Soil microbiota

Ebook "Intestinal microorganisms of termites and other invertebrates" focuses on the microbes in gut systems of soil animals. It starts with a profound overview of the biology of soil invertebrates. A major part deals with the gut microbiota of termites, the best investigated gut system of invertebrates. Termites are important soil processors in tropical and subtropical regions.

Vermicompost contains beneficial bacteria, vermicompost is a finely divided peat-like material with high porosity, good ventilation, drainage, water-holding capacity, microorganism activity, Excellent nutritional status and buffering capacity thus provide the physiological properties required for soil fertility and plant growth. Worm manure enhances soil biodiversity by promoting entry and enhances plant growth directly by producing plant growth-regulating hormones and enzymes.

Soils are a key component of agricultural productivity, and soil microbiota determine the availability of many essential plant nutrients. Agricultural domestication of soils, that is, the conversion of previously uncultivated soils to a cultivated state, is frequently accompanied by intensive monoculture, especially in the developing world.

The bacterial communities in the soil samples were analyzed using the Illumina Miseq® platform. Statistical analysis of the microbiota between the control and flooded soil show that there is no statistical difference between the two (p > 0.05).

Extensive use of synthetic fertilizer to maximize the productivity often leads to depletion of essential soil nutrients, environmental degradation and adversely affects soil rhizosphere microbiota. The present study investigates the efficacy of Trichoderma and biochar co-application on tomato productivity, nutritional quality and soil health improvements under reduced N-P-K fertilizer application.

The influence of two factors - "broomrape" and "soil type" on quantities of seven trophic groups of soil microorganisms (Autochthonous; Oligotrophic; Actinomycetes; Microscopic fungi; Ammonifying; Assimilating mineral nitrogen; Aerobic nitrogen-fixing bacteria of the genus Azotobacter) were determined. Soil samples for microbiological analysis were taken from the rhizosphere zone of plants in sunflower crops from two soil types (Haplic Vertisols and Chromic Cambisols), in phenological phases of sunflower and of broomrape - "flowering".

The aim of this study was to isolate and identify environmental bacteria from various soils in areas where human activities influence the soil microbiota and might exert a strong positive pressure to resistance development and spreading. Our results revealed that environmental bacteria with high antibiotic resistant level. All the gram positive bacterial isolates showed resistant against Penicillin G and Ampicillin. Out of 27 gram negative bacterial isolates, 23 organisms showed ESBL positive based on phenotypic characterization.

Microorganisms play important roles in the recycling of agricultural wastes. Composting is the degradation of organic materials through the activities of diverse microorganisms. The compost generated by bioconversion of agro-residues offers several benefits such as enhanced soil fertility and soil health which can lead to increased agricultural productivity, improved soil biodiversity, reduced ecological risks and a healthier environment. This investigation examined the microbial community dynamics, loads and identification of microbiota at various stages of composting process.

Ureases, enzymes that catalyze urea hydrolysis, have received considerable attention for their impact on living organisms’ health and life quality. On the one hand, the persistence of urease activity in human and animal cells can be the cause of some diseases and pathogen infections. On the other hand, food production can be negatively affected by ureases of soil microbiota that, in turn, lead to losses of nitrogenous nutrients in fields supplemented with urea as fertilizer.

A plant’s microbiota has various implications for the plant’s health and performance; however, the roles of many microbial lineages, particularly Archaea, have not been explored in detail. In the present study, analysis of archaea-specific 16S rRNA gene fragments and shotgun-sequenced metagenomes was combined with visualization techniques to obtain the first insights into the archaeome of a common salad plant, arugula (Eruca sativa Mill.).

The effect of some organophosphorus insecticides [Isofenphos (=Oftanol DS 40), Phorate (=Thimet 10G and Foratox 10-G) and Fonofos] were investigated on soil microbiota (total viable bacteria, actinomycetes, anaerobic bacteria, aerobic endospores, proteolytic bacteria, cellülolytic microorganisms and yeast-mold).
