The MACD line is the 12-day exponential moving average less the 26-day EMA. Typically closing prices are used. Exponential moving averages are similar to simple moving averages, except that more weight is given to the latest data.
The most common genera of mold fungi identified in air samples are Penicillium, Cladosporium, and Aspergillus. Others that are frequently reported include Alternaria, Stachybotrys, Aureobasidium, Chaetomium, Epicoccum, and Ulocladium. Many species of fungi are known to cause allergies.
It took around 2,000 L of mold culture fluid to create enough pure penicillin to treat just a single case of sepsis in a person. Penicillium notatum simply could not produce enough penicillin. However, another chance discovery on a slice of cantaloupe introduced the group to Penicillium chrysogenum.
