Purification and properties of mycoferritin from Mortierella alpina
Canadian Journal of Microbiology, 1972A culture of Mortierella alpina Peyroud isolated from soil and grown on Czapek-Dox medium was found to contain a high concentration of mycoferritin (MF). The MF was extracted from lyophilized mycelium by grinding with 0.1 M, pH 7.0, potassium-phosphate buffer and chloroform followed by differential centrifugation.

Saprolegnia parasitized by Mortierella alpina
Transactions of the British Mycological Society, 1988Mortierella alpina parasitizes the mycelium and oogonia of Saprolegnia hypogyna and S. unispora in pure dual culture. Oospores within infected oogonia disintegrate.

Fermentation Characteristics of Mortierella alpina in Response to Different Nitrogen Sources
Applied Biochemistry and Biotechnology, 2011The fermentation characteristics of Mortierella alpina were investigated in response to various nitrogen sources. Influences on nitrogen source and glucose uptake rate, mycelial morphology of M. alpina, and pH of medium in relation to different nitrogen sources were discussed. Effects of different nitrogen sources on cell growth, fatty acid composition,

Phytohormones as stimulators to improve arachidonic acid biosynthesis in Mortierella alpina
Enzyme and Microbial Technology, 2019Phytohormones are chemical messengers that have a positive effect at low concentrations on the biosynthesis of high-value compounds. Therefore, the effects of phytohormones on lipid and arachidonic acid (ARA) biosynthesis in Mortierella alpina were investigated in this study.

An improved sampling protocol for analysis of intracellular metabolites in Mortierella alpina
Biotechnology Letters, 2012Sampling of intracellular metabolites in Mortierella alpina was investigated as part of a metabolomics study. After comparison of four sampling protocols, rapid filtration of the culture using a laboratory-made nylon filter and absorbent gauze under normal pressure followed by quenching in liquid N(2) and grinding (the improved protocol) was the most ...

Arachidonic acid production by Mortierella alpina grown on solid substrates
World Journal of Microbiology and Biotechnology, 1993Mortierella alpina grown in solid state fermentations on cereal substrates gave up to 16% lipid in the final biomass. Arachidonic was at 50% of total fatty acids, with a yield of 36 mg/g of original substrate. Microbial lipid production was successfully scaled up to use 5-kg dry substrate batches.

Multiple isoforms of malic enzyme in the oleaginous fungus, Mortierella alpina
Mycological Research, 2008Malic enzyme (ME; E.C. 1.1.1.40) is the only enzyme that can provide NADPH for fatty acid biosynthesis in oleaginous micro-organisms. However, it can simultaneously fulfil other roles and may thus exist in different forms, possibly coded for by different genes.

Oil Biosynthesis in Mortierella Alpina Microsomal Membranes
2003Microsomal membrane preparations from Mortierella alpina incubated with sn-glycerol-3-phosphate (G3P) and [14C]oleoyl-CoA catalysed the formation of radioactive phosphatidic acid (PA), diacylglycerol (DAG), triacylglycerol (TAG) and phosphatidylcholine (PC). A similar pattern of radiolabelling was observed when [14C]G3P and non-labelled oleoyl-CoA were

Oil biosynthesis in microsomal membrane preparations from Mortierella alpina
Biochemical Society Transactions, 2000Microsomal membrane preparations from Mortierella alpina catalysed the conversion of sn-glycerol 3-phosphate and [14C]oleoyl-CoA to radioactive phosphatidic acid, diacylglycerol and triacylglycerol. Experiments with lysophosphatidic acid and [14C]oleoyl-CoA gave a similar pattern of radioactivity in the complex lipids.

Lipid Characterization of Mortierella alpina Grown at Different NaCl Concentrations
Journal of Agricultural and Food Chemistry, 2008Effects of sodium chloride (NaCl) concentration on the lipid and fatty acid profiles of the polyunsaturated fatty acid (PUFA)-producing fungus, Mortierella alpina SC9, were investigated. The cells were cultivated in the medium with 4 different NaCl concentrations (0, 1, 2, 4%) for 6 days.
