“…This implies that the fungus R. bicolour detoxified the CGTR, allowing other bacteria to grow on the rubber more successfully. These experiments illustrate the potential for a multistep bioremediation process approach where rubber can first be detoxified and then devulcanized (Bredberg et al, 2002).…”

“…Detoxification increases the susceptibility of rubber to biodegradation, as well as reducing the environmental hazards associated with its disposal (Bredberg et al, 2002;Haroune et al, 2004). Research has shown that rubber materials can be devulcanized by the sulfur removing ability of sulfuroxidizing and sulfur-reducing microbes .…”

“…Many species of white rot fungi have efficient lignindegrading enzymes and are already used in soil bioremediation processes. Various species of white rot fungi are known to degrade xenobiotics that have very similar structures to aromatic compounds added to rubber (Bredberg et al, 2002). This suggests that white rot fungi could also be used to detoxify rubber.…”

“…) and strains of both white rot and brown rot fungi have been screened to identify those that can degrade aromatic compounds and that may therefore prove useful in rubber detoxification (see Table 2). Initially 15 fungal species were screened for their ability to biodegrade the aromatic polymeric dye polyvinylamine sulfonate anthrapyridone (Poly-R478) (Bredberg et al, 2002;Leidig et al, 1999). Three of these white rot fungal species, Pleurotus.…”

The accumulation of, and environmental hazards associated with, tire rubber and its disposal are major global concerns. The complex composition and structure of tire rubber and its additives make it highly resistant to natural degradation, but recently, microbial methods of detoxification and degradation of tire rubber have been developed. The polymers in tire rubber can be devulcanized by the activity of aerobic and anaerobic microbes and both the metabolic pathways and associated enzymes involved are becoming better known. Combining and adapting different rubber treatment processes could ultimately lead to more efficient ways of degrading and recycling tire rubber waste.

As far as microbial world concerned on earth, there are large number of domains has shown the potential for various applications. Fungal domain is one of them. Since the discovery of penicillin, various fungi has been harnessed for a large number of applications. Still there is a requirement of novel products for human welfare and development. So what are the fungi of next door? Are the fungal endophytes? Yes? This is the area untouched for a longer period of time. These fungi represent one of the most understudied and diverse group of organisms, are ubiquitous and occur within almost all the plants, including a broad range of hosts in various ecosystems, and therefore play an important role in the natural environment. Despite extensive work in this field, the products of these fungi remains poorly characterized. A large number of endophytic fungi such as Taxomyces, Pestalotiopsis, Muscodor, Piriformospora, Alternaria, Colletotrichum, Cryptosporiopsis, produce enormous valuable products for medicinal, agricultural and industrial importance. Some of the well-known products are taxol (Paclitaxel), serine hydrolases for polyurethane degradation, Annulene (Volatile organic compounds), Colletotric acid and Cryptocandin. So what next, are endophytic fungal metabolites are the future products? The present review explore the potential of these endophytic fungi with respect to the production of various novel secondary metabolites/products in comparison with the traditional fungi of importance.Petrini reported that these microorganisms colonize in healthy tissues of plants, at least for a part of their life cycle, without causing Biodiversity, Bioprospecting and DevelopmentTiwari, J Biodivers Biopros Dev 2015, 2:1 http://dx.

The common method for microbial desulfurization is the submerged cultivation method. However, its cost is high because of the high consumption of the medium. To cut costs and improve the desulfurization effect, the new half‐submerged cultivation method was used in the microbial desulfurization of waste latex rubber (WLR) by Sphingomonas species With this method, much more WLR was added per unit volume of the culture medium to be desulfurized, and the desulfurization process was done without stirring. The technical conditions, such as the addition of WLR, the addition of polysorbate 80 (Tween 80), and the desulfurization time, for the half‐submerged cultivation method were studied, and its desulfurization effect was compared with that of the traditional submerged cultivation method. The results show that the optimum conditions for the half‐submerged cultivation method were the addition of 40% w/v WLR in the medium without Tween 80 and desulfurization for 10 days. The X‐ray photoelectron spectroscopy and Fourier transform infrared spectroscopy results demonstrate that the decreases in the content of sulfur, SC bonds, and SS bonds on the surface of WLR after desulfurization by the half‐submerged cultivation method were greater than those after desulfurization by the submerged cultivation method. The composite of waste latex rubber desulfurized by the submerged cultivation method (SDWLR) and styrene–butadiene rubber (SBR) had better mechanical properties than the composite of waste latex rubber desulfurized by the half‐submerged cultivation method (HDWLR) and SBR. Scanning electron microscopy photographs showed that the combinations of HDWLR and the matrix were better than those of SDWLR and the matrix. Compared with the submerged cultivation method, the half‐submerged cultivation method not only reduced the cost of desulfurization but also improved the desulfurization effect. © 2014 Wiley Periodicals, Inc.
