“…Their presence may accelerate the rate of degradation processes or limit the number of specific fungal and bacterial groups [12,13]. Popular fungi used as biostimulants include Glomus intraradices [14], Trichoderma atroviride [14], Trichoderma reesei, and Heteroconium chaetospira [10,[15][16][17][18][19]. Useful bacteria include Arthrobacter spp., Enterobacter spp., Acinetobacter spp., Pseudomonas spp., Ochrobactrum spp., Bacillus spp., and Rhodococcus spp.…”

Biostimulants are among the natural preparations that improve the general health, vitality, and growth of plants and protect them against infections. They can be successfully used in both agri- and horticultural crops. The main active substances used in such preparations are humic and fulvic acids, protein hydrolysates, compounds containing nitrogen, seaweed extracts, beneficial fungi, and bacteria. Biostimulant formulations may be single- or multi-component, but the synergic action of several different components has been observed. Many groups of biostimulants have been distinguished through their method of application (soil, foliar), the material from which they were produced (plant, animal), or the process by which they were created (hydrolysis, fermentation, extraction). Natural soil stimulants can induce the development of beneficial soil organisms that provide substrates for plant growth. The use of natural preparations that are not harmful to the environment is particularly important in connection with the progressive processes of soil degradation and atmospheric pollution. This review gives an overview of the importance and influence of different natural plant biostimulants on both the yield and quality of crops.

“…There is particular interest in Bacillus spp. especially in agriculture applications as some demonstrate the ability to control plant-parasitic nematodes (PPNs; P erez-Garc ıa et al 2011), and more specifically the Meloidogyne genus (Abbasi et al 2014;Zhao et al 2018). The majority of products commercially available for the promotion of plant growth and biological control consist of Bacillus subtilis and Bacillus amyloliquefaciens (Aleti et al 2015).…”

Root‐knot nematodes are destructive phytopathogens that damage agricultural crops globally, and there is growing interest in the use of biocontrol based on rhizobacteria such as Bacillus to combat Meloidogyne species. It is hypothesized that nematicidal activity of Bacillus can be attributed to the production of secondary metabolites and hydrolytic enzymes. Yet, few studies have characterized these metabolites and their identities remain unknown. Others are speculative or fail to elaborate on how secondary metabolites were detected or distinguished from primary metabolites. Metabolites can be classified based on their origin as either intracellular or extracellular and based on their function, as either primary or secondary. Although this classification is in general use, the boundaries are not always well defined. An understanding of the secondary metabolite and hydrolytic enzyme classification of Bacillus species will facilitate investigations aimed at bionematicide development. This review summarizes the significance of Bacillus hydrolytic enzymes and secondary metabolites in bionematicide research and provides an overview of known classifications. The importance of appropriate cultivation conditions for optimum metabolite and enzyme production is also discussed. Finally, the use of metabolomics for the detection and identification of nematicidal compounds is considered.

The rhizosphere soil has a large and various number of microorganisms especially the bacteria. This experiment was conducted at the department of Botany, Jahangirnagar University, Savar, to investigate the rhizospheric and non-rhizospheric bacteria from arsenic contaminated soil. Pteris vittata was treated with different concentrations of arsenic ranges from 5000 to 10000 ppm in the pot. The experimental result indicated that the negative correlation between arsenic concentration and rhizospheric soil bacteria. Highest number of bacteria (8.6×108 cfu/g) were found in rhizospheric soil (control), while lowest numbers of bacteria (4.0×107 cfu/g) were found in the non-rhizospheric soil with 10000 ppm arsenic. Thirty bacteria were isolated from rhizospheric and non-rhizospheric soil samples. Out of thirty samples Bacillus and Pseudomonas were selected on the basis of morphological and biochemical nature. The present study concluded that the arsenic has an adverse effect on the growth of rhizospheric soil bacteria. Jahangirnagar University J. Biol. Sci. 8(1): 9-15, 2019 (June)
