From shake flasks to a bench‐scale bioreactor: scaling up exopolysaccharide production in fed‐batch cultivation of Ensifer meliloti SEMIA 135

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND This study investigates the production scale‐up of exopolysaccharide (EPS) by Ensifer meliloti SEMIA 135 from shake flasks to a 5 L bench‐scale fed‐batch bioreactor. Soybean molasses was the cost‐effective nutrient source. The primary aim was to improve conditions for maximizing EPS yield and minimizing production costs.

Control of the rhizobium–legume symbiosis by the plant nitrogen demand is tightly integrated at the whole plant level and requires inter-organ systemic signaling

Frontiers in Plant Science, 2023
Symbiotic nodules formed on legume roots with rhizobia fix atmospheric N2. Bacteria reduce N2 to NH4+ that is assimilated into amino acids by the plant. In return, the plant provides photosynthates to fuel the symbiotic nitrogen fixation.

A rhamnose-deficient lipopolysaccharide mutant of Rhizobium sp. IRBG74 is defective in root colonization and beneficial interactions with its flooding-tolerant hosts Sesbania cannabina and wetland rice.

Journal of Experimental Botany, 2016
Rhizobium sp. IRBG74 develops a classical nitrogen-fixing symbiosis with the aquatic legume Sesbania cannabina (Retz.). It also promotes the growth of wetland rice (Oryza sativa L.), but little is known about the rhizobial determinants important for ...

High Temperatures and Bacillus Inoculation Affect the Diversity of Bradyrhizobia in Cowpea Root Nodules

Journal of Basic Microbiology, EarlyView.
ABSTRACT Future climatic scenario predictions indicate a substantial temperature increase, reducing crop production worldwide and demanding the development of adaptations in agriculture. This study aimed to assess the impact of high temperatures and amendments with Bacillus on nodulating bradyrhizobia.

Assessing Liquid Inoculant Formulation of Biofertilizer (Sinorhizobium meliloti) on Growth, Yield, and Nitrogen Uptake of Lucerne (Medicago sativa)

Nitrogen, 2023
Lucerne is regarded as the best legume crop for forage to be cultivated in South Africa. It is commonly used to produce good quality hay. It also plays an important role in soil conservation, regeneration, and crop rotation systems as it supplies ...

Contribution to the HiStory Series in Plant Nutrition

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT After Justus von Liebig had largely recognized the necessity of nitrogen fertilization to achieve high yields from 1862 onwards, the question of why legumes are particularly beneficial for crop rotation remained unanswered. Schultz‐Lupitz (1831–1899), who convincingly proved the preceding crop effect of legumes for cereals as a subsequent crop

The Application of Rhizobium and Urea on Paraserianthes falcataria Seedling Growth

Jurnal Sylva Lestari, 2018
Paraserianthes falcataria is naturally had symbiosis with nitrogen-fixing bacteria (Rhizobium). Urea is fertilizer with high content of nitrogen (46%). The research aimed to study the effect of Rhizobium inoculation on P.

Rhizobium altiplani sp. nov., isolated from effective nodules on Mimosa pudica growing in untypically alkaline soil in central Brazil.

International Journal of Systematic and Evolutionary Microbiology, 2016
Root nodule bacteria were isolated from nodules on Mimosa pudica L. growing in neutral-alkaline soils from the Distrito Federal in central Brazil. The 16S rRNA gene sequence analysis of 10 strains placed them into the genus Rhizobium with the closest ...

Transfer of Virulence in Rhizobium trifolii [PDF]

Nature, 1961
So far, very few reports concerning transformations in Rhizobium have appeared. Krasilnikov1 reported as early as 1941 that non-infective strains turned infective when they were grown for several months in a filtrate of a highly infective strain. By ultrasonic treatment and with preparations of deoxyribonucleic acid (DNA) Balassa2,3 has obtained ...

Interdisciplinary approaches to enhance sensory properties and consumer acceptance in pulse crops

PLANTS, PEOPLE, PLANET, EarlyView.
Enhancing the flavor profile of pulse crops such as chickpea, dry pea, and lentil is essential for increasing human acceptance of plant‐based diets. Despite their nutritional value, undesirable sensory attributes of pulses, including off‐flavors and bitterness, reduce consumer acceptance.
