“…However, in this case, HCN + Bacillus were supposed to be implicated in the plant pathogenicity (Benizri et al, 2005). Until today, no reports on the relationship between Bacillus HCN production and biocontrol activity is found in literature.…”

Bacillus thuringiensis beyond insect biocontrol: plant growth promotion and biosafety of polyvalent strains

The entomopathogenic bacterium Bacillus thuringiensis is widely used for the control of many agricultural insect pests and vectors of human diseases. Several studies reported also on its antibacterial and antifungal activities. However, to our knowledge there were no studies dealing with its capacity to act as a plant growth promoting bacterium. This review surveys the potential of B. thuringiensis as a polyvalent biocontrol agent, a biostimulator and biofertiliser bacterium that could promote the plant growth. Also, discussed is the safety of B. thuringiensis as a bacterium phylogenetically closely related to Bacillus cereus the opportunistic human pathogen and Bacillus anthracis, the etiological agent of anthrax.

“…In this case, one of the reasons for the lack of effectiveness of the inoculant in increasing the enzymatic activity of replanted soil can be a low degree of root colonization by mycorrhizal fungi. This probably results from the accumulation of a range of compounds limiting the development of the soil microflora -phenolic acids, glycosides or allelopathic compounds (Benizri et al, 2005;Styla, 2014).…”

The studies were conducted at two sites (a replantation and a virgin soil site). The following two combinations were used for each of the sites: control with no treatments applied and with the application of a mycorrhizal vaccine on the root balls of the plants at the time of planting. The four-year research showed that the way of soil usage had an influence on its biochemical properties, which were evaluated on the basis of enzymatic activity, which, except for the dehydrogenases, was at a lower lever in the replanted soil site. The use of a mycorrhizal vaccine did not increase the enzymatic activity in the replanted soil site, sometimes even lowered it. The content of organic matter defined as the total content of carbon and dissolvable carbon in the soil was higher at the replanted site than at the virgin soil one. The use of the mycorrhizal vaccine contributed to the increase of the content of the organic matter but only in the virgin soil site. The soil from the plantation growing on the virgin soil was characterized by the highest content of proteolytic bacteria and the highest respiratory activity.

“…Many researches indicated that there were soil physiochemical property disorders, soil microbial community changes and autotoxicity are responsible for the soil sickness (Yu and Matsui, 1994;Yang et al, 2012;Mazzola and Manici, 2012). Previous studies report that soil microflora change is one of the major causes in soil sickness in Cistus ladanifer (Hassan et al, 1989), peach (Benizri et al, 2005), cucumber (Yao et al, 2006), Rehmannia glutinosa (Zhang et al, 2011), Liriope (Zhao et al, 2010) and apple (Yim et al, 2013).…”

Angelica sinensis (Oliv.) Diels (family Apiaceae) is a perennial herb that has been widely used in Traditional Chinese Medicine. The soil sickness has become one of the major constrains in A. sinensis cultivation. A pot experiment was done to evaluate the role of biological nature in A. sinensis soil sickness. The pot experiment include three treatments (i) contol, which represent as the soil in pot taken from spring wheat stands, (ii) AA, which represent as the soil in pot taken from A. sinensis stands, (iii) S-AA, which represent as the soil in pot was sterilized by steam at 121℃ for 4 h taken from A. sinensis stands.Results showed that the plant height, dry weight of aboveground part and roots, root yield and quality, and the activities of SOD and POD in leaves were significantly higher in sterilized replant soil than in non-sterilized replant soil treatment, while the activity of CAT and content of MDA in leaves were declined, which indicated that soil sterilization improved plant haleness and increased the activities of active oxygen scavenging enzymes. The results also demonstrated that soil sterilization can change the number of culturable microbial populations and the species diversity of bacterial functional group. Higher Shannon-Wiener index was found in rhizosphere soils under sterilized soil cropping than that under non-sterilized soil cropping. This suggests that the biological factor played a causal role in the development of A. sinensis soil sickness and sterilization of continuous cropping soil could change the composition and structure of soil microbial community, which further promote plant growth and alleviate A. sinensis soil sickness.
