Maturation culture

Algal blooms in fresh water ponds occasionally poison livestock and waterfowl. Axenic cultures of Anabaena flos-aquae NRC 44-1 were shown to produce the toxic principle (5) which can be present in the algae and in the water of mature cultures (6). The discovery of the toxin was fortuitous in the sense that AChR agonists do not have a (known) constructive function in the algae evolution of the synthetic pathway was likely a by-product of metabolic pathways in the algae. The compound became evident only through its toxic effects on other organisms. 

The slant was inoculated with ATCC 23342 and incubated for 6 days at 30°C. The culture does not normally sporulate on this medium, and it is necessary to macerate the mycelial mat with a flattened, sharpened, inoculating needle in order to increase the number of potential growth centers. The macerated mature culture was covered with sterile distilled water and scraped carefully with a sterile rod to obtain a mycelial suspension. 

Catterall Francois Couraud s lab in Marseilles has done similar experiments on cultured brain neurons from early embryos, and finds a similar Na dependent internali2ation and down-regulation of Na channels. However, this is not observed in more mature cultures of neurons. Do you see the same correlation between the age of the neurons and the abihty to down-regulate Na channels ... 

Volatile fungal metabolites contribute to the organoleptic properties of several other foodstuffs. Surface mould ripened cheeses such as Brie and Camembert are produced using Penicillium camembertii and, more commonly, P. caseicolum. Oct-l-en-3-ol accompanied by smaller amounts of octa-l,5-dien-3-ol and 3-one are major contributors to the aroma. These organisms also have the ability to produce 2-alkanones from fatty acids and these contribute to the odour of the cheese. 2-Methylisoborneol (7.70) and 2-methoxy-3-isopropylpyrazine (7.71) have been detected in mature cultures. An unpleasant earthy flavour encountered in some aged cultures has been attributed to the excessive produetion of 7.71. 

Cultures are incubated at room temperature for 5-7 days, and mature cultures are stored in a cold room ( 4°C) for plating.

Broodstock are cultured in earthen ponds. Normally, hatcheries have many potential broodstock ponds and a smaller number of conditioning and maturation culture ponds (Rg. 16.7). On average, about eight (range 3-25) ponds are used for maintaining the large number of potential broodfish. The ponds are around 0.16 ha (from 0.02-3.0 ha) and 3-4 m deep. 

The terminologies of COHSIS adopted in this paper, and to help on its usability, were HFE, SHE, and SHEE. The main selected organizations with mature culture in COHSIS or its individualized structures, in the temporal sequence of the reference list, were DuPont, Wood Group, Shell International Limited, and Volvo Car Corporation.
