Microbial Biofilm for Soil Health, Plant Growth, and Productivity under Multi Stress. A Review

Abstract

The increase in temperature due to global warming leads to a rise in abiotic and biotic stresses for plants. Biofilms can aid plants in overcoming multiple environmental stresses. The purpose of this article is to examine biofilm technology, mechanisms, and efficacy in assisting plant performance under multiple stresses. The methodology used to write this literature review is based on references that can be accessed online via Science Direct, Google Scholar, scopus.com, and other sources. The results demonstrated that interaction between plants and microorganisms in the rhizospheres could aid plants in coping with environmental stress caused by the formation of a biofilm on the root surface by a consortium of microorganisms in the rhizosphere. Biofilm provides numerous benefits for plants, including improved soil health, protection from pathogens, promotion of plant growth, assistance with nutrient absorption, decreased use of inorganic fertilizer, and increased environmental tolerance. Biofilm technology is a promising soil management strategy for assisting plant adaptation to environmental stresses, enhancing plant growth and productivity, and promoting soil health.

Flood vulnerability assessment trough overlay-scoring data method based on Geographical Information System (GIS) in Giriwoyo, Wonogiri, Indonesia

“…High slope increases the water rate on the ground surface thereby minimizing flooding [26]. The land cover is dominated by forests [27]. Vegetation in forests can protect soil from erosion and optimize infiltration rates [28].…”

Phytohormone-Based Biostimulants as an Alternative Mitigating Strategy for Horticultural Plants Grown Under Adverse Multi-Stress Conditions: Common South African Stress Factors

“…Stress can be categorized as either biotic or abiotic, depending on the nature of the inducing factor. Biotic stress is caused by biological factors that affect plant development and productivity (Dewi et al, 2023). In addition, globally, around 20 to 40% of agricultural crop yield losses occur due to factors such as strong wind, radiation, mechanical damage, chemical treatment with heavy metals, herbivores, and infection by damaging host cells like fungi, bacteria, or viruses at different stages of plant growth (Al-Khayri et al, 2023).…”

Enhancing Melon Growth and Nutrient Uptake with Plant-Growth-Promoting Microorganisms from Cucumis melo

“…Melon has a highwater demand and needs nutrient balance for optimal plant growth and development [7]. The species' predilection for high-resource inputs, however, challenges sustainable cultivation [8,9], with intensive use of chemical inputs leading to soil microflora suppression, and environmental degradation [10][11][12].…”

“…The rhizosphere, a nexus of soil-root interactions, teems with microbial life, modulated by root exudates rich in organic nutrients [13,14]. Within this intricate ecosystem, microorganisms serve as crucial agents, augmenting nutrient accessibility, endowing resistance to pathogens, and regulating plant growth [11]. Notably, certain bacterial and fungal taxa, collectively termed plant growth-promoting microorganisms (PGPM), have garnered recognition for their contributions to enhancing agricultural productivity and fortifying crop resilience [15,16].…”
