1. Introduction Bacillus spp. and related genera, including Paenibacillus, Alicyclobacillus, or Brevibacillus, are mostly Gram-positive and have the ability to produce spores and display metabolic capabilities under aerobic as well as relatively anaerobic conditions (Figure 1). Due to their characteristics, bacteria of this group have high resistance to environmental stresses such as drought, water stress, UV radiation, or low nutrient content in the environment [1,2]. Bacillus spp.
