Lipopeptide overproduction by cell immobilization on iron-enriched light polymer particles [PDF]
, 2009 The study concerns surfactin and/or fengycin batch production by immobilized cells of Bacillus subtilis ATCC 21332. Light carriers designed for a three phase inverse fluidized bed biofilm reactor (TPFIBR) were used.

Isolation of a novel mutant from Bacillus subtilis natto [PDF]
Nucleic Acids Symposium Series, 2006 For the construction of strains with full probiotics function in intestines, deoxycholate resistant mutants were isolated from Bacillus subtilis natto. The partial characterization of the mutants was carried out and described.

A novel Bacillus natto plasmid pLS32 capable of replication in Bacillus subtilis [PDF]
FEBS Letters, 1998 Plasmid pLS32 is a relatively large (approximately 70 kbp), cryptic, low copy‐number plasmid present in Bacillus natto. We isolated and analyzed the replication region of the plasmid in B. subtilis, and the following results were obtained: the replication region contained an open reading frame encoding a 287‐amino acid protein (RepN), whose amino acid ...

The Quality of Natto Produced by the Sporulation Mutants of Bacillus subtilis (natto)
Nippon Shokuhin Kagaku Kogaku Kaishi, 2010 納豆菌胞子を含まない納豆の開発および，胞子形成と納豆の品質の関係を明らかにするため，納豆菌胞子形成変異株であるspo0A, sigH, sigE, sigF, sigKおよびsigGの破壊株を用いて納豆を作製し評価した．その結果，胞子形成初期の変異株であるspo0AおよびsigHの各破壊株では菌膜の被り，糸引きが弱く，L-グルタミン酸含量も少なかった．しかし，胞子形成中期以降の変異株であるsigE, sigF, sigK, sigGの各破壊株では，L-グルタミン酸含量およびアンモニア含量の増加傾向がみられたが，官能評価では野生株との明確な差はみられなかった．これらの結果から，納豆製造には胞子形成の初期が重要であること，納豆菌胞子を含まない納豆を製造するためには ...

The Bacillus subtilis conjugative transposon ICEBs1 mobilizes plasmids lacking dedicated mobilization functions [PDF]
, 2012 Integrative and conjugative elements (ICEs, also known as conjugative transposons) are mobile elements that are found integrated in a host genome and can excise and transfer to recipient cells via conjugation.
