“…Paenibacillus strains can also degrade pollutants derived from extracting, refining, and transporting petroleum and coal tar, including crude oil [129], diesel fuel [130], bitumen [131], disulfide oils [132]; and the polycyclic aromatic hydrocarbons (PAHs) naphthalene [133], phenanthrene [134], and pyrene [135]. Strains can also degrade the chemical gasoline additives ethyl tert-butyl ether [136] and benzene [134], the latter of which is also used in the production of chemicals and plastics, including nylon.…”

Isolated from a wide range of sources, the genus Paenibacillus comprises bacterial species relevant to humans, animals, plants, and the environment. Many Paenibacillus species can promote crop growth directly via biological nitrogen fixation, phosphate solubilization, production of the phytohormone indole-3-acetic acid (IAA), and release of siderophores that enable iron acquisition. They can also offer protection against insect herbivores and phytopathogens, including bacteria, fungi, nematodes, and viruses. This is accomplished by the production of a variety of antimicrobials and insecticides, and by triggering a hypersensitive defensive response of the plant, known as induced systemic resistance (ISR). Paenibacillus-derived antimicrobials also have applications in medicine, including polymyxins and fusaricidins, which are nonribosomal lipopeptides first isolated from strains of Paenibacillus polymyxa. Other useful molecules include exo-polysaccharides (EPS) and enzymes such as amylases, cellulases, hemicellulases, lipases, pectinases, oxygenases, dehydrogenases, lignin-modifying enzymes, and mutanases, which may have applications for detergents, food and feed, textiles, paper, biofuel, and healthcare. On the negative side, Paenibacillus larvae is the causative agent of American Foulbrood, a lethal disease of honeybees, while a variety of species are opportunistic infectors of humans, and others cause spoilage of pasteurized dairy products. This broad review summarizes the major positive and negative impacts of Paenibacillus: its realised and prospective contributions to agriculture, medicine, process manufacturing, and bioremediation, as well as its impacts due to pathogenicity and food spoilage. This review also includes detailed information in Additional files 1, 2, 3 for major known Paenibacillus species with their locations of isolation, genome sequencing projects, patents, and industrially significant compounds and enzymes. Paenibacillus will, over time, play increasingly important roles in sustainable agriculture and industrial biotechnology.Electronic supplementary materialThe online version of this article (doi:10.1186/s12934-016-0603-7) contains supplementary material, which is available to authorized users.

“…However, the researchers have worked on soil remedation and some processes are developed to convert DSO to sulfur containing organic products or production of thiophene from dialkyl disulfides . But the DSO problem has not been solved in Iran so far.…”

Disulfide oil (DSO) is produced as a hydrocarbon sulfide waste stream in liquefied petroleum gas and condensate sweetening units in refineries and can cause acute environmental pollutions. In this article, a simple process composed of two units including a distillation unit and a hydrodesulfurization (HDS) unit is proposed to overcome the disulfide oil problem in refineries. The commercial HDS catalyst is CoMo type that is applicable for hydrotreating of DSO. This catalyst is developed by different licensors such as Axens. The high sulfur content in DSO feed causes an increase in heat of reaction and partial pressure of H2S in HDS reactor. By using special design techniques such as reactor quenching or increase H2/oil ratio, the reactor can be designed properly for DSO feed. The waste stream DSO is converted to valuable products including: dimethyl disulfide (DMDS), sweet gas and condensate. A process flow diagram consisting of distillation and HDS units together with amine treating and hydrogen compression system is proposed and simulation of the process is carried out by Aspen plus: The distillation unit separates DMDS and the HDS unit removes sulfur from remainder DSO. Capital cost estimation methodology is based on bare module factor. The capital and operating cost of the process are estimated for a real capacity of DSO just produced in south pars of Iran. Financial parameters and sensitivity analysis show that the process is feasible both technically and economically with an internal rate of return of 73.6%. The proposed process is accepted environmentally by converting a harmful waste to saleable products.
