Methylocystaceae
family of bacteria
The Methylocystaceae are a family of bacteria that are capable of obtaining carbon and energy from methane. Such bacteria are called methanotrophs, and in particular the Methylocystaceae comprise the type II methanotrophs, which are structurally and biochemically distinct from the Methylococcaceae or type I methanotrophs.
In this family methane is oxidized to form formaldehyde, which is assimilated by the serine pathway. This involves combining formaldehyde and glycine to form serine, which may be converted into glyceraldehyde and thus into other organic molecules. They can also fix nitrogen, like many other members of the order Hyphomicrobiales. The cells contained paired internal membranes which are arranged towards their periphery.
The public source identifies “Methylocystaceae” as family of bacteria. This brief keeps that definition visible, then builds a research path around Methylocystaceae, family and bacteria.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Methylocystaceae”, the useful work is to connect “family of bacteria” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Feb 11, 2026. The linked authority identifier is Q6824044. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
