The main aims of our work were comparative studies of the phase state and structure of the lipid bilayer of the outer membrane (OM) of the cells of four free-living rhizobium strains and also of the influence of the composition of symbiotic pairs on the state and structure of the outer membrane of bacteroids (bacteroid membrane, BM) and PBM, that forms the symbiosomes inside the plant cell.
However, taking into consideration that iron stressed plants show fewer bacteroids present in the nodules, decreased amount of leghemoglobin and lower specific nitrogenase activity, and that possession of the ability to produce siderophore significantly increases the efficiency of the differentiated bacterium to fix nitrogen and induce an increase in plant growth.
This condition supported by the significance of tricarboxylic acid cycle regulatory events like PHB synthesis and alanine synthesis also depends on the overall need to stabilize the oxidation-reduction state of pyridine nucleotides with the total carbon and nitrogen pools in the bacteroids [15].
Most of the core genera were Firmicutes, except Prevotella and Bacteroides, which belong to Bacteroidetes.
Subsequently, IAA production enhanced the root length and provides larger surface area for more bacteroids attachment, leading to more nodulation.
Bacteroidetes include Bacteroids and Prevotella species.

Culture results were obtained in 36 patients, and the most frequent bacterial organisms cultured from the wounds were Escherichia coli (n:9, 25%), anaerobic Streptococcus species (n:4, 11.1%), Staphylococcus aureus (n:4, 11.1%), Enterobacter spp (n:2, 5.6%), Bacteroides (n:2, 5.6%), Pseudomonas aeruginosa (n:2, 5.6%), Proteus species (n:2, 5.6%), Clostridia species (n:2, 5.6%) and mixed microorganisms (Escherichia coli, Staphylococcus aureus, anaerobs, n:9, 25%).
In addition to N, molybdenum (Mo) also has a large effect on BNF because the main functions of Mo in the plant are related to N metabolism, specifically the nitrogenase enzyme system present in the bacteroids in nodules and the nitrate reductase enzyme system that is essential for plant N assimilation (Dechen & Nachtigall, 2007).
The principal organism seen in normal appendix, in acute appendicitis, and in perforated appendicitis are Escherichia Coli and Bacteroids fragilis.
