Response of culturable microbes on the surface of apples treated with slightly alkaline electrolyzed water (SAIEW) is largely unexplored. Thus, the aim of this study was to characterize culturable microbes on the surface of SAIEW treated ‘Granny Smith’ apples using conventional and molecular approach. Results showed that SAIEW treatments and storage duration influenced culturable microbes isolated from the surface of ‘Granny Smith’ apples stored at 5 °C for 21 days. Enterobacterial repetitive intergenic consensus (ERIC-PCR) analysis distinctively identified 27 groups of bacteria from 56 plate isolates. Using random amplified polymorphic DNA (RAPD-PCR) typing and RAPD1283 primers, 10 distinct band patterns were identified from 30 fungal isolates. Sequencing of 16S rRNA and intergenic spacer (ITS1 and ITS4) region, identified eight bacteria and four fungi, respectively, to species level. Study showed that SAIEW treatment inhibited growth of Staphylococcus epidermidis, S. capitis, Ochrobactrum soli, and Aspergillus inuii on the surface apples during storage.

Critical infrastructure (CI) such as the electrical grid, transportation systems and water resource systems are controlled by Industrial Control and SCADA (Supervisory Control and Data Acquisition) networks. During the last few years, cyber attackers have increasingly targeted such CI systems. This is of great concern because successful attacks have wide ranging impact and can cause widespread destruction and loss of life. As a result, there is a critical requirement to develop enhanced algorithms and tools to detect cyber threats for SCADA networks. Such tools have key differences with the tools utilized to detect cyber threats in regular IT networks. This paper discusses key factors which differentiate network security for SCADA networks versus regular IT networks. The paper also presents various approaches used for SCADA security and some of the advancements in the area.

The effect of replacement of in vitro maturation medium completely with the buffalo follicular fluid (buFF) on in vitro oocyte maturation of buffalo oocytes was studied. 5 to 8 buffalo cumulus oocyte complexes were cultured in a single drop with each of the eight media studied i.e., M199+steer serum (10% v/v), M199+steer serum (10% v/v)+PMSG, M199+buFF (10% v/v), M199+buFF (10% v/v)+PMSG, M199+buFF (50% v/v), M199+buFF (50% v/v)+ PMSG, buFF (100%) and buFF+PMSG at $39^{\circ}C$ and 5% $CO_2$ in air for 24 h. Supplementation of M199 with Steer serum alone resulted in IVM rate of 35% only. When the above medium was supplemented with PMSG, the maturation rate rallied to 82%. Significant increase in the maturation rates were observed when M199 was supplemented with increasing levels of buFF. A further increase in the maturation rate was also obtained when PMSG was incorporated into the medium of M199 supplemented with buFF. The rate of maturation was to the tune of 91% when oocytes were matured in buFF alone which was increased non significantly on the addition of PMSG. Highest maturation rate (97%) obtained with M199+buFF (50%v/v)+PMSG did not differ significantly from that obtained by either M199+buFF (10%v/v)+PMSG or buFF+PMSG. It is suggested that buFF alone without any supplementation can form the effective in vitro maturation medium for buffalo oocytes.
