Abstract
AbstractThe peripheral arrangements of the intra‐cytoplasmic membranes (ICM) as well as the guanine + cytosine (G + C) content of 63% indicate that our obligate methanotrophic strain M 102 would belong to the type II Methylotrophs.There are no active transport mechanisms for some organic additives, some of which are known to stimulate CO2‐fixation. The CO2‐acceptor molecules, Pyr (pyruvate) and PEP (phospho‐enolpyruvate), must be metabolically intracellularly furnished.More than one carboxylating system could be induced in cell fractions. The carboxylating activities were variably registered in cell‐free extracts and fragments. Indications that the site of the carboxylating activities are the ICM are discussed.The fact that the CO2‐fixation intensities decreased at about the middle of the active growing phase indicates that the formation of the intermediate C4‐compound OAA (oxaloaccetate) must be furnished through some reactions by‐passing the PEP‐carboxylation step.The common serine‐pathway for C1‐assimilation is rearranged so as to fit in the discussed findings.
