Concentrations of DOC and DO in all light treatment primary producer incubations exhibited changes significantly different from zero over the course of the 8 hour incubations (p<0.01) and rates of release in all treatments were significantly greater than the controls (Dunnett’s p<0.01; Figure S2).

Marine production is dominated by algae and plankton. Types of Producers. There are two major types of primary producers – phototrophs and chemotrophs.

Marine photosynthetic plankton are responsible for approximately 50 petagrams (10 15) of carbon per year of net primary production, an amount equivalent to that on land.This primary production supports essentially all life in the oceans and profoundly affects global biogeochemical cycles and climate.

Scientists at The University of East Anglia (UEA) have discovered a gene which regulates the size of diatoms, which contribute 20 per cent of global primary production. unknown genetic control of.

However, the natural origins of PBDE biosynthesis are not known. Here we report marine bacteria as producers of PBDEs and establish a genetic and molecular foundation for their production that unifies.

Naturally occurring β-lactam compounds fall into four basic structural groups, the penicillins/cephalosporins, the clavams, the carbapenems and the monocyclic β-lactams. Biosynthetic studies have.

Nitrite, an intermediate product, accumulates at the base of the sunlit layer in the subtropical ocean, forming a primary nitrite maximum, but can accumulate throughout the sunlit layer at higher.
