This research evaluated a bacterial strain, (S55), isolated from the soil for its bioflocculant production capabilities. The strain was identified through morphological and 16s rRNA gene sequencing. The optimization of culture conditions, using One-factor-at-a-time method, significantly enhanced bioflocculant production with glucose and urea. FTIR analysis showed the presence of hydroxyl, amine and carboxylate functional groups, with polysaccharides as predominant components. Scanning electron microscopy and X-ray diffraction confirmed the crystalline nature of the bioflocculant. The strain studied showed potential in treating household wastewater and was effective at removing dyes, suggesting alternatives for wastewater management.

The seed microbiota, a still underexplored component of plant-microbe interactions, plays a pivotal role in plant development and holds significant promise for advancing sustainable agriculture. By influencing essential processes such as germination, stress tolerance, nutrient acquisition and defence, seed-associated microbes offer unique advantages beyond those of soil- or rhizosphere-associated microbiomes. Notably, they are transmitted both vertically and horizontally; however, fundamental questions remain regarding their origin, ecological dynamics and functional roles across environments.

Caliciopsis pinea is the ascomycete plant pathogen that causes caliciopsis canker disease on North American Pinus strobus (eastern white pine). Infections result in downgrading of lumber due to canker formation and overall loss of vigor in P. strobus, which is a critical cover species throughout its native range.

A novel bacterial strain, SM-13 was isolated from the rhizospheric soil of Epipremnum aureum (Jade Pothos) sampled in Suwon, Republic of Korea. The isolate was Gram-stain-negative, aerobic, motile, rod-shaped, cream-coloured, oxidase- and catalase-positive. Strain SM-13 grew at the range of 15-37 °C (optimum, 25 °C), at pH 6.
