Biopolymer production using fungus Mucor racemosus Fresenius and glycerol as substrate

Abstract

SbstractThis study evaluated extracellular production of biopolymer using fungus Mucor racemosus Fresenius and glycerol as a carbon source. Initially employing conical flasks of 500 mL containing 100 mL of cultive medium with 0.18 ± 0.03 g.L -1 of microorganisms, the results showed that the best conditions of the variables studied were: initial concentration of glycerol 50 g.L gum formed and 75% glycerol consumption. These conditions produced a biopolymer with the molecular weight and total sugar content of 4.607×10 6 g.mol -1 (Da) and 89.5%, respectively.

An Overview of Bioplastic Research on Its Relation to National Policies

“…The common microbes that help in the production of PHA are bacteria such as Bacillus cereus, Bacillus megaterium uyuni S29 and Pseudomonas putida Bet 001 [6]. In addition, fungi, such as Mucor racemosis and Saccharomyces cerevisiae [7], and some algae, such as Chlamydomonas reinhardtii and Spirulina platensis [8] can also be used for PHA production. According to research journals, Pseudomonas sps., yeast isolate 1/yeast sps., and Calothrix scytonemicola are considered to be the best microorganisms that can produce a high rate of PHA [9][10][11][12].…”
