Rhizopus stolonifer is a dangerous mold that can be found on the common bread that we, as humans, consume. Rhizopus stolonifer, a species of bread mold, produces sporangia that bear sporangiospores (asexual spores). Many Rhizopus species are commercially used to produce various chemicals and alcoholic products. 2 Lipase of Rhizopus arrhizus. Some species are used for industrial importance such as Rhizopus stolonifer which caused bread mold. Rhizopus stolonifer is commonly known as black bread mold. The mould is then inoculated in the nutrient egar (N.A.) In both the mycelia, a small outgrowth develops. In conclusion, since foodstuff from which the mould is isolated is bread, Rhizopus SP which is more prominent in bread than in any other foodstuff. (Jay, 1996, De Beer and Beunier 1999).

Rhizopus stolonifer- Black Bread Mold Home Page - BioWeb Home 9 apr 2011 - Well, Rhizopus stolonifer has one particular, very useful ability, which is utilized for medicinal purposes. The cytoplasm is multinucleated and consists of other cell organelles such as mitochondria, endoplasmic reticulum, Golgi bodies, vacuoles and oil droplets, They reproduce by vegetative, asexual and sexual methods, Sporangiophores develop from the upper side of the rhizoidal node, The apical part swells up forming sporangium, as nuclei and cytoplasm move apically, The cytoplasm of sporangium differentiates into the denser peripheral region with more nuclei and the central columella region with fewer nuclei and more vacuoles, Sporangiospores develop inside sporangium. incubated and was isolated and view under the microscope for cultural characteristics. They are able to digest and absorb organic food. Bread, particularly white bread, is an attractive place to land because it is high in starch, a substance that breaks down into sugars, which is a high-energy food for mold. William W.

These three sorts of hyphae as stolons which grow horizontally on the substrate (bread), rhizoid or root like hyphae which arise at points where the stolons come into contact with the substrate and sport-angiophores. ACCOUNTING DEPARTMENT, Item Type & Format: Project Material - Ms Word | These can reproduce by vegetative, asexual and sexual means followed by fragmentation, sporangiospores and zygospores. Rhizopus stolonifer is also known as black bread mold. However, bread is also perishable and spoilage mainly is due to mold growth (28,32). Thallus is white cottony, much branched mycelium. This is known as gametangia, Gametangia conjugate to form a multinucleated structure, Plasmogamy is followed by karyogamy and diploid (2n) zygote is formed. Sporangium bursts and […] 67 pages | Source: COMPUTER SCIENCE, THE CAUSES OF POOR ENROLLMENT OF MALE STUDENT INTO HOME ECONOMICS DEPARTMENT IN TERTIARY INSTITUTIONS, 4,582 hits | Hazard analysis critical control point involves in identifying places in the production process where hazards could occur i.e. They have a branching body known as mycelia. The total price includes only the project material price. Rhizopus oryzae – Alcoholic beverages are produced, Rhizopus microsporus – It is used to get fermented soybean products, Rhizopus reproduce by all the three processes, i.e. Even with this system in place.

Rhizopus species are used to produce alcoholic beverages and chemicals. They are commonly known as black bread mould, pin mould, etc. ACCOUNTING DEPARTMENT, Item Type & Format: Project Material - Ms Word | The mould Rhizopus arrhizus secretes an extracellular lipase that has a near absolute specificity for the primary bonds of glycerolipids. Rhizopus is a type of fungus which belongs to the class Zygomycetes because of the fact that it produces zygospore in its sexual reproductive phase. The majority of Rhizopus species are saprobic (decomposers) and feed on a variety of dead organic matter, though some species are parasitic or pathogenic. 62 pages | Source: ENVIRONMENTAL SCIENCE, THE EFFECT OF EARLY MARRIAGE ON FEMALE ACADEMIC PERFORMANCE, 5,300 hits | Hi - Filamentous fungi and Rhizopus are responsible for spoilage of.
