“…(Schulze, 2011). "EPA (C20:5) and the very long-chain omega-9 fatty acids C22:1 and C24:1 are striking for this alga, the latter presumably being related to nervonic acid, which has been considered for the treatment of demyelinating disorders of neurons (Coupland & Langley, 1993;Tang et al, 2013). Psychrophilic Chlamydomonas and Chloromonas, though obligatorily adapted to low temperatures, did not produce any noticeable amounts of long or very long chain PUFAs.…”

The CCCryo Culture Collection of Cryophilic Algae is a diverse bioresource of mainly coldadapted microalgae from polar environments. It currently comprises 518 strains of 178 species in 101 genera. Most strains were isolated from field samples collected during seven polar expeditions, mainly to Svalbard (Norway) and Antarctica. Almost 90% of the strains are cryophilic, with 33% of all strains being psychrophilic (obligate cryophilic) representing the "true" snow algae and 56% being psychrotrophic (non-obligate cryophilic), comprising other snow and permafrost algae from cold habitats. There are also some cultures of mosses, cyanobacteria, fungi and bacteria from cold or thermal environments. These strains are publicly available and serve as a rare bioresource for fundamental studies as well as for the development of commercial products. Basic studies address taxonomic and phylogenetic as well as physiological questions and genome and transcriptome research, whereas applied studies mostly address the capabilities of cryophilic algae to produce commercially interesting products for markets like food, feed and supplements, cosmetics, tools for molecular biology and diagnostics or food processing. Examples of strains studied for the production of valuable polyunsaturated omega-3 fatty acids like EPA, secondary carotenoids like astaxanthin, ice-structuring proteins, cold-active enzymes, UV-absorbing mycosporine-like amino acids and extracellular polymeric substances as form stabilizers are given and discussed in the context of customers' acceptance, legal regulations for specific markets, technical feasibility of an industrial production process, potential profit and chances for the successful development of a commercial product.

“…Besides conservation urgency, M. oleifera is also notable for its substantial phytochemical and phytopharmaceutical value. Its seed has very high (64.5%) oil content [10, 11] and the highest-known proportion (55.70%–67%) of nervonic acid (C 24 H 46 O 2 , PubChem CID: 5281120). Nervonic acid is an important component in myelin biosynthesis in the central and peripheral nervous system.…”

Background Malania oleifera , a member of the Olacaceae family, is an IUCN red listed tree, endemic and restricted to the Karst region of southwest China. This tree's seed is valued for its high content of precious fatty acids (especially nervonic acid). However, studies on its genetic makeup and fatty acid biogenesis are severely hampered by a lack of molecular and genetic tools. Findings We generated 51 Gb and 135 Gb of raw DNA sequences, using Pacific Biosciences (PacBio) single-molecule real-time and 10× Genomics sequencing, respectively. A final genome assembly, with a scaffold N50 size of 4.65 Mb and a total length of 1.51 Gb, was obtained by primary assembly based on PacBio long reads plus scaffolding with 10× Genomics reads. Identified repeats constituted ∼82% of the genome, and 24,064 protein-coding genes were predicted with high support. The genome has low heterozygosity and shows no evidence for recent whole genome duplication. Metabolic pathway genes relating to the accumulation of long-chain fatty acid were identified and studied in detail. Conclusions Here, we provide the first genome assembly and gene annotation for M. oleifera . The availability of these resources will be of great importance for conservation biology and for the functional genomics of nervonic acid biosynthesis.

“…Lunaria biennis seed oil contains 42% erucic acid as well as 21% C24:1, ω ‐9 nerbonic acid, which is predominantly in mammals. Seed oil from Malania oleifera, which grows in south China, contains more than 55.7% nerbonic acid. Ximenia seed oil, from Africa and South America, is the longest fatty acid in vegetable oil.…”

Bio‐oil contains plant, animal, fish, and micro‐algae oil, and more than 200 million tons are produced annually. However, many edible and non‐edible bio‐oils are still under development, and their value and feasibility have yet to be determined. The vast majority of bio‐oils produced in the world have a very high unsaturated fatty acid content (70–98%), which could be used as a renewable, eco‐friendly alternative to petroleum. Hydrolysis (or transesterification) with ethylene metathesis technology converts unsaturated fatty acids to C4–C30 oil fragments. These oil fragments are a sustainable chemical technology used in chemical industry platform technology and carbon dioxide abatement green chemical technology, and as a petrochemical substitute. These platform chemicals also have their own market but are used as raw materials for other products (polymers, surfactants, synthetic lubricants, plasticizers, other specialty chemicals, general purpose chemicals, biofuels, etc.). The biodegradability and biocompatibility of the polymeric materials made from the oil mean that it is also possible to develop diverse functional products with high added value such as toothpaste, dandruff treatment shampoo, and melanin pigment removal cosmetics, medical and shape memory polymer materials. According to the cradle‐to‐gate analysis for environmental impact and economics, the total carbon dioxide emission reduction per ton of soybean oil was estimated to be 1.5 kg kg−1 products. Moreover, the metathesis of soybean oil ($680/ton) with additional raw materials ($237.4) will generate a value that is 7.5 times higher at $6857. Due to the biodegradability and biocompatibility of the products made from bio‐oils, it is expected that various functional products with high added value will be developed and that industrial applicability will be greatly expanded in the near future. In addition, for the development of various derivatives, fusion and cooperative research in chemical fields such as catalytic engineering, organic chemistry, polymer chemistry, maintenance chemistry, and reaction engineering are essential. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd
