Coir Fibre

A bacterial consortium developed on coconut husk leachates could ret coconut husk steeped for retting in rap water in a period of three months. The quality of the coir fibre obtained was comparable to traditionally retted fibre. The consortia could also bestow a greater degree of softness to the mechanically extracted coir fibre. Coir extraction can therefore be practiced by supplying the consortia for retting of husk for production of fibre and enhance the commercial utilization of the husk in coconut growing regions of Asia.

The influence of added coir (coconut) fibre of various lengths (from 2.5 mm to 10 mm) and dosages (up to 8 wt%) on the rheological properties of Trinidad Lake Asphalt (TLA) and Trinidad Petroleum Bitumen (TPB) was evaluated by measuring changes in the phase angle, δ (measure of the elasticity) and the complex modulus, G* (measure of the degree of stiffness). Results indicated that for both TLA and TPB, the highest values of G* (stiffest) and the lowest values of δ (most elastic) were observed for blends containing 2.5-mm coir fibre lengths for added coir concentrations of 6% and 8%, respectively. When compared to the unmodified TLA, the addition of 6 wt% of 2.5-mm coir fibre resulted in the largest significant increase in G* (7.3 times) as well as a significant decrease in δ (from 49.3° to 19.8°), representing a significant stiffening and increased elasticity of the modified blend. For TPB, the optimum concentration of added coir fibre occurred after the addition of 6 wt% of the 2.5-mm coir fibre, which resulted in the largest significant increase in G* of 5.4 times (stiffening) as well as a significant decrease in δ from 86.2° to 47.4° (increased elasticity as the material transformed from an almost viscous liquid to a semi-elastic solid) when compared to the unmodified pure TPB. The utilization of coir fibre for the rheological enhancement of Trinidad asphaltic materials can also provide an environmentally attractive option for solving the waste disposal issues associated with the dumping of waste coconut husk.

Ecological Pressure

The environment, including animals and animal products, is colonized by bacterial species that are typical and specific of every different ecological niche. Natural and human-related ecological pressure promotes the selection and expression of genes related to antimicrobial resistance (AMR). These genes might be present in a bacterial consortium but might not necessarily be expressed. Their expression could be induced by the presence of antimicrobial compounds that could originate from a given ecological niche or from human activity. In this work, we applied (meta)proteomics analysis of bacterial compartment of raw milk in order to obtain a method that provides a measurement of circulating AMR involved proteins and gathers information about the whole bacterial composition. Results from milk analysis revealed the presence of 29 proteins/proteoforms linked to AMR. The detection of mainly β-lactamases suggests the possibility of using the milk microbiome as a bioindicator for the investigation of AMR. Moreover, it was possible to achieve a culture-free qualitative and functional analysis of raw milk bacterial consortia.

The experiment was conducted at the Agriculture Research Station, College of Agriculture, Anand Agricultural University, Jabugam during three consecutive seasons of the years 2015-16 and 2016-17. This was to evaluate banana Pseudostem and maize fodder waste with and without cow dung and Anubhav biodegradable bacterial consortium (ABBC) for it bi-product in terms of vermi-composting, time required for degradation and the nutritive quality of vermicompost. The experiment consisted of eight treatments and conducted in RBD with three replications. Results shows that, the treatment Banana pseudostem + 5% Cow dung + Anubhav biodegradable bacterial consortium and the treatment Maize fodder waste + 5% Cow dung + Anubhav biodegradable bacterial consortium were significantly higher  for N, P, K content during all the three seasons and in pooled analysis with less number of days to harvest and high recovery. While, microbial count were recorded maximum in banana Pseudostem based vermicompost than maize fodder waste. Overall, vermicompost produced from the banana Pseudostem and maize fodder waste by using ABBC @ 1 lit/t and 5 % cow dung provided the major nutrients in more balanced proportion. The main perspectives of this study is to decrease the environmental pollution by making vermicompost from banana pseudostem waste or maize fodder (waste) instead of dumping on road side or burning or left in the field and also reduce the use of chemicals by using vermicompost.

