Two major pathways are involved in isoprene synthesis. The mevalonate pathway is present in eukaryotes, archaebacteria and cytosol of higher plants whereas the non-mevalonate pathway exists in many eubacteria and plastids in algae/plants. There have been continuous efforts to study and understand the phenomenon of biological production of isoprene for more than half a century. Although, the current feasibility and cost advantage of chemical processes leading to production of isoprene seems to be far from being dominated by a suitable biological substitute, the fear of extinction of non-renewable resources (raw material for chemical processes) in the near future prompts for a colossal expectation from the synthetic biology community. Technological advances in the field of metabolic engineering have made it possible to vigorously modify and swap genes among different organisms and push the limits for microorganisms to over-produce isoprene to an enormous extent. This review touches upon the limitations faced while improving isoprene titres and the meticulous strategies used to overcome them. It analyzes recent approaches that have resulted in significant improvement of biologically produced isoprene, summarizes the lessons learned from them, and compiles an exhaustive list of potential gene targets that could facilitate prospective research in this widespread arena.","PeriodicalId":16453,"journal":{"name":"Journal of Microbial & Biochemical Technology","volume":"36 1","pages":"73-81"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90249737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MNPS-IHSP nanoparticles is a specific and suitable nanocomposite that it have a mission as well as stabilizing the amp in the presence of silica coating (electrostatic bonding), that it called MNPS-IHSPA, and the results indicate a stabilization with a higher percentage of 85. It was beneficial to the silica coating. This measurement was performed by a UV-V is spectrophotometer analysis. Ultimately, in-vitro conditions, these magnetic nanoparticles that were migrating with ampicillin was tested on growing bacteria and resulted in the bacterial killing, indicating the antibacterial properties of magnetic nanoparticles.

No single species of microorganisms is able to degrade all components of the petroleum. Mutually beneficial interaction of microorganisms in the form of a consortium is required during the process of oil degradation. One form of mutually beneficial interaction between fungi and bacteria is biofilm formed by bacteria on fungal surface. The formation of bacterial biofilm on fungal surface was reported to increase the synergistic action of the two microorganisms in destroying certain complex compounds. This work was aimed to assess the capacity of hydrocarbon degrading-bacterial biofilm on the surface of hydrocarbon degrading-fungal surface to degrade hydrocarbons derived from drill cuttings. The hydrocarbon degrading-soil bacteria and fungi were isolated from different area in Yogyakarta, Indonesia after enrichment. The ability of bacteria to form biofilm on the surface of fungal hyphae was examined under light microscope with 1000x magnification after the addition of lactophenol. The effect of microbial amendment in the form of biofilm, in comparison with the planktonic culture, on degradation of hydrocarbons derived from drill cuttings were assessed by measuring the extractable petroleum hydrocarbon. The results showed that co-culture between fungi and bacteria which one among them or both of them have low ability to degrade hydrocarbon may significantly improve their ability and the ability of the co-culture to degrade hydrocarbon has no relationship with the ability of the bacteria to form biofilm on the surface of the fungal hyphae.","PeriodicalId":16453,"journal":{"name":"Journal of Microbial & Biochemical Technology","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89683019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nature of the antifungal activity, the antifungal parameters (MIC, MFC, IC50) and the percentage of survival of the strains were determined with the dilution method. On Alternaria sp., Penicillium sp. and Fusarium sp. strains, values of MFC/MIC ratios of water and 70% ethanol extracts of Capsicum annuum antillais were equal to two. Concerning Capsicum frutescens (soudanais, attie, doux and oiseau) varieties, these values varied from 1 to 2 on the fungal strains. These ratios for most of the strains were lower than 4. These extracts exerted a fungistatic action on chosen strains. The curves obtained had a declining appearance with more or less steep slopes depending on the extracts. These curved were used to obtain the inhibitory concentrations for 50% survival (IC50) of the moulds. The highest activity was achieved at the lowest IC50 values which varied from 0.2 mg/mL to 0.3 mg/mL. Therefore, Capsicum extracts proved to be active on in vitro growth of the fungal strains studied in a dose-dependent manner.","PeriodicalId":16453,"journal":{"name":"Journal of Microbial & Biochemical Technology","volume":"12 1","pages":"36-42"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85230812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objectives of the present investigation were (i) to isolate and characterize Trichoderma spp. from Menoufia Governorate and (ii) to evaluate the isolated Trichoderma spp. as potential biocontrol agents against some soil borne diseases. Soil samples were collected from nine districts and 25 isolates were obtained. Methods of identification of macroscopic and microscopic features, and the sequences of ITS and TEF1-α yielded three species; T. harzianum, T. longibrachiatum and T. asperellum. Phylogenetic tree of the identified 22 strains confirmed that the two strains T. longibrachiatum and T. asperellum came together in the same branch while the rest of the strains which were T. harzianum were on the other side of the tree. All 25 Trichoderma strains and isolates exhibited inhibition to the mycelial growth of four pathogenens. They were antagonized by competition mechanism against 000v m Sclerotium spp., by antibiosis against Fusarium oxysporum and partially against Sclerotium spp. and by mycoparasitism against Rhizoctonia solani. Also, they elucidated differences in total chitinolytic activity measured by two different methods and exochitonolytic activity.
