Current application of algae derivatives for bioplastic production: A review

Bioplastic Production from Microalgae and their Applications- A Critical Review

“…A PHA is a form of energy storage that microalgae can use to overcome and acclimatize to extreme conditions that are a result of stress factors, both abiotic and biotic. Most of the interference is to and by these stress factors (Dang et al, 2022). Most of the interference to and stimulation of the synthesis of biopolymers comes from abiotic factors (Reddy et al, 2017).…”

“…Sunlight reaches the culture medium directly in open culture systems. Due to the low and unequal distribution of light radiation, it can sometimes be observed that growth is limited in these systems (Dang et al, 2022). Alternatively, fluorescent lamps can be used in closed systems utilizing photobioreactors to provide a better distribution of light.…”

“…Due to its influence on metabolic processes and biological reaction rates, temperature directly affects microalgal growth and biomass production. There are different optimal temperatures for different microalgae species (Dang et al, 2022). Microalgae accumulate lipids and PHAs under thermal stress according to several studies (Cruz et al, 2022).…”

“…Changes in salinity of the culture medium can adversely affect microalgae growth and composition as a result of osmotic and ionic stress (salt) as well as membrane permeability to ions (Reddy et al, 2019). Salinity changes in the culture medium are primarily caused by losses due to evaporation and precipitation in open systems (Dang et al, 2022). According to , it is not directly related to PHA production that salinity stress increases the synthesis of carotenoids and lipids.…”

Production of Polyhydroxyalkanoates from Microalgae- A Review

“…Hence, verifying the possible industrial applications of the obtained biopolymers is vital, to learn more about their properties (Costa et al, 2018). There have been several studies that evaluated the properties of biopolymers obtained from microalgae in comparison to synthetic polymers, but very few have addressed molecular mechanisms underlying the process of microalgae synthesizing biopolymers (Dang et al, 2022). Taking a general overview of the production methods of PHAs from microalgae, this review will focus on the properties and compositions of biopolymers, to compare them to petroleum-based plastics.…”
