Abstract

This paper examines rhizoremediation as a sustainable and environmentally acceptable remediation technique in response to the growing problem of petroleum hydrocarbon pollution in soils. Brachiaria ramosa, a tropical grass species that may be useful in contaminated settings, is the main emphasis. A critical analysis of the literature on plant growth-promoting rhizobacteria (PGPR), microbial consortia involved in hydrocarbon breakdown, and rhizosphere-mediated degradation is conducted. There is a thorough discussion of important mechanisms such as root exudation, microbial stimulation, increased hydrocarbon bioavailability, and interactions between plants and microbes. The physicochemical characteristics of the soil, the surrounding environment, and the dynamics of the microbial population are all factors that affect the effectiveness of remediation. Despite the paucity of direct experimental evidence specific to B. ramosa, established rhizoremediation principles and insights from related species point to its potential use. This review identifies existing knowledge gaps and stresses the necessity of field-scale research and controlled experimental validation. All things considered, combining B. ramosa with efficient microbial systems is a viable approach to the long-term cleanup of hydrocarbon-contaminated soils.

Keywords: Rhizoremediation, Brachiaria Ramosa, petroleum hydrocarbons, plant growth-promoting rhizobacteria (PGPR), microbial consortia, soil remediation, sustainable agriculture, environmental restoration
