“…These three species were subsequently described as members of Sporosarcina by Yoon et al (2001). Recently Ahmed et al (2007) proposed the transfer of two additional rRNA group 2 Bacillus species, i.e. B. fusiformis and B. sphaericus, into a newly created genus Lysinibacillus and Albert et al (2007) proposed a new genus Viridibacillus to include the species Bacillus arvi, Bacillus arenosi and Bacillus neidei.…”

“…Except for B. silvestris, data for peptidoglycan composition, polar lipids and often fatty acids are lacking for those Bacillus species that together with B. silvestris belong to the same clade (B. odysseyi, B. massiliensis, B. pycnus). Many investigators have suggested that species placed within the genus Bacillus in Bacillus rRNA group 2 do not belong to it and should be reclassified either into novel genera or into pre-existing genera within the group (Farrow et al, 1994;Yoon et al, 2001;Ahmed et al, 2007;Albert et al, 2007). As for the taxonomic position of B. odysseyi, B. massiliensis and B. pycnus, all three species seem to be phylogenetically distantly related to B. silvestris (Supplementary Table S1 and Fig.…”

Re-examination of the taxonomic position of Bacillus silvestris Rheims et al. 1999 Following the transfer of three of the six species enclosed in the original definition of rRNA group 2 of Bacillus to the genus Sporosarcina and two to Lysinibacillus, other species of this group, some of which were added later, still await taxonomic revision. In a recent publication, a set of 'core' characteristics was proposed for species to be included in the genus Bacillus (Kä mpfer et al., 2006). Except for Bacillus silvestris, however, several or none of these properties are available for members of rRNA group 2. According to our analysis of data including the 'core' characteristics, Bacillus silvestris should not be a member of the genus Bacillus. We therefore propose the establishment of a new genus, Solibacillus gen. nov., and transfer Bacillus silvestris to this genus as Solibacillus silvestris comb. nov., with the type strain HR3-23 T (5DSM 12223 T 5ATCC BAA-269 T 5CIP 106059 T ).In a major systematic study based on the 16S rRNA gene sequence analyses of the members of the genus Bacillus, Ash et al. (1991) recognized five distinct groups and proposed that absence of phenotypically definable criteria 'should not preclude the recognition of these groups as distinct genera'. Subsequently, species belonging to rRNA group 3 were placed in a new genus, Paenibacillus (Ash et al., 1993;Shida et al., 1997). Bacillus rRNA group 2 comprises six Bacillus species: Bacillus fusiformis, Bacillus globisporus, Bacillus insolitus, Bacillus pasteurii, Bacillus psychrophilus and Bacillus sphaericus, and also the nonBacillus species Sporosarcina ureae. An increasing number of species descriptions indicated the need to properly define the properties of the genus Bacillus (Farrow et al., 1994;Rheims et al., 1999;Stackebrandt & Swiderski, 2002; Kämpfer et al., 2006;Zhang et al., 2007) and according to Farrow et al. (1994) the 'simplest and most phylogenetically consistent policy would be to exclude the group 2 bacilli from the genus Bacillus'. The same authors also suggested the transfer of B. globisporus, B. pasteurii and B.psychrophilus to the genus Sporosarcina. These three species were subsequently described as members of Sporosarcina by Yoon et al. Supplementary tables showing 16S rRNA gene sequence similarity between Bacillus silvestris and other closely related members of Bacillus rRNA group 2, and comparative fatty acid profiles of B. silvestris, Caryophanon latum and Bacillus subtilis are available with the online version of this paper.

“…One strain was identified as Lysinibacillus sphaericus after differentiating it from L. fusiformis, based on the ability to hydrolyze urea. These two species, formerly assigned to Bacillus, have been recently transferred to the new genus Lysinibacillus (Ahmed et al 2007). L. sphaericus is commonly used in the biological control of various families of insects (Alexander and Priest 1990;Woodburn et al 1995;Rippere et al 1997;Salama et al 2004).…”

Biological activity of Bacillus spp. evaluated on eggs and larvae of red palm weevil Rhynchophorus ferrugineus

et al. 2014

This study was conducted to characterize the Bacillus populations associated with dead Rhynchophorus ferrugineus, to develop a biological control for the red palm weevil. Dead adult beetles, collected throughout Sicily, were used for isolating internal and external spore forming bacteria (SFB) microbiota. The isolates, preliminarily allotted to the Bacillaceae family, were tested at four concentrations (10 3 to 10 6 CFU/mL) for their ability to inhibit hatching of eggs of R. ferrugineus and were used at 10 6 CFU/mL to monitor their insecticidal activity against 10-day-old larvae. Total amounts of SFB measured outside the skeleton and in the inners part of the beetles were 5.59-6.94 and 5.17-7.05 Log CFU/g, respectively. Hatching was markedly inhibited by nine isolates, representing nine distinct strains of seven species (Bacillus amyloliquefaciens, Bacillus cereus, Bacillus licheniformis, Bacillus megaterium, Bacillus pumilus, Bacillus subtilis, and Lysinibacillus sphaericus), especially by the strains B. pumilus GC43 and GC51, which exhibited lethal concentrations 50 (LC50) values of 1.60×10 3 and 9.84×10 3 CFU/ mL, respectively. Among all the strains tested, only B. licheniformis CG62 exhibited significant insecticidal activity against red palm weevil larvae. The Bacillus isolates characterized and tested in this study inhibited the hatching of red palm weevils in a contact-dependent manner. Thus, these isolates can be used as a preventive rather than as a curative treatment.

“…6) To explore B-tolerant microorganism in the natural environment, we have isolated Algoriphagus boritolerans, Bacillus boroniphilus, Gracilibacillus boraciitolerans, and Lysinibacillus boronitolerance. [7][8][9][10] B-tolerant isolates are potential genetic resources for B-resistant genes, which function to adapt an organism to extreme environments. By the use of bioengineering technology, these genes can be used to confer Btolerance to agricultural crops in naturally B-contaminated areas.…”

“…This is consistent with our previous studies showing that B-tolerant strains such as Bacillus boroniphilus, Gracilibacillus boraciitolerans, and Lysinibacillus boronitolerans are moderately halotolerant. [7][8][9][10] To determine the B concentration in the cells, BTM4c and the reference strains were grown at 25 C for 2 d in 5 ml of TSB medium containing 100 mM boric acid. Then they were harvested and washed in TSB medium, and examined for B content by ICP-MS.…”
