“…Colony and cell morphology of strain YIM 46034 T were quite similar to those of Dactylosporangium species as described by Vobis (1992), especially with regard to the two types of spores produced. Non-motile spores of Dactylosporangium species were larger (1.7-2.8 mm in diameter) than those of strain YIM 46034 T .…”

A new member of the family Micromonosporaceae, Planosporangium flavigriseum gen. nov., sp. nov. A novel actinomycete, designated strain YIM 46034 T , was isolated from an evergreen broadleaved forest at Menghai, in southern Yunnan Province, China. Phenotypic characterization and 16S rRNA gene sequence analysis indicated that the strain belonged to the family Micromonosporaceae. Strain YIM 46034 T showed more than 3 % 16S rRNA gene sequence divergence from recognized species of genera in the family Micromonosporaceae. Characteristic features of strain YIM 46034 T were the production of two types of spores, namely motile spores, which were formed in sporangia produced on substrate mycelia, and single globose spores, which were observed on short sporophores of the substrate mycelia. The cell wall contained meso-diaminopimelic acid, glycine, arabinose and xylose, which are characteristic components of cell-wall chemotype II of actinomycetes. Phosphatidylethanolamine was the major phospholipid (phospholipid type II). Based on morphological, chemotaxonomic, phenotypic and genetic characteristics, strain YIM 46034 T is considered to represent a novel species of a new genus in the family Micromonosporaceae, for which the name Planosporangium flavigriseum gen. nov., sp. nov. is proposed. The type strain of Planosporangium flavigriseum is YIM 46034 T (5CCTCC AA 205013 T 5DSM 44991 T ).

“…There are suggestions that Micromonospora spp. can grow under microaerophilic conditions (6,15,17), a theory which the environmental data presented here now support. The low oxygen concentrations at greater depth may therefore restrict the growth of other microorganisms more so than that of micromonosporas but remain sufficient to prevent significant growth of strict anaerobes.…”

“…However, the importance of micromonosporas in the ecology of lake sediments remains unknown, particularly as lakes stratify in the summer months, leading to much lower oxygen tensions in the sediments precisely when most of the biological activity occurs. However, there is evidence that micromonosporas can grow under microaerophilic conditions (6,17), and a recent study has described a chicken cecum isolate with 99% 16S rRNA gene sequence homology to Micromonospora that was capable of degrading cyanophycin in anoxic conditions (15).…”

The relative abundance of micromonosporas in the bacterial communities inhabiting cellulose baits, water columns, and sediments of two freshwater lakes was determined by quantitative PCR (qPCR) of reverse-transcribed 16S rRNA. Micromonospora spp. were shown to be significant members of the active bacterial population colonizing cellulosic substrates in the lake sediment, and their increased prevalence with greater depth was confirmed by enumeration of CFU.

“…However, instead of producing aerial hyphae, they develop saclike reproductive structures called sporangia, typically ϳ10 m in diameter (Fig. 1A and D) (13)(14)(15)(16)(17). These sporangia form on the end of short hyphal stalks that arise as simple branches of the vegetative mycelium.…”

Actinoplanes Swims into the Molecular Age

The survival strategy of Actinoplanes is fascinating from an evolutionary perspective, combining a short motile phase in an otherwise nonmotile, filamentous life cycle and the somewhat paradoxical concept of spores-normally thought of as a resting stage-that swim. In the first paper to report a molecular genetic analysis of development in Actinoplanes, the authors identify a key regulator of the entry into development
