Testing of the Adhesion of Herpes Simplex Virus on Textile Substrates and Its Inactivation by Household Laundry Processes

Viral infections like Herpes simplex increasingly pose a serious threat to European health care systems and welfare of the population. Indirect transmission routes of infections via inanimate surfaces are often underestimated. In this study, we investigated the adhesion and persistence of Herpes simplex virus on cotton fabrics as well as its inactivation by domestic laundry. Virus adhesion to textile fibers was distinct, because viral DNA was detectable on fabrics for at least 48 hours after contamination as well as after home laundry. Particles remained infectious for several hours at room temperature and partially for 48 hours at 2℃ - 8℃. Nevertheless, domestic laundry was able to inactivate virus particles given that detergents were adequately used. This confirmed that standard household laundry processes, as established in Europe, are a suitable tool to reduce infectious Herpes virus particles from textiles, thereby supporting the prevention of infections circulating in the household and community.

A Wireless Intelligent Business Laundry Service System

For the business washing machine industry, most are currently using traditional manual service (the way cost is high, inefficient, low degree of intelligence) of the status quo. The wireless intelligent business laundry service system based on ESP8266 communication module is developed, which has the Wechat payment function and realizes the automatic control service of the washing machine. Firstly, the laundry wireless terminal will send a laundry request to the laundry control center when the customer is ready to wash. Secondly, after receiving the laundry request, control center will send WeChat Public Accounts, idle washing machine number and charges, as well as laundry service time and other information back to the wireless terminal to generate payment QR code. And then the customer scans QR code, when the control center receives the information that payment is successful, the system will automatically control the washing machine to complete the laundry service work. After testing, the system has the advantages of accurate control, low energy consumption, strong stability, accurate data transmission, low cost, strong practicability, and is conducive to promoting the development of the business laundry industry.

<i>Arthrobacter arilaitensis</i>Re117 as a Source of Solvent-Stable Proteases: Production, Characteristics, Potential Application in the Deproteinization of Shrimp Wastes and Evaluation in Liquid Laundry Commercial Detergents

The present study describes the characterization of crude protease extract from Arthrobacter arilaitensis Re117 and its evaluation in solid and liquid detergent. One caseinolytic protease clear band was observed in zymogram. The crude alkaline protease showed optimum activity at pH 9.0 and 50&degC, and it was highly stable over a wide range of pH from 8.0 to 9.0. Proteolytic enzymes showed extreme stability towards non-ionic surfactants (Tween 80, Tween 20 and Triton X-100) and stimulate activity towards oxidizing agents such as sodium perborate. They also showed high stability and compatibility with various laundry solid detergents from Tunisian market. The protease of A. arilaitensis Re117, was also tested for shrimp waste deproteinization to produce chitin. The protein removal with a ratio E/S of 20 was about 83%. The novelties of the Re117 protease include its high stability to organic solvents and surfactants. These unique properties make it an ideal choice for application in detergent formulations and enzymatic peptide synthesis. In addition, the enzyme may find potential applications in the deproteinization of shrimp wastes to produce chitin.

Chemical substances present in discharge water generated by laundry industry:Analytical monitoring

To our knowledge,precise data concerning the pollution in terms of qualitative and quantitative fluctuations in discharge water from the laundry sector have seldom been reported.This study investigated the chemical composition of the discharge water from a laundry industry.Over 160 chemical substances and 15 standard water parameters were monitored.The results showed that the discharge water presented both inorganic and organic polycontamination with a high degree of qualitative and quantitative variability.However,of all monitored substances,only five metals(Al,Cu,Fe,Sr,and Zn),five minerals(P,Ca,K,Na,and S),and alkylphenols were systematically present and quantifiable.For a daily average water flow of 129 m^(3),the released metal flux was 356 g/d.Substances,such as trichloromethane,brominated diphenyl ether(BDE)47,and fluorides,were occasionally found and quantified.Other substances,such as chlorophenols,organo-tins,and pesticides were never identified.All the samples had quantifiable levels in the chemical oxygen demand(COD),biological oxygen demand(BOD),and hydrocarbons.Only the concentrations of Zn(8.3 g/d),Cu(21.4 g/d),and BOD(57.4 g/d)were close to or above the regulatory values:74.0 g/d for Zn,9.0 g/d for Cu,and 57.0 kg/d for BOD.The data obtained from this study are useful to the choice of additional treatments for the reduction of pollutant fluxes.
