“…The serial dilution technique was used to the isolation of fungi from the soil (Kutateladze et al, 2016). Five grams of the soil samples were mixed with a solution 95ml of 1% peptone water (Choudhary & Jain, 2012, Mohanasrinivasan et al, 2012 with some modification.…”

Crustacean shells constitute the traditional and current commercial source of chitin. Conversely, the control of fungal fermentation processes to produce quality chitin makes fungal mycelia an attractive alternative source. Our study examined the production of chitin from mycelia of different fungal isolatesrecovered from soil samples collected from different places in El-Beheira Governorate, Egypt, during 2021.

“…Such representatives of this micromycetes group are associated with the chemical composite of the substrate and are actively involved in the breakdown of the easily degradable compounds. The micromycetes release complex enzymes that facilitate the breakdown of more resistant compounds that are not easily susceptible to the initial degrading microbial actions [39][40][41].…”

Soil microorganism diversity has a close relation with soil function, and the changes in the composition of the soil microbial population can directly affect it. The aim of this study was to identify the bacterial community composition and determine the main soil chemical and physical properties formed by the different tillage systems. In the experiment, we analyzed the combination of three tillage systems and four organic fertilizers. Soil samples were taken from the two layers of the soil profile: the upper 0–10 cm and the lower 10–20 cm. The composition and diversity of soil bacterial communities were assessed by the sequencing of 16S rRNA genes. Results revealed that the highest biodiversity was found in the soil with shallow ploughless tillage and enriched with farmyard manure. Actinobacteria and Proteobacteria were the dominant bacterial species across all treatments. Their total abundance varied between 26% and 36% in the different analyzed agroecosystems. For the Dystric Bathygleyic Glossic Retisol, shallow ploughless tillage is the most suitable tillage system, as it creates favorable conditions for the accumulation of organic carbon in the soil under the Western Lithuania climate conditions.

“…They are also heterotrophic in nature and absorb nutrients from host plants by the help of specialized hyphae called the mycelium (Raaijmakers et al, 341-361) [26] . Some the examples of the pathogenic plant fungi inhabiting the soil are Fusariun oxysporum, Verticillium dahlia, Pythium aphanidermatum, Colletotrichum lindemuthianum, Rhizoctonia solani, Sclerotium rolfsii and Trichoderma species (Kutateladze, 227-232) [16] . Nematode are free living worm like soil organisms.…”

Plants are the sole producers that support all the trophic levels and sustain life on earth. In their growth and development, plants interact with both biotic and abiotic factors. The major biotic factors are the below ground microbes though there also above grown microbes and other herbivores. The abiotic factors are mainly the soil nutrients, soil temperature, moisture and light intensity. This paper therefore aimed at reviewing the various interactions within the soil rhizosphere especially between the plant roots interaction with soil microbes and how they are affected by the soil nutrient availability. The review focussed on identifying the major soil microbes in the soil rhizosphere, interaction of the plant roots with these microbes and how the interactions bring about nutrient cycling as well as dynamics in the trophic levels. From the review it came out clearly that plants interact with both pathogenic and non-pathogenic microbes resulting to varied results. Symbiotic relationship among plant roots and nitrogen fixing bacteria and mycorrhizal fungi results in improved plant growth and yields while interaction with pathogenic soil microbes resulted in disease development and reduced yield. Plants react to soil microbes by producing defensive secondary metabolites like phenolics. From the interaction some of the pathogenic microbes have developed mechanisms of evading the effects of plant defensive compounds by modifying them into forms that are less toxic. The review also shows that plant microbe interaction affects nutrient cycling and is also affected by the nutrients availability. The tripartite interaction of soil microbes, soil abiotic factors and plant root affects the general trophic levels in almost the entire ecosystems.
