Environmental interactions between protists and bacterial communities in hydrocarbon degradation.

Reclamation of petroleum-polluted environments is a key issue for today and in the future, as our reliance on oil will persist for decades. An eco-friendly solution is to use microbes that play a role in petroleum-hydrocarbon degradation. However, as hydrocarbon degradation involves a multi-step process involving different functional groups, focusing only on finding efficient bacterial species will not be the complete solution.

Siderophore-producing bacteria mitigate cobalt stress in black gram (Vigna mungo L.), and the mitigation strategies are associated with iron concentration.

Cobalt (Co) is considered an essential element in agriculture as it is an important constituent of vitamin B. Due to natural and anthropogenic factors, heavy metals, especially Co, accumulate in agricultural fields, but their high exposure produces ramifications in crop plants, thereby reducing crop yield and biomass. Excessive Co in plants causes oxidative stress, and as the stress progresses, Co competes with iron (Fe) thereby decreasing chlorophyll content and resulting in Fe deficiency in plants.

Methylobacterium spp. mitigation of UV stress in mung bean (Vigna radiata L.).

Methylotrophs are a diverse group of bacteria that abundantly colonize the phyllosphere and have great potential to withstand UV irradiation because of their pigmented nature and ability to promote plant growth through various mechanisms. The present study investigated the effects of UVB radiation on plant growth-promoting (PGP) properties of methylotrophic bacteria and the growth of Vigna radiata L. A total of 55 methylotrophic bacteria were isolated from desert plants, and 15 methylotrophs were resistant to UVB radiation for 4 h.

Encapsulation of Pseudomonas aeruginosa strain KBN12 decolourizes and bioremediates brilliant blue dye mediated toxicity in mung bean (Vigna radiata L.).

Aim: The aim of this study was to explore the decolourization and bioremediation ability of non-encapsulated and encapsulated Pseudomonas aeruginosa (strain KBN 12) against the azo dye brilliant blue (BB).

Methods And Results: Six efficient BB dye-decolourizing bacteria were isolated from textile dye effluent. The most efficient free cells of P.

Microbial volatile compounds (MVCs): an eco-friendly tool to manage abiotic stress in plants.

Microbial volatile compounds (MVCs) are produced during the metabolism of microorganisms, are widely distributed in nature, and have significant applications in various fields. To date, several MVCs have been identified. Microbial groups such as bacteria and fungi release many organic and inorganic volatile compounds.
