“…As a result, intercellular enzymes decompose the PLA to carbon dioxide, water or methane. [145] In comparison to other biodegradable materials, PLA requires a long time to be degraded in soil because PLA is resistant to microbial attack.

Recently, thoughtful disagreements between scientists concerning environmental issues including the use of renewable materials have enhanced universal awareness of the use of biodegradable materials. Polylactic acid (PLA) is one of the most promising biodegradable materials for commercially replacing nondegradable materials such as polyethylene terephthalate and polystyrene. The main advantages of PLA production over the conventional plastic materials is PLA can be produced from renewable resources such as corn or other carbohydrate sources. Besides, PLA provides adequate energy saving by consuming CO2 during production. Thus, we aim to highlight recent research involving the investigation of properties of PLA, its applications and the four types of potential PLA degradation mechanisms. In the first part of the article, a brief discussion of the problems surrounding use of conventional plastic is provided and examples of biodegradable polymers currently used are provided. Next, properties of PLA, and (Poly[L‐lactide]), (Poly[D‐lactide]) (PDLA) and (Poly[DL‐lactide]) and application of PLA in various industries such as in packaging, transportation, agriculture and the biomedical, textile and electronic industry are described. Behaviors of PLA subjected to hydrolytic, photodegradative, microbial and enzymatic degradation mechanisms are discussed in detail in the latter portion of the article.

“…Enzymes isolated from Trichoderma viride were usually used to degrade waste paper, producing biofuel and other biochemicals in a simultaneous saccharification and fermentation (SSF) process as they contain endoglucanase, exoglucanase, xylanase, β ‐Xylosidase, and l ‐lysine α ‐oxidase . Trichoderma viride was also reported to degrade polycyclic aromatic hydrocarbons (PAHs) including bisphenol A in soil remediation and pyrene benzo[a]pyrene in water remediation .…”

Agricultural straw is abundant worldwide, but efficient production of lactic acid from straw is still challenging. In this paper, Trichoderma viride R16 was cultivated using corncob as the substrate in a fed-batch process, after which the enzymes from T. viride R16 broth were analyzed through protein mass J Liu et al.Spotlight: Dioxygenase from Trichoderma viride R16 enhances the lactic acid production using pretreated corncob spectrometry and used for lactic acid production. Dioxygenase activity was found in the T. viride R16 enzymes, and 0.2 g L -1 phenolics (vanillin, 4-hydroxybenzaldehyde, syringaldehyde) was degraded during enzyme production. Lactic acid production and yield from NH 3 -H 2 O 2 pretreated and washed corncob were increased by more than 24% and total phenolics was significantly lower using T. viride R16 enzymes compared with commercial enzymes in batch and fed-batch fermentation. These characteristics of T. viride R16 support industrial applications with efficient in situ detoxification of phenolic inhibitors without adding an extra step during lactic acid production from pretreated agricultural straw using simultaneous saccharification and fermentation.

“…PLA has not biodegradable completely, but also not pollute environment after biodegradation. Some studies have identified the biochemical processes and microbial compound in biodegradation of PLA by using the modern molecular biological techniques (e.g., PCR, high-throughput sequencing technology) and analytical techniques (e.g., 1H NMR, ESI-MS, IR, DSC, Xray, SEM, FTIR-ATR, GPC) [10,11].…”

Poly (lactic acid) (PLA) is a non-toxic, compostable bio based material derived from starch and/or sugar and has high mechanical strength and plasticity. It is accepted as GRAS (Generally Recognized as Safe) by the Food and Drug Administration (FDA) and suitable for using in food and beverage packaging. PLA is primarily obtained from lactic acid which can be produced from renewable substances such as potato, wheat and corn starch. Petroleum based polymers cause an increase in fuel energy utilization and greenhouse gas emissions, however PLA is environmental friendly. Various polymers (protein, polycaprolactone (PCL) and polyhydroxy butrate (PHB)), fillers (wood, flax, and ramie) and additives have been combining with PLA in order to develop the performance of film and reduce the cost. On the other hand, PLA plays an important role in nanotechnology applications. Nan fillers like clay, montmorillonite and silica can be used for fortifying PLA composites. As a packaging material, PLA has a potential for manufacturing flexible films, extruded packages, containers of yoghurt, bottled water and juices, cups and lunch boxes. Moreover, in antimicrobial packaging, PLA is an excellent material which is able to be successfully incorporated with plant extracts (e.g. lemon), essential oils (e.g. oregano oil), enzymes (e.g. lysozyme) and metals (e.g. silver) in order to develop antimicrobial characteristics. In this mini review, the significance of PLA based packaging systems in food applications is discussed.
