Sentiment towards BP and Shell has strengthened significantly off the back of oil price spikes. But it’s a complex picture. Neither company has production in Iran. But BP’s significant production in Iraq and Abu Dhabi risks being bottlenecked through disruption to the Strait of Hormuz. For Shell the same applies to its LNG facilities in Qatar and the Emirates.

By WWII, scientists had already begun looking at alternative gelling substances for routine use in bacteriology, but concluded that agar was still better as it is both firmer and easier to handle. Today, some specialized microbiology applications use the colloid carrageenan (extracted from red seaweed Chondrus crispus, or “Irish Moss”), a more transparent and less auto-fluorescent alternative to agar (agar emits its own background fluorescence when excited by light). However, for routine bacteriological use, carrageenan is more difficult to dissolve, requires higher concentrations, can degrade at high temperatures, and forms weaker gels, which may result in puncturing its surface during the plating of cells.。体育直播对此有专业解读