In classical microbiology, developing a high-efficiency bacterial consortium is a great challenge for faster biodegradation of petroleum contaminants. In this study, a systematic experimental and mathematical procedure was adopted to establish a bacterial consortium for the effective biodegradation of heavy oil constituents. A total of 27 bacterial consortia were established as per orthogonal experiments, using 8 petroleum-degrading bacterial strains. These bacteria were closer phylogenetic relatives of Brevundimonas sp. Tibet-IX23 (Y1), Bacillus firmus YHSA15, B. cereus MTCC 9817, B. aquimaris AT8 (Y2, Y6 and Y7), Pseudomonas alcaligenes NBRC (Y3), Microbacterium oxydans CV8.4 (Y4), Rhodococcus erythropolis SBUG 2052 (Y5), and Planococcus sp. Tibet-IX21 (Y8), and were used in different combinations. Partial correlation analysis and a general linear model hereafter were applied to investigate interspecific relationships among different strains and consortia. The Y1 bacterial species showed a remarkable synergy, whereas Y3, Y4, and Y6 displayed a strong antagonism in all consortia. Inoculation ratios of different strains significantly influenced biodegradation. An optimal consortium was constructed with Y1, Y2, Y5, Y7, and Y8, which revealed maximum degradation of 11.238 mg/mL OD600 for oil contaminants. This study provides a line of evidence that a functional consortium can be established by mathematical models for improved bioremediation of petroleum-contaminated environment.

Removal Of Contaminants

In the present study a consortium of four naturally isolated bacterial strains was evaluated as remediation tool for simultaneous removal ofphenol and Cr (VI) from tannery effluent. Application of bacterial consortia to effluent (pH 4.6) resulted in 100 and 78% removal of initial 47mg L-1 phenol and 16 mg L-1 Cr (VI), respectively at 96 h of treatment. The consortium was also active in removal of contaminants with lowerremoval rate in presence of extraneous higher concentrations of both phenol and Cr (VI). Treatment in static mode also resulted in removal ofpollutants, however with increase in agitation speed simultaneous reduction of contaminants becomes faster. Overall it can be inferred fromthe study that the above formulated bacterial consortium could effectively be used for treatment of phenol and Cr (VI) laden tannery and otherindustrial effluents.DOI: http://dx.doi.org/10.3126/ijasbt.v3i1.11889   Int J Appl Sci Biotechnol, Vol. 3(1): 50-55

Antagonistic Interactions

ABSTRACT In nature, microbes interact antagonistically, neutrally, or beneficially. To shed light on the effects of positive interactions in microbial consortia, we introduced metabolic dependencies and metabolite overproduction into four bacterial species. While antagonistic interactions govern the wild-type consortium behavior, the genetic modifications alleviated antagonistic interactions and resulted in beneficial interactions. Engineered cross-feeding increased population evenness, a component of ecological diversity, in different environments, including in a more complex gnotobiotic mouse gut environment. Our findings suggest that metabolite cross-feeding could be used as a tool for intentionally shaping microbial consortia in complex environments. IMPORTANCE Microbial communities are ubiquitous in nature. Bacterial consortia live in and on our body and in our environment, and more recently, biotechnology is applying microbial consortia for bioproduction. As part of our body, bacterial consortia influence us in health and disease. Microbial consortium function is determined by its composition, which in turn is driven by the interactions between species. Further understanding of microbial interactions will help us in deciphering how consortia function in complex environments and may enable us to modify microbial consortia for health and environmental benefits.

End Uses

The mesocarp of the coconut or its husk is the source of coir. Coir fibre has several potential end uses like for the manufacture of various coir products predominantly coir floor coverings, yarn, rope, rubberized coir and latest as geotextile material. Coir is extracted from the coconut husk which is subjected to steeping in saline backwa­ters for six to nine months. This prolonged period of steeping is disadvantageous on economic considerations and also deprives the coir industry of sufficient raw material for the product sector. The treatment of selected strains of phenol de­grading bacterial cultures on to husks immersed for retting is reported to reduce the period of ret­ting to some extent 3. This paper reports the find­ings of a field study on the treatment of selected strains of bacteria on one lakh husks steeped for retting. Samples of husks drawn out after three months of steeping were observed to be fully retted and yielded fibre suitable for spin­ning superior quality coir yarn.
