A total of 42 isolates showed black-blue coloration when stained with Sudan black B, a preliminary screening agent for lipophilic compounds, and a total of 15 isolates showed positive result with Nile blue A staining, a more specific dye for PHA granules. The absorption bands at 2932 and 2954 cm−1 are due to C–H stretching vibrations of methyl, methylene groups. PHA methods are qualitative in nature. 1. In spite of these interesting properties, industrial production of PHAs is still not well established. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. This was calculated to determine the cellular weight and accumulation other than PHAs. PHAs are found to accumulate in varieties of microorganisms as reserve food material for example, Alcaligenes latus, Ralstonia eutropha, Azotobacter beijerinckii, Bacillus megaterium, and Pseudomonas oleovorans, including some fungi and archaea. The pellet along with 10 mL sodium hypochlorite was incubated at 50°C for 1 h for lyses of cells. The temperature was ramped at a heating rate of 10°C/min under nitrogen to a temperature (700°C) well above the degradation temperature of the polymers. Waste waters released from pulp and paperboard mills are typically rich in carbohydrates but poor in fixed nitrogen. From the literature, it has been found that the major cost in this biopolymer production is the cost of the substrate [9, 10] which accounts for more than 50% of production cost [5, 11] and makes the difference in price of poly-3-hydroxybutyrate (P3HB) from Biomer about 12 times the cost of polypropylene [12]. Sudan black B positive isolates were checked for PHA production by Nile blue A staining, a more specific stain for Polyhydroxyalkanoic acids (PHAs) by a more rapid and sensitive, viable colony method [14]. Morphological and biochemical characters of selected isolates.
