Aspergillus nidulans is able to grow on oleic acid as sole carbon source. Characterization of the oleate-induced beta-oxidation pathway showed the presence of the two enzyme activities involved in the first step of this catabolic system: acyl-CoA oxidase and acyl-CoA dehydrogenase. After isopicnic centrifugation in a linear sucrose gradient, microbodies peroxisomes housing the beta-oxidation enzymes, isocitrate lyase and catalase were clearly resolved from the mitochondrial fraction, which contained fumarase.
Growth on oleic acid was associated with the development of many microbodies that were scattered throughout the cytoplasm of the cells. The beta-oxidation pathway was also induced in acetate-grown cells, although at lower levels; these cells lacked acyl-CoA oxidase activity. Nevertheless, growth on acetate did not cause a massive proliferation of microbodies in A. Abstract Aspergillus nidulans is able to grow on oleic acid as sole carbon source.

Medical browser? Full browser?Microbodies:- Microbodies are small single membrane-bound organelle. They are formed by ER. They were first observed by Rhodin. They Found in protozoa, fungi, plants, and liver and kidney cells. Microbodies are four types:- 1. Peroxisomes:- Peroxisomes help in detoxifying the alcohol in the liver cell. Contains amino acid oxidase, hydroxyl acid oxidase, peroxidase, catalase enzymes.
Microbodies – Structure, functions, and Types
Their catalase enzymes degrade H2O2. In animal cells peroxisomes they perform fat metabolism, peroxide metabolism. In plant cells, photorespiration occurs in peroxisome with mitochondria and chloroplast. Glyoxysomes: — These were first seen by Harry Beaver. Found in fungi and germination oil seed eg.
Castor seed, groundnut seed etc. These are involved converting fat into carbohydrates by process gluconeogenesis. Glyoxylate cycle occurs in Glyoxysomes. Groundnut sees become sweet due to glyoxylic acid. Spherosomes: — These are a single membrane, small, spherical cell organelles that are specialized to synthesize and store lipids example- Cell of cotyledons mustard, groundnut etc.
Found in fat storing plant cells but are abundant in oilseeds E. Maize root tip, tobacco endosperm. Lomesome: — Discovered by moor and McAlear. Found between the cell wall and plasma membrane of fungal and plant cell. They are also known as a Paramural body, plasmalemmasomes if associated with plasma membrane.

Related Articles.Micro bodies are small cell organelles bounded by single membrane which absorb molecular oxygen and take part in oxidation other than those involved in respiration. These submicroscopic bodies were observed for the first time in in the mouse kidney tubule cells with the help of electron microscope. They are present in almost all eukaryotic cells. They are mostly seen near the endoplasmic reticulum ERand sometimes near mitochondria and plastids.
These are oxidative bodies and play important role in the metabolism of fats, sugars and amino acids. These micro bodies are found in both animals and plants. They were discovered by Rhodin inand studied in detail by Tolbert in Since they contain enzymes for peroxidase synthesis, they are called peroxisomes.
They are found in close association with ER, mitochondria and chloroplasts. In animals, they can be seen in liver and kidney cells. They are found in abundance in photosynthesizing cells; and each such cell may contain up to peroxisomes.
They develop from ER, and their shape and size are variable mostly 0. Each peroxisome is covered by a single unit membrane.
They have a matrix of fine granules in the central part of which there is a homogeneous and opaque and fibrous core Fig. In animal cells, peroxisomes take part in oxidation of a number of bio-chemicals including may also take part in lipid metabolism.
They are found in abundance in plant cells in which photorespiration takes place i. During photorespiration, green plants release CO 2 during day time. The peroxisomes contain enzyme glycolic acid oxidase that oxidises glycolic acid, a product of photosynthesis, to glyoxylic acid, a process called photorespiration.
The glyoxylic acid may give rise to succinic acid or change into an amino acid glycine. The succinic acid may enter Krebs cycle or change into glucose. The amino acid glycine takes part in protein synthesis.
The plant peroxisomes possess enzymes for all these metabolic processes. These micro bodies were discovered by Beeversand studied by Briedenbach in They are very small spherical bodies with single unit membrane found only in plants Fig.
They contain enzymes for glyoxylate pathway. It also helps in conversion of stored lipid in germination oil seeds into glucose called gluconeogenesis. Top Menu BiologyDiscussion.
