“…Production of hydrogen (H 2 ) as a clean fuel and bioplastics as alternatives to petroleum based non-biodegradable plastics are possible solutions for a cleaner and sustainable society [2][3][4]. Degradation of biowastes to methane (CH 4 ) and carbon dioxide is a multiple step process with possibilities to produce H 2 and bioplastics (from volatile fatty acids) as intermediates [1,5].…”

Hydrogen and Polyhydroxybutyrate Producing Abilities of Bacillus spp. From Glucose in Two Stage System

2011

Metabolic activities of four Bacillus strains to transform glucose into hydrogen (H 2 ) and polyhydroxybutyrate (PHB) in two stages were investigated in this study. Under batch culture conditions, Bacillus thuringiensis EGU45 and Bacillus cereus EGU44 evolved 1.67-1.92 mol H 2 /mol glucose, respectively during the initial 3 days of incubation at 37°C. In the next 2 days, the residual glucose solutions along with B. thuringiensis EGU45 shaken at 200 rpm was found to produce PHB yield of 11.3% of dry cell mass. This is the first report among the non-photosynthetic microbes, where the Bacillus spp.-B. thuringiensis and B. cereus strains have been shown to produce H 2 and PHB in same medium under different conditions.

“…001 [16][17][18][19]. Among the dark fermentative bacteria quite a few species are known to produce both the bioproducts: H 2 and PHB [2,9]. Recently, it has been shown that the two bioproducts can be obtained also by using the same strain-Bacillus cereus strain EGU43 and Bacillus thuringiensis EGU45 [11].…”

“…Synthesising PHB by using bacteria allows to obtain a polymer with highly regular structure [17,18]. Currently, the largest manufacturer of PHB is Telles (USA), producing that polymer under the trade name of Mirel [19]. The polymers of that group undergo degradation, among others, as a result of exposure to sunlight or microorganisms (bacteria of different species and fungi), both under aerobic and…”

“…At present, the best known and described biodegradable polymer is PLA, the largest manufacturer of which is Nature Works LLC (USA). PLA, known under the trade name of Ingeo [4], is produced from lactic acid, which, in turn, is obtained as a result of fermentation of glucose originating from plants. The polymer is produced, among others, using a synthetic method involving opening of the lactide ring.…”

This study presents the results of research concerning fabrication of nonwovens from biodegradable polymer blends using the melt-blown method. The experiments performed within the framework of the research confirmed the possibility of obtaining polymer composites based on polylactide (PLA) with poly(hydroxyalkanoates) (PHA) and another aliphatic-aromatic copolyester. The obtained products were subjected to the analyses of chemical structure using the Fourier Transform Infrared Spectroscopy(FTIR) Attenuated Total Reflectance(ATR) method. The physical and mechanical properties of the fabricated nonwoven layers were also tested, which confirmed a wide spectrum of their applicability, depending on the polymer composition used in production.

“…Plastics have thus become an imperative part of our modern life style and are being used in different sectors. These are typically petroleum based nonbiodegradable synthetic polymers accumulated in the existing ecosystem, which have resulted in a huge burden towards plastic waste management (Chanprateep, 2010). However, it is very difficult to stop the use of plastic made items due to their versatile properties, but it is possible to replace petroleumbased plastics with an alternative biodegradable polymer that mimic properties of plastic.…”

Aim : Methodology :Results : Interpretation :The present study aimed to produce and characterize polyhydroxyalkanoates by exploring high yielding bacterial isolates from fish industrial effluents.Industrial effluents samples were collected and processed for physico-chemical parameter and bacteriological analysis. The polyhydroxyalkanoates production efficacies of bacterial isolates were evaluated using submerged fermentation process and its primary characterization was carried out using fourier transform infra-red spectroscopy.Out of thirty three, five bacterial isolates showed accumulation of polyhydroxyalkanoates granule under Sudan black staining. These bacterial isolates were affiliated to genus (DS1 and DH1), (DP1 and DI4) and sp. DD5, based on morpho-physiological characterization. Under optimized condition, sp. DD5 produced 2.2 g l polyhydroxyalkanoate from 3.0 g of dry cell biomass. The Fourier Transform Infra-Red Spectroscopy primary structural characterization study depict high intense peak at 1720.50 cm corresponding to ester carbonyl (C=O) stretching vibration of polyhydroxybutyrate, which is the most common homopolymer of polyhydroxyalkanoates. This is the first report giving insight on non-growth associated polyhydroxybutyrate production (2.2 g l ) by sp. DD5 under submerged fermentation process, and further structural and thermal characterization is highly indispensible for application of polyhydroxybutyrate.
