Fruits and vegetables have the highest wastage rates of 45% of any food. One of the recent research areas is food waste valorization as a potential alternative to the disposal of a wide range of organic waste using microorganisms as one of the strategies known as microbial valorization. Bacterial cellulose is best known microbial valorization product because of its low cost, environmentally friendly nature, renewability, nanoscale dimensions, biocompatibility and extremely high hydrophilicity. Therefore, present study focuses on the isolation, characterization and identification of cellulose producing bacteria from decaying apple waste. Cellulose producers were isolated from decaying apple waste. The bacterial isolates obtained were identified through the morphological biochemical, physiological and molecular identification. The bacterial isolates exhibited potential remediation options to biovalorize decaying fruit waste by producing value added products as well as in safe disposal of waste.

Fringescalesardinella or TambanSisik bones have been discovered can be utilized as sunscreen agent in cosmeceuticals. Its flesh is the main ingredient in keropoklekor or fish crackers in Malaysia and the bones contained very high hydroxyapatite (HAp), (Ca10(PO4)6(OH)2) compound which exhibit as UV light absorber. The percentage yields obtained from the hydrothermal extraction consist of 41.2 ± 0.66 % (w/w) of HApwhich was almost half of the dry weight of 100 g samples.The additional of manganeseand ferum,initiated the novel sunscreen materials from hydroxyapatite-Fe and hydroxyapatite-Mn doped (modified bones). The unmodified HAp recorded with SPF 20 and modified HAp-Mn measured with SPF 40. Modified HAp-Fe emulsions were recorded with SPF 50 as the highest SPF value. Therefore, the bones have been characterized using Fourier Transform Infrared Radiation (FTIR)spectroscopy and x-Ray diffraction (XRD).The results obtained clearly indicated that the HAp existence in waste of Fringescalesardinella bones with addition of FeCl2which exhibits high potential as sunscreen compared to manganese and unmodified bones. Thus, the utilization of waste from the fish bones not only produce value-added products from low-cost resources, but also help in reducing pollution to the environment and preserved the global sustainability.

It is important to establish new approaches to create value-added products, such as craftwork or artistic goods, that are different from traditional methods of realizing high-quality and low-cost products. Such a production technology is commonly called “dexterous machining.” This study addresses the creation of artistic products by using soft materials with complicated shapes by employing an aqueous solution of sodium acetate to fix a workpiece and to suppress the deformation. Experimental results show that the use of an aqueous solution of sodium acetate has the potential to realize the “dexterous machining” of soft objects.

AbstractRhodococcus spp. strains are widespread in diverse natural and anthropized environments thanks to their high metabolic versatility, biodegradation activities, and unique adaptation capacities to several stress conditions such as the presence of toxic compounds and environmental fluctuations. Additionally, the capability of Rhodococcus spp. strains to produce high value-added products has received considerable attention, mostly in relation to lipid accumulation. In relation with this, several works carried out omic studies and genome comparative analyses to investigate the genetic and genomic basis of these anabolic capacities, frequently in association with the bioconversion of renewable resources and low-cost substrates into triacylglycerols. This review is focused on these omic analyses and the genetic and metabolic approaches used to improve the biosynthetic and bioconversion performance of Rhodococcus. In particular, this review summarizes the works that applied heterologous expression of specific genes and adaptive laboratory evolution approaches to manipulate anabolic performance. Furthermore, recent molecular toolkits for targeted genome editing as well as genome-based metabolic models are described here as novel and promising strategies for genome-scaled rational design of Rhodococcus cells for efficient biosynthetic processes application.

Protein-energy malnutrition is one of the major public health problems in India affecting children under 5 years of age. The prevalence of underweight in children under 5 is 42.5% in India, being the highest globally. The need for low-cost supplemental food is vital under such conditions. This study aims to develop low cost and protein-rich value-added products from Tamarind seed flour. The incorporation of Tamarind seed flour (50%) in the development of cookies exhibited a significant level of increase in protein in cookies. The protein content of Control cookies was 5.65% and Tamarind seed flour incorporated cookies was 11.26%. This study depicted that Tamarind seed flour can be used as the replacement of conventionally used cereal flours to develop functional foods to curb protein-energy malnutrition.

Industrial biotechnology processes have recently been exploited for an economic utilization of wastes to produce value added products. Of which, fish waste is one of the rich sources of proteins that can be utilized as low cost substrates for microbial enzyme production. Fish heads, tails, fins, viscera and the chitinous materials make up the wastes from fish industries. Processing these wastes for the production of commercial value added products could result in a decrease in the cost of production. In addition, we can eliminate the pollution of the environment and health issues due to the improper disposal of these fish wastes. This review highlights the potential use of fish waste as a cheaper substrate for the production of economically important protease enzyme.

Lignocellulose waste has great potential to be converted into value added products sustainably as it is readily available at low cost. The aim of this study is to examine the amount of glucose produced from coconut pulp and coconut empty fruit bunch using acid hydrolysis. Sodium hydroxide pretreatment is carried out at 70oC using different concentrations of sodium hydroxide which are 5%, 10%, 15% and 20% v/v for a duration time of 2 hours. Optimum pretreatment is evaluated using Fourier Transform Infra-Red (FTIR) analysis. It is observed that optimum pretreatment is at 20% v/v sodium hydroxide. The optimum samples are then hydrolysed using concentrations of 5%, 10%, 15% and 20% v/v of sulphuric acid at different temperatures of 30, 50, 70 and 90oC for 2 hours. Glucose concentration is analysed using an ultraviolet (UV) Spectrophotometer. The highest glucose concentrations obtained are 0.895 g/L and 0.550g/L for coconut pulp and coconut empty fruit bunch, respectively at 20% v/v acid concentration and a temperature of 90oC.
