisseo) and physiological maturity (Saragolla). At these stages, Lactobacillus was mainly replaced by Streptococcus, Lactococcus, and Enterococcus. However, a key sourdough species, Lactobacillus plantarum, was associated with plant organs during the life cycle of Odisseo and Saragolla wheat. The composition of the sourdough microbiota and the overall quality of leavened baked goods are also determined throughout the phenological stages of wheat cultivation, with variations depending on environmental and agronomic factors.
