Why don’t plants have defences against mycorrhizal infection? As we know The relation between the fungi and the plant is mutualistic , where the fungi take carbohydrates and vitamins from the
(2009) also observed highest plant height, number of branches, number of umbels, dry weight and fruit yield per plant of coriander with the treatment combination of Azospirillum + 50 % N. Bio-fertilizers add nutrients through the natural processes of nitrogen fixation and stimulating plant growth through synthesis of growth promoting substances and might have positively influenced the crop yield. The beneficial role of supplemented organic manures and bio-fertilizers in improving soil physical, chemical and biological role is well known, which in turn helps in better nutrient absorption by plants and resulting higher
Dr Tracy Ainsworth stated “it is very likely that these microorganisms play a vital role in the capacity of coral to recovering from bouts of bleaching caused by rising temperatures.” Corals rely on these good bacteria’s crucially although we don’t yet understand these microbe’s ell enough to know how they influence coral survival, which is vital in maintaining the food web of the Great Barrier Reef. These good bacteria as well as other decomposers break down dead organics material and turn nutrients to the sediment. This energy is then obtained by the producers and the cycle begins
Fungal diseases have been recently introduced into the medical field. Fungi are a part of the domain Eukarya, where it once was considered in the plant kingdom. The domain Eukarya is consistent with eukaryotic organisms that contain a nucleus and other membrane-bound organelles. Fungal diseases are more difficult to treat compared to antibiotics for bacterial diseases because the fungus and the host are eukaryotic organisms. Therefore, any treatment of the fungus may affect the host too and can develop resistance to antifungal medication.
Bacteria and fungi feed on organic matter in the soil. As they do this they store nutrients within their body while releasing others. The nematodes and protozoa in the castings turn prey on them and nutrients are released from the beneficial and fungal bodies into the soil in a plant available-form ready for root
Also, cellulose present plant cell wall is degraded by fungi like Aspergillus, Fusarium, Trichoderma and bacterial aspecies like Vibrio, Cellulomonas, Polyangia, Cytophaga, Streptomyces present in gut of earthworms. (Imshenetsky 1967,Ljungdahl and Eriksson, 1985). Bacterial species like Bacillus and Pseudomonas in addition to cellulose degradation also solubilise the soil phosphate ( Vijayakumar et al., 2009) (Imshenetsky 1967; Ljungdahl and Eriksson, 1985). On the other hand along with degradation of cellulose Aspergillus niger also degrades lignin and fungus is also known for lignin breakdown. ((Imshenetsky 1967; Ljungdahl and Eriksson, 1985; Krause et al., 2003; Malherbe and Cloete
Thus, the amount of P liberated by them is generally not sufficient for a substantial increase of in in situ plant growth. Therefore, inoculation of plant by desire microorganism at adequate amount than the normal found in soil is necessary to take advantage of the property of phosphate solubilization for plant growth and yield enhancement (Rodrigues H and Fraga R, 1999). OBJECTIVES In the context of above observations, the present investigation was carried out with the following objectives: 1.1. Objectives of the Study • To isolate the phosphate-solubilize bacteria from rhizosphere of maize plants, • To detect the phosphate-solubilizing ability, • To characterize the microorganisms at the phenotypic and genotypic level, • To study the diversity of phosphate solubilizing bacteria, • To examine the production of organic acids, • In addition, this study was to examine the effect of phosphate-solubilizing bacteria as inoculants on plant growth and yield and may be used as biofertilizer. • We also hypothesize that the combined effect of microbial strain can also give better result as compared to the single
IMPACT OF FUNGI ON HUMANS Fungi are eukaryotic, sporulating, heterotrophic organisms which acquire nutrients through absorption. Their vegetative bodies are made up of thalli and reproduce both asexually and sexually, although in some the sexual stage is not known. Various classes exist; basidiomycetes, ascomycetes, deuteromycetes, zygomycetes and oomycetes. The impact of fungi on humans cannot be underestimated. They play vital roles in the ecosystem, including the wellbeing of man.
In a bid to mechanize the various unit operations involved in the post-harvest processing of neem seeds, information and data on the behavior of these strength properties as a function of moisture is needed. Hence, the study of moisture dependent thermo-mechanical properties of neem seed. Parameters and information obtained will help in harnessing the potential benefits of neem seed. The utilization of the data generated would save energy and promote the design and development of appropriate, effective and efficient process machines. Besides processing and preservation, thermal conductivity and other properties such as specific heat and thermal diffusivity also affect the sensory quality of foods as well as energy saving during processing (Opoku et al., 2006).
The scientific question that is in my research. Does microorganism have an effect to the formation and destruction of coral reefs? .What could factor can affect the interaction of a microorganism in a coral reefs and how can they benefit each other? C. Significance of the Study In my study it is good for people to know how important coral reefs are in our world and this is also important in marine resources because the coral reefs are a breeding grounds of fishes and they also source food, the fishes eat microorganisms that grow in corals or grow near in coral reefs. Coral reefs takes about 10,000 years before the coral reefs are completely formed and it can destroy quickly by several factor.
