“…It has been evident that microalgae have proved to be a superlative candidate for the production of bioplastic but needs to be explored further in order to achieve commercial production of bioplastic emanated from microalgae independently or in consortium with bacteria. A substitute for a plastic bottle was also prepared by the composition of red algae powder and water ( Verlinden et al, 2007 ; Singh et al, 2017 ; Alcântara et al, 2020 ; Chia et al, 2020 ; Price et al, 2020 ; Shafqat et al, 2020 ). Therefore, commercialization of bioplastic emanated from algae can be achieved by investigating the bioplastic production potential of various algal species along with the metabolic engineering and evaluation of multiple aspects influencing the accumulation of bioplastics.…”

Impetuous urbanization and population growth are driving increased demand for plastics to formulate impeccable industrial and biomedical commodities. The everlasting nature and excruciating waste management of petroleum-based plastics have catered to numerous challenges for the environment. However, just implementing various end-of-life management techniques for assimilation and recycling plastics is not a comprehensive remedy; instead, the extensive reliance on finite resources needs to be reduced for sustainable production and plastic product utilization. Microorganisms, such as bacteria and algae, are explored substantially for their bioplastic production repertoire, thus replacing fossil-based plastics sooner or later. Nevertheless, the utilization of pure microbial cultures has led to various operational and economical complications, opening the ventures for the usage of mixed microbial cultures (MMCs) consisting of bacteria and algae for sustainable production of bioplastic. The current review is primarily focuses on elaborating the bioplastic production capabilities of different bacterial and algal strains, followed by discussing the quintessence of MMCs. The present state-of-the-art of bioplastic, different types of bacterial bioplastic, microalgal biocomposites, operational factors influencing the quality and quantity of bioplastic precursors, embracing the potential of bacteria-algae consortia, and the current global status quo of bioplastic production has been summarized extensively.

“…They are divided into two groups. The first group of biopolymers (natural) is obtained from living organisms, while the second one (synthetic) is produced during the polymerization of selected compounds contained in renewable resources [ 10 – 12 ]. Moreover, the natural biopolymers group consists of two subgroups: polysaccharides and proteins, while the synthetic biopolymers group is divided into degradable and non-degradable biopolymers [ 10 ].…”

“…Bacteria and microalgae are the most common forms of life in the world. However, the cultivation and harvesting of these microorganisms is limited due to the expensive equipment used in these processes [ 12 ]. According to Sirohi et al [ 80 ], PHB could be isolated from by-products created during production processes in agricultural, dairy, and food industries.…”

The article presents a literature review of the plant origin natural compounds with biocidal properties. These compounds could be used as modifiers of biodegradable materials. Modification of polymer material is one of the basic steps in its manufacturing process. Biodegradable materials play a key role in the current development of materials engineering. Natural modifiers are non-toxic, environmentally friendly, and renewable. The substances contained in natural modifiers exhibit biocidal properties against bacteria and/or fungi. The article discusses polyphenols, selected phenols, naphthoquinones, triterpenoids, and phytoncides that are natural antibiotics. Due to the increasing demand for biodegradable materials and the protection of the natural environment against the negative effects of toxic substances, it is crucial to replace synthetic modifiers with plant ones. This work mentions industries where materials containing natural modifying additives could find potential applications. Moreover, the probable examples of the final products are presented. Additionally, the article points out the current world’s pandemic state and the use of materials with biocidal properties considering the epidemiological conditions.

“…The residual biomass of cyanobacteria would therefore be well-used in the nutrition of livestock and aquaculture, but it is possible to go further in the optimization of this production chain. Residues from these same livestock farming can be re-applied as supplementary nutrients to the growth of cyanobacteria in an integrated bio-factory [ 184 ]. The return of cyanobacterial by-products such as pigments and biomass to animal feed completes the proposed circular economy.…”

Cyanobacterial Polyhydroxyalkanoates: A Sustainable Alternative in Circular Economy

Conventional petrochemical plastics have become a serious environmental problem. Its unbridled use, especially in non-durable goods, has generated an accumulation of waste that is difficult to measure, threatening aquatic and terrestrial ecosystems. The replacement of these plastics with cleaner alternatives, such as polyhydroxyalkanoates (PHA), can only be achieved by cost reductions in the production of microbial bioplastics, in order to compete with the very low costs of fossil fuel plastics. The biggest costs are carbon sources and nutrients, which can be appeased with the use of photosynthetic organisms, such as cyanobacteria, that have a minimum requirement for nutrients, and also using agro-industrial waste, such as the livestock industry, which in turn benefits from the by-products of PHA biotechnological production, for example pigments and nutrients. Circular economy can help solve the current problems in the search for a sustainable production of bioplastic: reducing production costs, reusing waste, mitigating CO2, promoting bioremediation and making better use of cyanobacteria metabolites in different industries.
